MD Biosciences Releases Human Collagen Type I ELISA

Posted by Amy Clausen on Feb 9, 2009 11:10:00 AM


St Paul, MN February 9, 2008MD Biosciences, a global biotechnology company focused in inflammations and neurology research, announces the recent launch of its new Human Type I Collagen (CI) ELISA, Catalog # M036007, for use with cell culture supernates. The ELISA is provided with all reagents required including a pre-coated microplate eliminating the need for a 24 hour blocking incubation found with other commercially available kits. Results are achieved in under 3 hours and are sensitive, accurate and reproducible.


Human Collagen Type I ELISA Kit specifications include:

-        100 uL sample size

-        Dynamic range of 0.062 – 5 ug/mL

-        Sensitivity < 0.35 ug/mL

-        Length of assay < 3 hours

-        Crossreactivity is < 0.1% with Type II and Type IV collagen

Collagen Type I (COL1A1, COL1A2) is the most abundant protein and is found in the skin, connective tissue, tendons, ligaments, cornea, intevertebral disks, scar tissue, and lung. It has been found to be involved in many human diseases such as fibrosis, osteoporosis, cancer and artherosclerosis. It is a fibrillar collagen comprised of 3 polypeptide chains (alpha-chains), which form a unique helical structure. It is a heterotrimer of two a1(I) and one a2(I) chains. Collagen Type I molecules form cross-striated fibrils in the extracellular space, giving the tissues their mechanical strength and providing the major biomechanical scaffold for cell attachment and anchorage of macromolecules. Collagen Type I also interacts with many cells, such as fibroblasts, and with platelets during blood clotting.

 


The addition of the Human Collagen Type I assay enhances the line of collagen-related products offered by MD Biosciences, which include Collagen Type II ELISA; Anti-Collagen Type II ELISAs for IgG; IgG2a and IgG2b isotypes (see http://www.mdbiosciences.com/elisas_assays.html for a list of current ELISAs); Collagen Type II Staining kit, Bovine and Chicken Collagen Type II http://www.mdbiosciences.com/typeIICollagen.html), Collagen Antibodies and ArthritoMab Anti-Collagen Antibody Cocktail (http://www.mdbiosciences.com/ArthritoGenicMonoclonalAntibodyCocktailProduct.html)

Lumican & Keratocan Monoclonal Antibodies | Eye/Cornea

Posted by MD Biosciences on Dec 9, 2008 11:12:00 AM


St Paul, MN, December 9, 2008 – MD Biosciences, a global biotechnology company focused in inflammations and neurology research, announces the launch of Lumican and Keratocan Monoclonal Antibodies. Both Lumican and Keratocan play a role in the development and maintenance of corneal transparency making them ideal for applications in Eye and Cornea Research.

 

Lumican and Keratocan belong to the Small Leucine Rich Proteoglycan (SLRP) family. Keratocan was originally found to be a cornea specific keratan sulphate proteoglycan. Lumican is a proteoglycan expressed in extracellular matrix (ECM) and connective tissues where it has been reported to contribute to collagen fibrillogenesis, tissue hydration, migration and proliferation. Lumican modified with keratan sulphate, constitutes one of the major proteoglycans of the corneal stroma, where it stimulates cell migration on the corneal epithelium and is also believed to play a regulatory role for keratocan. Mutations of keratocan cause cornea plana in humans, which is often associated with glaucoma, whereas the absence of Lumican leads to formation of cloudy corneas. This suggests that Keratocan and Lumican have different roles in regulating the formation of stromal extracellular matrix.

 

Both the Lumican Monoclonal Antibody (Catalog 1042007) and the Keratocan Monoclonal Antibody (Catalog 1042008) are IgM antibodies that are affinity purified on a thiophilic column. The Lumican antibody recognizes a protein epitope and is specific for human, bovine, mouse and porcine tissues. The keratocan antibody recognizes a protein core epitope and is specific for human, bovine, porcine, mouse and chicken tissues. Both antibodies are supplied as liquid, ready to use, at a concentration of 0.1 mg/mL for ELISA, Western Blot and IHC applications.

 

In addition to Lumican and Keratocan antibodies, MD Biosciences also supplies a line of Aggrecan, Collagen, MMP, Proteoglycan, Protease, and T cell specific reagents that encompass natural and recombinant proteins, antibodies, ELISAs and assays. For additional information on any of the reagents or services provided, please visit the website at www.mdbiosciences.com.

New Mouse anti-Collagen Type II (anti-CII) ELISAs.

Posted by Amy Clausen on Mar 3, 2008 11:27:00 AM


St Paul, MN March 4, 2008 – MD Biosciences, a global biotechnology company focused in inflammations research, announces the recent launch of its new line of Mouse anti-Collagen Type II (anti-mouse CII) ELISAs. The new Mouse anti-collagen CII ELISAs allow you to measure antibodies generated against the species of collagen used in the induction of arthritis in mice (bovine, human, mouse, rat, chicken, porcine). IgG and two subclasses (IgG2a and IgG2b) are now available as ready-to-use ELISAs that provide fast, accurate and reliable results.

 

The Collagen-induced arthritis (CIA) model is one of the most widely used models for the study of RA. Collagen type II (CII) in adjuvant is used to induce arthritis by triggering autoreactive B cells, which play an important role in the development of arthritis. This B cell response to CII is strictly T cell dependent, where the B cells predominantly switch isotype to IgG.

 

The anti-Type II Collagen ELISAs offer many improvements over other commercially available anti-Collagen Type II ELISAs. The kits come ready to use eliminating any plate coating or blocking as well as eliminates lengthy sample incubations. The assays can be completed in under 3 hours using only 100 uL of sample. Performance characteristics such as precision CVs less than 10%, recovery and linearity averaging at 82% and 102% respectively, and cross-reactivity with other collagen types of less than 0.004% provide reliable, accurate and sensitive assays for the detection mouse Collagen Type II antibodies.

 

The addition of these assays enhances the arthritis products and services currently offered by MD Biosciences. Research products include assays for measuring type II collagen and antibodies, assay for staining type II collagen, induction reagents such as collagen, adjuvant and ArthritoMabÒ antibody cocktail. Pre-clinical services include collagen-induced arthritis (CIA), Antibody induced arthritis (CAIA), Adjuvant Induced Arthritis as well as in vitro disease models providing the researcher a well-rounded approach for using MD Biosciences products in-house as well as outsourcing other areas of their drug discovery platform.

MD Biosciences Releases Mouse OVA-IgE ELISA

Posted by Amy Clausen on Aug 3, 2007 11:30:00 AM

MD Biosciences, a global biotechnology company focused in inflammations research, announces the recent launch of its new Mouse OVA-IgE ELISA. The OVA-IgE ELISA offers researchers sensitive, reproducible, accurate and reliable results for the measurement of OVA specific IgE in mouse serum and cell culture supernate samples. The kit is ready-to-use with all necessary reagents and can be completed in under 2.5 hours, requires small sample sizes and measures levels down to 7.8 ng/mL with a sensitivity of less than 3.8 ng/mL.

Ovalbumin is widely used in inducing an allergic response in mouse models of allergic asthma. Through T cell and B cell signalling, IgE production is stimulated and released into the bloodstream where IgE attaches to cells such as mast cells and basophils. These cells are then activated after the IgE is cross-linked with antigen, initiating the allergic cascade.

In addition the Mouse OVA-IgE ELISA, MD Biosciences also offers other reagents such as T1/ST2 antibodies, in vitro assay services and efficacy disease models for the study of allergic asthma.

High ArthritoMabTM Antibody Cocktail Activity |18-day RA Model Balb/c Mice

Posted by Amy Clausen on Apr 3, 2007 11:33:00 AM

MD Biosciences releases histology results from an 18-day model of arthritis induced using the ArthritoMab(TM) cocktail of arthritogenic antibodies in Balb/c mice. Results show significant histological changes in the joint of the arthritis group as compared to the normal control group after just 18 days, providing researchers valuable data quickly compared to the traditional collagen-induced arthritis (CIA) model, which can take several weeks or more to produce similar histological results.

Results show significant histological changes in the joint of the arthritis group as compared to the normal control group after just 18 days, providing researchers valuable data quickly compared to the traditional collagen-induced arthritis (CIA) model, which can take several weeks or more to produce similar histological results. Figures 1-3 show the effectiveness of the arthritogenic antibodies, with mean histology scores and staining sections indicating the degree of erosion, hyperplasia and infiltration in the joint of the arthritis group as compared to the control group.

 

ArthritoMab histology

 

 

The ArthritoMabTM Arthritogenic Antibody Cocktail is comprised of 4 monoclonal antibodies to collagen type II (CII) that have been chosen for their epitope specificity. An antibody response to certain epitopes is better associated with arthritis than a response to other epitopes. In the CIA model, the antibody response correlated with arthritis was mainly associated with binding to the epitopes C1, J1, and U1. The ArthritoMabTM monoclonal antibodies were selected to bind to the epitopes C1, J1, U1 and D3 - which are spread over the entire CII region (fragments CB8, CB10 and CB11) encouraging better immune complex formation on the cartilage surface for the initiation of arthritis. The antibody-induced arthritis model using the ArthritoMabTM Arthritogenic Antibody cocktail is a rapid alternative the CIA model.
