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.

MD Biosciences Releases New - Improved Collagen Type II ELISA

Posted by Amy Clausen on Feb 28, 2007 11:36:00 AM


St Paul, MN, January 9, 2007 - MD Biosciences, a global biotechnology company focused in inflammations research, accounces the launch of its new and improved Collagen Type II (CII) ELISA for the study of collagen metabolism. CII is a triple stranded pro-molecule that is found predomiinantly, but not exclusively, in cartilage. It's promary role is to provide cartilage with tensile strength and elasticity. Autoimmunity to CII is thought to play a role in the pathogenesis of many autoimmune diseases such as rheumatoid arthritis.

This ELISA offers many improvements over other commercially available CII ELISAs such as increased sensitivity, reproducibility, and accuracy for the reliability of results. The ELISA is designed to quantify the amount of collagen type II produced by cells or present in tissue across a variety of species. The ELISA is also highly specific to CII offering no cross-reactivity to other types of collagen providing reliable results.

In addition to performance improvements, user-friendly improvements such as pre-coated microplates and ready-to-use reagents increase the usability and decrease the preparation time allowing researchers to obtain rapid results in less than 5 hours.
