Type I & Type II Collagen: Structure Influences Staining Patterns
Fibrillar collagens have a unique structure that influence collagen sample preparation and the immunostaining patterns of collagen samples. As such, understanding collagen structure is vital for interpreting SDS-gel and Western Blot results. Here, Chondrex, Inc. scientists share important information about collagens structure and its implications for collagen immunostaining. Read More
Ovalbumin Epitopes in Cell-Mediated Immunity, Humoral Immunity, and Anti-OVA Monoclonal Antibodies
Ovalbumin has long been used as an antigen in pre-clinical allergic disease research. To better understand how ovalbumin immunizations influence immune responses, extensive research has been done to identify T-cell and B-cell epitopes of Ovalbumin. This blog discusses the significance of various OVA epitopes for cell-mediated and humoral immune responses. Read More
Ovalbumin: Ideal Model Antigen for Immunology Research
Ovalbumin (OVA), the primary egg white allergen in infants, was used extensively in early immunology studies investigating antibody-antigen interactions. This historical usage, along with the commercial availability of purified OVA and Anti-OVA Antibody Detection Kits, has OVA a convenient and cost effective model antigen for a variety of research topics: IgE-mediated allergies, vaccines, and oncology.

Troubleshooting the Collagen-Induced Arthritis Model
While the Collagen-Induced Arthritis model is the most popular rheumatoid arthritis model, there are many sources of variation that can alter the development of the model. Here is a list of factors to consider when planning a CIA experiment in order to reduce sources of variation and increase the reproducibility of your model. Read More
Arthritis Models: Using CIA and CAIA to Study RA GWAS Risk Loci
Genome Wide Association Studies (GWASs) have identified numerous genes as potential therapeutic targets for rheumatoid arthritis and other autoimmune diseases. However, determining the roles of these genetic factors in RA pathogenesis is virtually impossible. Therefore, the mouse Collagen-Induced Arthritis and Collagen Antibody-Induced Arthritis models are useful tools to parse a genetics mechanisms for autoimmune arthritis. Read More
