Vector Labs Ab03144-201.1 Anti-CD20 [NCD1.2 (scFv-3)], Dog IgG2 (IgG-B), kappa (200 μg)

Quick Overview
The original antibody was generated by immunizing 5–8 weeks old BALB/c mice with a canine CD20 peptide (NCDPANPSEKNSLSIQYCGS) at a final concentration of 100 μg/ml in complete Freud’s adjuvant.

Chimeric Use Statement:This chimeric dog antibody was made using the variable domain sequences of the original Mouse IgG2a format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement:This antibody is specific for the amino acid sequence 'PSEKNSLSI' of dog CD20. It also cross reacts with human CD20. CD20 is a 33kDa tetraspanning transmembrane phosphoprotein which is expressed in pre B-cells. This B-lymphocyte-specific membrane protein plays a role in the regulation of cellular calcium influx necessary for the development, differentiation, and activation of B-lymphocytes. It also functions as a store-operated calcium (SOC) channel component promoting calcium influx after activation by the B-cell receptor/BCR.
Application Notes:The original IgG antibody binds biotinylated canine CD20 peptide with an relative affinity of kd= 340 pM. This antibody was able to recognize endogenous canine CD20 protein in canine 3132 lymphoma cells and also cross reacted with transfected human GFP-CD20 expression construct in H1299 cells in an western blot assay. This antibody can detect canine CD20 expressed on normal peripheral blood, medium-sized B-cell lymphoma and diffuse large B-cell lymphoma in a flow cytometric assay. It could not detect CD20 -negative peripheral T-cell lymphoma cells in flow cytometry. This antibody was also used in the immunohistochemical staining of formalin fixed samples of diffuse large B-cell lymphoma and lymphoma histotypes of B-cell origin, including marginal zone lymphoma, follicular lymphoma, and small lymphocytic lymphoma.
