Specificity and cross reactivity
CD19 B cell differentiation antigen, Mr 95 kDa CD19 is a monomeric transmembrane glycoprotein expressed at relatively constant levels throughout B cell development from early pro-B/pre-B cells (i.e., B220^+/CD43^+/HSA^+) through fully differentiated B cell stages. ^1-7 Terminally differentiated plasma cells do not express CD19. ^1 In humans, the CD19 molecule on the surface of mature B cells associates with CD21 (CR-2) and CD81 (TAPA-1), and this multimolecular complex synergizes with surface immunoglobulin to provide signal transduction and promote cellular activation. ^3, 4 All splenic and peritoneal IgM^+ cells of both B-1 and B-2 lineages are CD19^+, with B-1 cells expressing higher levels of CD19 than B-2 cells in these sites. ^1, 7 Recent studies with CD19-deficient mice have suggested that this molecule may not be required for normal generation and maturation of B cells in the bone marrow. ^7; Since it is not possible to test each and every species our knowledge on the corss reactivity of the antibodies is limited. This particular antibody might cross react with speacies outside of the listed ones.

Test
Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
