SKU:: 521122
Purity:: Purified by affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Mouse
Immunogen:: Purified recombinant fragment corresponding to human CD19 expressed in E. coli.
Format:: Supplied as a liquid in PBS (without Mg2+ and Ca2+), pH 7.4, 0.02% sodium azide, 50% glycerol.
Extra Details:: The CD19 antigen (95kD) is expressed from the earliest stage of B progenitor development, on all peripheral B cells including germinal centre B cells, and all B cell lines and B cell leukaemia tested. T cell and monocytic cell lines are negative and the antigen is lost on B cell maturation to plasma cells. The antigen is a type I integral membrane glycoprotein whose in vitro inhibition will influence B cell activation and proliferation. Applications: Suitable for use in Immunocytochemistry, ELISA and Flow Cytometry. Other applications not tested. Recommended Dilution: ELISA: 1:10,000 Immunocytochemistry: 1:200-1:1000 Flow Cytometry: 1:200-1:400 Optimal dilutions to be determined by the researcher.
