NCBI Gene Id: 930
Swissprot Id: P15391
The CD19 antigen (95kDa) 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 glyco-protein whose in vitro inhibition will influence B cell activation and proliferation. - See more at: http://www.avivasysbio.com/sd/tds/html_datasheet.php?sku=OAAD00406
