The CD19, clone SJ25-C1, fluorescein (FITC) dye conjugate is a monoclonal mouse antibody that recognizes the CD19 antigen. Commonly used, fluorescein conjugates provide a relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility. Fluorescein conjugates have been superseded by the Alexa Fluor® 488 dye conjugates, which exhibit a fluorescence emission profile almost identical to fluorescein and provide pH-insensitive fluorescence between pH 4 and 10. Review additional information about the CD19, Alexa Fluor® 488 dye conjugate.


Specificity for CD19
This antibody recognizes the CD19 B cell differentiation antigen. This antigen is expressed on B cells throughout their development but is not expressed on terminally differentiated plasma cells. CD19 serves as an adapter molecule involved in B cell signaling.
