The clone 4G7 recognizes a 90-kDa CD19 antigen that is present on human B lymphocytes. CD19 is a 95 kD type I transmembrane glycoprotein also known as B4. The CD19 antigen is present on approximately 7% to 23% of human peripheral blood lymphocytes and on spleenocytes, and on human B lymphocytes at all stages of maturation but is lost on terminally differentiated plasma cells. CD19 does not react with resting or activated T lymphocytes, granulocytes, or monocytes.
iFluor™ fluorophores are optimized for strong fluorescence, high photostability and pH independence on proteins. They are avaialble to span the full UV-visible-IR spectrum. APC-iFluor™700 (also referred to APC-Cy7) is a great alternative to APC eFluor? 780. Do you need an antibody for an antigen you don't see on our website? Do you need a different conjugation than what we have listed? We have a wide selection of antigens with a variety of conjugations available. Please reach out to us at [email protected].
