CD19 is a 95kD transmembrane glycoprotein with two Ig-like C2-set domains. CD19 regulates B cell development and activation through interactions with CD21, CD22, and the B cell receptor. CD19 polymorphisms and upregulation lead to the development of autoimmunity by promoting autoantibody production. Within the extracellular domain, human CD19 shares 57% aa sequence identity with mouse and rat CD19.
Suitable for use in Flow Cytometry. Other applications not tested.
Flow Cytometry: Neat. 10ul labels 1x10e5 cells.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C before opening. DO NOT FREEZE! Stable at 4 degrees C as an undiluted liquid. Dilute only prior to immediate use. Stable for at least 6 months at 4 degrees C. Freezing R-Phycoerythrin (PE) conjugates will result in a substantial loss of activity. PE conjugates are sensitive to light.
