Preparation and Storage
- 12 months from date of receipt, 2 to 8 °C as supplied.
CD19 is a 95 kDa 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 up‑regulation lead to the development of autoimmunity by promoting autoantibody production. Within the extracellular domain, human CD19 shares 57% amino acid sequence identity with mouse and rat CD19.
