Product Description

CD19 is a 95 kD glycoprotein also known as B4. It is a member of the Ig superfamily, expressed on all pro-B to mature B cells (during development) and follicular dendritic cells. Plasma cells do not express CD19. CD19, in association with CD21 and CD81, forms a molecular complex integral to B cell activation.
100μg
Verified Reactivity: Mouse
Antibody Type: Monoclonal
Host Species: Rat
Immunogen: Transfected k562 cells expressing the extracellular domain of murine CD19.
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
