Quantitative Human CD19 (Glycosylated) Sandwich ELISA Kit

The quantitative human CD19 (glycosylated) sandwich ELISA kit is designed to detect human cluster of differentiation 19 (CD19) levels. CD19 is a protein found on the surface of B cells. This protein functions as a co-receptor in B cell signaling, which plays a role in B cell development and activation. The kit is suitable for various biological samples such as tissue homogenates, cell lysates. Its sensitivity is 0.121 ng/mL, which can accurately detect low concentrations of CD19 in the sample.

The quantitative human CD19 (glycosylated) sandwich ELISA kit is used to measure CD19 levels in biological samples. Researchers use it in studies investigating B cell lymphomas, autoimmune diseases, and immune responses. The kit is a valuable tool in cancer research and the development of immunotherapies.

Intra-Assay: n=20, CV <8%;
Inter-Assay: n=20, CV <10%;

Serum sample: n=5, 85-100%;
Plasma sample: n=4, 90-110%;

The standard curve is for reference only, and a new standard curve should be generated for each set of samples tested.
