CD20/MS4A1 Protein, Human (His-Avi)

Cat. No.: HY-P78086
Handling Instructions

CD20/MS4A1 protein is a B lymphocyte membrane protein that plays a crucial regulatory role in cellular calcium influx, which is essential for the development, differentiation and activation of B lymphocytes. As part of a store-operated calcium (SOC) channel, it promotes calcium influx upon B cell receptor/BCR activation. CD20/MS4A1 Protein, Human (His-Avi) is the recombinant human-derived CD20/MS4A1 protein, expressed by E. coli , with C-Avi, C-His labeled tag. The total length of CD20/MS4A1 Protein, Human (His-Avi) is 48 a.a., with molecular weight of ~16.8 kDa.

Background

The CD20/MS4A1 protein, a B-lymphocyte-specific membrane protein, plays a crucial role in regulating cellular calcium influx essential for the development, differentiation, and activation of B-lymphocytes. It functions as a component of the store-operated calcium (SOC) channel, promoting calcium influx upon activation by the B-cell receptor/BCR. CD20/MS4A1 forms homotetramers, contributing to its structural organization and functional role in calcium signaling. Notably, it interacts with both the heavy and light chains of cell surface IgM, the antigen-binding components of the BCR, highlighting its involvement in the B-cell receptor complex and underscoring its significance in B-cell activation and immune responses.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
