Fc gamma RIIB/CD32b Protein, Human (Biotinylated, HEK293, His-Avi)

Cat. No.: HY-P75211
Handling Instructions Technical Support

Fc gamma RIIB/CD32b protein is a low-affinity receptor for immunoglobulin gamma and plays a key role in immune responses. It mediates phagocytosis of immune complexes and regulates antibody production by B cells. Fc gamma RIIB/CD32b Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Fc gamma RIIB/CD32b protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Description

Fc gamma RIIB/CD32b protein is a low-affinity receptor for immunoglobulin gamma and plays a key role in immune responses. It mediates phagocytosis of immune complexes and regulates antibody production by B cells. Fc gamma RIIB/CD32b Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived Fc gamma RIIB/CD32b protein, expressed by HEK293 , with C-Avi, C-His labeled tag.
Background

Fc gamma RIIB/CD32b Protein serves as a receptor for the Fc region of complexed or aggregated immunoglobulins gamma, displaying low affinity. It plays a pivotal role in various effector and regulatory functions, including the phagocytosis of immune complexes and the modulation of antibody production by B-cells. Upon binding to this receptor, there is a down-modulation of the preceding state of cell activation triggered through antigen receptors on B-cells (BCR), T-cells (TCR), or another Fc receptor. Notably, isoform IIB1 is unable to mediate endocytosis or phagocytosis, while isoform IIB2 does not induce phagocytosis. Fc gamma RIIB/CD32b interacts with INPP5D/SHIP1, FGR, and LYN.

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.

  • Reconstitution Calculator

  • 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
