KIR2DL2/CD158b1 Protein, Human (HEK293, His-Avi)

Cat. No.: HY-P77970
COA Handling Instructions

KIR2DL2/CD158b1, found on NK cells, functions as a receptor for HLA-Cw1, Cw3, Cw7, and Cw8 allotypes. Its key role is to inhibit NK cell activity, serving as a regulator to prevent cellular lysis. Interacting with specific HLA-C molecules, KIR2DL2/CD158b1 contributes to the delicate balance of inhibitory signals in the immune system, shaping the responsiveness of NK cells to potential targets. KIR2DL2/CD158b1 Protein, Human (HEK293, His-Avi) is the recombinant human-derived KIR2DL2/CD158b1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of KIR2DL2/CD158b1 Protein, Human (HEK293, His-Avi) is 224 a.a., with molecular weight of 45-50 kDa.

Background

KIR2DL2/CD158b1, located on natural killer (NK) cells, serves as a receptor for HLA-Cw1, Cw3, Cw7, and Cw8 allotypes. Its primary function is to exert inhibitory effects on NK cell activity, acting as a regulator to prevent cellular lysis. Through specific interactions with distinct HLA-C molecules, KIR2DL2/CD158b1 contributes to the finely tuned balance of inhibitory signals within the immune system, influencing the responsiveness of NK cells to potential targets.

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
