KIR2DS3 Protein, Human (P.pastoris, His)

Cat. No.: HY-P71815
Handling Instructions

KIR2DS3, present on NK cells, selectively recognizes HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 lacks inhibitory effects on NK cell activity. Its role is likely in activating or modulating NK cell functions, contributing to the nuanced balance of signals regulating the immune response. KIR2DS3 Protein, Human (P.pastoris, His) is the recombinant human-derived KIR2DS3 protein, expressed by P. pastoris , with N-His labeled tag.

Description

KIR2DS3, present on NK cells, selectively recognizes HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 lacks inhibitory effects on NK cell activity. Its role is likely in activating or modulating NK cell functions, contributing to the nuanced balance of signals regulating the immune response. KIR2DS3 Protein, Human (P.pastoris, His) is the recombinant human-derived KIR2DS3 protein, expressed by P. pastoris , with N-His labeled tag.
Background

KIR2DS3, expressed on natural killer (NK) cells, serves as a receptor specifically recognizing HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 does not exert inhibitory effects on NK cell activity. Instead, it likely plays a role in activating or modulating NK cell functions, contributing to the intricate balance of signals that regulate the immune response.

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
