CD161 Protein, Human (HEK293, Fc)

Cat. No.: HY-P72750
SDS COA Handling Instructions

CD161 protein plays a crucial role in inhibiting NK cell toxicity by activating specific acid sphingomyelinase/SMPD1 and increasing ceramide levels. Activation stimulates AKT1/PKB and RPS6KA1/RSK1 kinases, enhancing anti-CD3-induced T cell proliferation. CD161 Protein, Human (HEK293, Fc) is the recombinant human-derived CD161 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CD161 Protein, Human (HEK293, Fc) is 159 a.a., with molecular weight of 55-70 kDa.

Description

CD161 protein plays a crucial role in inhibiting NK cell toxicity by activating specific acid sphingomyelinase/SMPD1 and increasing ceramide levels. Activation stimulates AKT1/PKB and RPS6KA1/RSK1 kinases, enhancing anti-CD3-induced T cell proliferation. CD161 Protein, Human (HEK293, Fc) is the recombinant human-derived CD161 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CD161 Protein, Human (HEK293, Fc) is 159 a.a., with molecular weight of 55-70 kDa.

Background

CD161 Protein assumes a crucial role in inhibiting natural killer (NK) cell cytotoxicity. Upon activation, CD161 stimulates specific acid sphingomyelinase/SMPD1, resulting in a significant increase in intracellular ceramide levels. The activation process also leads to the stimulation of AKT1/PKB and RPS6KA1/RSK1 kinases, along with a marked enhancement of T-cell proliferation induced by anti-CD3. Functioning as a lectin, CD161 binds to the terminal carbohydrate Gal-alpha(1,3)Gal epitope and the N-acetyllactosamine epitope. Furthermore, it acts as a ligand for CLEC2D/LLT1, inhibiting NK cell-mediated cytotoxicity and interferon-gamma secretion in target cells. Existing as a homodimer with disulfide linkage, CD161 interacts with acid sphingomyelinase/SMPD1, contributing to its multifaceted regulatory functions in immune responses.

Molecular Weight

55-70 kDa

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

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
