PD-L1 Protein, Mouse (239a.a, HEK293, Fc)

Cat. No.: HY-P73363
COA Handling Instructions

PD-L1 protein serves as a ligand for the inhibitory receptor PDCD1/PD-1 and is critical for maintaining immune tolerance. This interaction modulates T cell activation, limits effector responses and may stimulate IL10-producing T cell subsets. PD-L1 Protein, Mouse (239a.a, HEK293, Fc) is the recombinant mouse-derived PD-L1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of PD-L1 Protein, Mouse (239a.a, HEK293, Fc) is 239 a.a., with molecular weight of ~51.6 kDa.

Description

PD-L1 protein serves as a ligand for the inhibitory receptor PDCD1/PD-1 and is critical for maintaining immune tolerance. This interaction modulates T cell activation, limits effector responses and may stimulate IL10-producing T cell subsets. PD-L1 Protein, Mouse (239a.a, HEK293, Fc) is the recombinant mouse-derived PD-L1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of PD-L1 Protein, Mouse (239a.a, HEK293, Fc) is 239 a.a., with molecular weight of ~51.6 kDa.

Background

PD-L1 protein plays a crucial role in maintaining immune tolerance to self by acting as a ligand for the inhibitory receptor PDCD1/PD-1. This interaction modulates the activation threshold of T-cells, limiting their effector response and potentially stimulating T-cell subsets that produce interleukin-10 (IL10). However, tumors exploit the PDCD1-mediated inhibitory pathway to attenuate anti-tumor immunity and evade destruction by the immune system, thereby promoting tumor survival. The interaction between PD-L1 and PDCD1/PD-1 inhibits the function of cytotoxic T lymphocytes (CTLs), but blocking this pathway can reverse the exhausted T-cell phenotype and normalize the anti-tumor response, offering a promising strategy for cancer immunotherapy.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

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.

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
