KIR3DL3/CD158z Protein, Human (HEK293, His)

KIR3DL3/CD158z, on natural killer cells, potentially inhibits NK cell activity, contributing to the prevention of cell lysis. This regulatory role underscores the significance of KIR3DL3 in modulating NK cell functions and maintaining immune homeostasis. KIR3DL3/CD158z Protein, Human (HEK293, His) is the recombinant human-derived KIR3DL3/CD158z protein, expressed by HEK293 , with C-His labeled tag. The total length of KIR3DL3/CD158z Protein, Human (HEK293, His) is 297 a.a., with molecular weight of 40-50 KDa.

KIR3DL3, present on natural killer cells, acts as a receptor that potentially inhibits NK cell activity, thereby contributing to the prevention of cell lysis. This regulatory role underscores the significance of KIR3DL3 in modulating the functions of NK cells and maintaining immune homeostasis.

Measured by its binding ability in a functional ELISA. Immobilized Human HHLA2 at 0.5 μg/mL (100μL/well) can bind Biotinylated human KIR3DL3. The ED₅₀ for this effect is 39.78ng/mL.

Approximately 40-50 kDa due to the glycosylation.

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder.

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

<1 EU/μg, determined by LAL method.

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).

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.

Room temperature in continental US; may vary elsewhere.
