KIR2DL5/CD158f 蛋白, Human (Biotinylated, HEK293, His-Avi)

KIR2DL5/CD158f, present on NK cells, acts as a receptor for HLA-C alleles. Its inhibitory function finely tunes NK cell activity, preventing cell lysis by interacting with specific HLA-C molecules. This dynamic engagement contributes to the nuanced balance of inhibitory signals in the immune system, regulating NK cell responses to potential targets. KIR2DL5/CD158f Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived KIR2DL5/CD158f protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of KIR2DL5/CD158f Protein, Human (Biotinylated, HEK293, His-Avi) is 219 a.a., with molecular weight of 45-55 kDa.

KIR2DL5/CD158f 在自然杀伤 (NK) 细胞上表达，充当 HLA-C 等位基因的受体。该受体以抑制方式发挥作用，调节 NK 细胞活性以防止细胞裂解。通过与特定的 HLA-C 分子相互作用，KIR2DL5 有助于免疫系统中抑制信号的微妙平衡，微调 NK 细胞对潜在目标的反应。

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

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

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.
