B7-2/CD86 Protein, Human (Biotinylated, HEK293, His-Avi)

B7-2/CD86 protein negatively regulates T-cell activation by disrupting CD86 cluster formation, modulating the T-cell response, and influencing immune activation. B7-2/CD86 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived B7-2/CD86 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of B7-2/CD86 Protein, Human (Biotinylated, HEK293, His-Avi) is 222 a.a., with molecular weight of 55-70 kDa.

B7-2/CD86 protein functions as a negative regulator of T-cell activation by disrupting the formation of CD86 clusters. Through this interference, it modulates the T-cell response and plays a role in regulating immune activation.

Greater than 95% as determined by Tris-Bis PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 5% 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.
