CD8A-CD8B Heterodimer Protein, Human (HEK293, His, Flag)

Measured by its binding ability in a functional ELISA. Immobilized Human CD8A&CD8B, His Tag at 2μg/ml (100μl/well) on the plate can bind Anti-CD8 Antibody, hFc Tag. Test result was comparable to standard batch.

P01732(S22-D182)&P10966(L22-P170)

Predicted band size: 23.54 kDa; Observed band size: 26-28 kDa. (CD8 alpha) and 28-32 kDa. (CD8 beta)

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

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 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 from date of receipt. 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.
