Active Recombinant Human CD8A protein, His-tagged

• Cat.No.: CD8A-3196H
• Product Overview: Recombinant Human CD8A protein(Ser 22 - Asp 182), fused with His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 22-182 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human CD8 alpha, His Tag at 5 μg/mL (100 μL/well) can bind Anti-CD8 alpha Antibody, Human IgG1 with a linear range of 1-2 ng/mL.Immobilized Anti-CD8 alpha Antibody, Mouse IgG2a (clone: OKT8) at 1 μg/mL (100 μL/well) can bind Human CD8 alpha, His Tag with a linear range of 0.6-10 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 19.5 kDa. The protein migrates as 26-32 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Ser22-Asp182
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.>90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
