Active Recombinant Human CD8A&CD8B protein, His-tagged, FITC-Labeled

• Cat.No.: CD8A&CD8B-3012H
• Product Overview: FITC-Labeled Recombinant Human CD8A&CD8B protein(Ser 22-Asp 182 (CD8A) & Leu 22-Pro 170 (CD8B)), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Anti-CD8 alpha Antibody, Mouse IgG2a (clone: OKT8) at 1 μg/mL (100 μL/well) can bind FITC-Labeled Human CD8A&CD8B Heterodimer Protein, His Tag&Tag Free with a linear range of 0.625-2.5 μg/mL.
• Molecular Mass: FITC-Labeled Human CD8A&CD8B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of CD8 alpha and CD8 beta, has a calculated MW of 19.5 kDa (CD8 alpha) and 22.1 kDa (CD8 beta). Subunit CD8 alpha is fused with a polyhistidine tag at the C-terminus and subunit CD8 beta contains no tag. As a result of glycosylation, the heterodimer protein migrates as 30-32 kDa and 32-34 kDa under reducing (R) condition, and 30-33 kDa and 60-65 kDa under non-reducing (NR) condition (SDS-PAGE).
• Protein Length: Ser 22-Asp 182 (CD8A) & Leu 22-Pro 170 (CD8B)
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at-20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after storage 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.
