Recombinant Protein;25UG;FITC-Labeled Human CD8A&CD8B Heterodimer Protein, His Tag&Tag Free (CDA-HF2W4) is expressed from human 293 cells (HEK293). It contains AA Ser 22 - Asp 182 (CD8A) & Leu 22 - Pro 170 (CD8B) (Accession # P01732-1 (CD8A) & P10966-1 (CD8B)). It is the FITC labeled form of Human CD8A&CD8B Heterodimer Protein, His Tag&Tag Free (CDA-H52W5).;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).;Measured by its binding ability in a functional ELISA.
