FITC-Labeled Human CD8 alpha&beta (CD8A&CD8B) Heterodimer Protein, His Tag&Tag Free | CDA-HF2W4-25ug| Gentaur Distribution US, UK & Europe

Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. CD8A forms disulfide-linked heterodimers with CD8B at the cell surface. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells. Additionally, CD8B plays a critical role in thymic selection of CD8+ T-cells. A palmitoylation site in the cytoplasmic tail of CD8B chain contributes to partitioning of CD8 into the plasma membrane lipid rafts where signaling proteins are enriched.

Source: 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).

Format: Powder.

Tag: C-10×His | Native.

Expression System: HEK293.

Expression Region: Ser 22 - Asp 182 (CD8A) & Leu 22 - Pro 170 (CD8B).

Conjugate: FITC Labeled.

Molecular Weight: 19.5 kDa (CD8A) & 22.1 kDa (CD8B).

Characteristics: 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).

Purity: 90%.
