  • HY-P72706
    CD81 Protein, Human (HEK293, Fc)

    CD81 antigen; CD81 molecule; CD81; CVID6; TAPA1; TAPA-1; TSPAN28

    		Human HEK293
    The CD19 receptor is critical for B cell activation, driving the trafficking and assembly of CD19-CR2 and BCR complexes, thereby lowering the antigenic threshold for B cell clonal expansion. In T cells, CD19 contributes to CD3 localization and influences polarization. CD81 Protein, Human (HEK293, Fc) is the recombinant human-derived CD81 protein, expressed by HEK293 , with N-hFc labeled tag. The total length of CD81 Protein, Human (HEK293, Fc) is 89 a.a., with molecular weight of ~37 kDa.

    CD81 antigen; CD81; CVID6; TAPA-1; TSPAN28

    		Mouse HEK293
    The CD81 protein has important effects on cellular processes and is involved in CD19 receptor trafficking on activated B cells. This facilitates CD19-CR2 and B cell receptor complex assembly, lowering the antigen dose threshold for B cell clonal expansion. CD81 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived CD81 protein, expressed by HEK293 , with N-mFc labeled tag. The total length of CD81 Protein, Mouse (HEK293, Fc) is 86 a.a., with molecular weight of ~36.1 kDa.

    CD81 antigen; CD81; CVID6; TAPA-1; TSPAN28

    		Rat HEK293
    CD81, a versatile protein, participates in complement-opsonized particle ingestion, inhibits osteoclast formation, and regulates compartmentalized enzymatic activities. In T cells, CD81 controls intracellular dNTP levels by localizing and degrading SAMHD1. Moreover, it influences cell adhesion and motility, notably in macrophages. CD81 Protein, Rat (HEK293, Fc) is the recombinant rat-derived CD81 protein, expressed by HEK293 , with N-mFc labeled tag. The total length of CD81 Protein, Rat (HEK293, Fc) is 86 a.a., with molecular weight of ~36.2 kDa.
