  • 表达区间及表达系统(Source)

    PE-Labeled Human CD27 Ligand Protein, His Tag (CDL-HP246) is produced via conjugation of PE to Human CD27 Ligand Protein, His Tag with a new generation site-specific technology under Star Staining labeling platform. Human CD27 Ligand Protein, His Tag is expressed from human 293 cells (HEK293). It contains AA Ser 52 - Pro 193 (Accession # P32970-1).

    Predicted N-terminus: His

  • 蛋白结构(Molecular Characterization)

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 61.6 kDa.

  • 偶联(Conjugate)

    PE

    Excitation Wavelength: 488 nm / 561 nm

    Emission Wavelength: 575 nm

  • 内毒素(Endotoxin)

    FACS Analysis of Anti-CD27 Ligand CAR Expression

     CD27 Ligand CAR_T

    5e5 of anti-CD27 Ligand CAR-293 cells were stained with 100 μL of 1:50 dilution (2 μL stock solution in 100 μL FACS buffer) of PE-Labeled Human CD27 Ligand Protein, His Tag (Cat. No.CDL-HP246) and negative control protein respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A). PE signal was used to evaluate the binding activity (QC tested).

背景介绍

Cluster of Differentiation 70 (CD70) is also known as CD27 ligand (CD27L / CD27LG), TNFSF7, TNFSF7G, is a type II transmembrane glycoprotein belonging to the TNF superfamily (TNFSF) and is a surface antigen found on activated T-and B-lymphocytes and mature dendritic cells. Binding of CD70 to its receptor CD27 induces in priming, effector functions, differentiation and memory formation of T-cells, and thus is invloved in the biological processes including T-cell activation, the proliferation of costimulated T-cells, as well as the generation of cytolytic T-cells. CD70 on T cells provides costimulatory signals that are required for T cell proliferation, clonal expansion and the promotion of effector T cell formation. CD70 on mouse B cell has been shown to inhibit terminal differentiation of activated B cells into plasma cells and enhances commitment to memory B cell responses. CD70 induces proliferation and IFNγ production, on NK cells.
