     G4S linker FACS

    Flow cytometric analysis of Anti-MSLN CAR-293 cells staining with FITC-Labeled Monoclonal Anti-G4S linker Antibody, Rabbit IgG (016) (Cat. No. G4S-FAFYP1) at 1:50 dilution (2 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL), compared with negative control. FITC signal was used to evaluate the binding activity (QC tested).

  •  G4S linker FACS

    Non-specificity of FITC-Labeled Monoclonal Anti-G4S linker Antibody, Rabbit IgG (016) (Cat. No. G4S-FAFYP1) binding to CD3+ cells present in human PBMC. 5e5 of human PBMCs were simultaneously stained with PE anti-CD3 antibody and FITC-Labeled Monoclonal Anti-G4S linker Antibody, Rabbit IgG (016) (2 μL of the antibody stock solution corresponds to labeling of 5e5 cells in a final volume of 100 µL) and washed and then analyzed with FACS. Both PE and FITC positive signals was used to evaluate the non-specific binding activity to human CD3+ cells (QC tested).

배경 소개

The G4S linker is emerged as the most common linking peptides for scFvs. It is composed of the repeated sequence (Gly-Gly-Gly-Gly-Ser) and commonly found as either a 15-mer (G4S)3 or 20-mer(G4S)4 within scFv fragments. The G4S linker has become an integral part of the vast majority of CARs as it links the VH and VL recognition domains of scFvs. The G4S linker is commonly used in CARs targeting solid tumor antigens, such as HER2 and CEA, while the whitlow/218 linker peptide is predominantly used in CAR constructs targeting hematological malignancies such as CD19 CAR products.
