     218 linker FACS

    Flow cytometric analysis of Anti-BCMA (C11D5.3) CAR 293 cells staining with Alexa Fluor 488-Labeled Monoclonal Anti-Whitlow 218 linker Antibody, Rabbit IgG (P3C09) (0.03% Proclin) (Cat. No. 218-AFFMY3) at 1:25 dilution (4 μL of the antibody stock solution corresponds to labeling of 1e6 cells in a final volume of 100 µL). Alexa Fluor 488 signal was used to evaluate the binding activity (QC tested).

    Protocol
  •  218 linker FACS

    Non-specificity of Alexa Fluor 488-Labeled Monoclonal Anti-Whitlow 218 linker Antibody, Rabbit IgG (P3C09) (0.03% Proclin) (Cat. No. 218-AFFMY3) binding to CD3+ cells present in human PBMC. 5e5 of human PBMCs were simultaneously stained with PE-labeled anti-CD3 antibody and Alexa Fluor 488-Labeled Monoclonal Anti-Whitlow 218 linker Antibody (4 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 Alexa Fluor 488 and PE positive signals was used to evaluate the non-specific binding activity to human CD3+ cells (QC tested).

背景介绍

The whitlow/218 linker, with the sequence GSTSGSGKPGSGEGSTKG, is a commonly used synthetic peptide linker. Whitlow/218 linker often leveraged to connect the variable heavy (VH) domain and variable light (VL) domain of single-chain variable fragments (scFvs) and chimeric antigen receptors (CARs) that utilize an extracellular domain scFv for target antigen recognition. The scFv containing the 218 linker showed reduced aggregation and was found to be more stable to proteolysis in vitro.
