Product Description
Human CD3ζ (R52-R164)-3xG4S Recombinant Protein Quantitative Control is derived from a recombinant expression construct with CD3ζ (R52-R164) and 15-mer (G4S)3. The protein can be used with PathScan® RP G4S Linker/CD3ζ CAR Sandwich ELISA Kit #20418 and G4S Linker/CD3ζ CAR Matched Antibody Pair #81909 as a quantitative control. Suitable for use in other G4S Linker/CD3ζ assays when a control is needed.
| MW (kDa) | 28 |
| Purity | Assessed to be >93% by densitometry using SDS-PAGE analysis and Coomassie Blue detection. |
Background
The poly-Glycine-Serine (G4S) linker is a type of flexible, unstructured synthetic peptide linker sequence 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 linker itself consists of a core pentapeptide sequence, Gly-Gly-Gly-Gly-Ser, that is repeated and commonly found as either a 15-mer (G4S)3 or 20-mer (G4S)4 within scFv-based CARs and scFv fragments. The linker sequence length plays a role in controlling scFv stability and the noncovalent association between the VH and VL domains (1,2).
