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) or 20-mer (G4S) 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).\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: All\nSENSITIVITY: Transfected Only\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800291299497,"sku":"71645S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-71645s","provider":"Iright","version":"1.0","type":"link"}
