Fmoc-PEG3-Ala-Ala-Asn(Trt)-PAB-PNP is a peptide reagent for ADC conjugation that possesses a cleavable peptide sequence. The hydrophilic PEG spacer increases solubility in aqueous media.
Fmoc-PEG3-Ala-Ala-Asn(Trt)-PAB is a cleavable three-unit polyethylene glycol (PEG) linker employed in the synthesis of antibody-drug conjugates (ADCs)[1].
Azido-PEG4-Ala-Ala-Asn(Trt)-PAB is a PEG derivative conjugated with a peptide via an amide bond. The azide group on the PEG end enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media.
