Mal-Acetyl-Beta-Ala-Gly-Gly-Phe-Gly-PAB(m-PEG8)-PNP azide-dap-m-PEG4 SiR-NHS is the NHS ester

SiR-NHS is the NHS ester of SiR-6-COOH (652Ex/674Em) and can be conjugated to amine-containing molecules easily

which reacts with benzylguanine (BG)or chloropyrimidine (CP) derivatives

emitting in the red spectrum

connected by a flexible polyethylene glycol (PEG) linker

Mal-Acetyl-Beta-Ala-Gly-Gly-Phe-Gly-PAB(m-PEG8)-PNP azide-dap-m-PEG4 SiR-NHS is the NHS esterSOLU KNEX cleavable linker features a Gly Gly Phe Gly (GGFG) peptide. In this product, m PEG8 is attached to the commonly used self immolative para aminobenzyl (PAB) moiety to increase aqueous solubility. The PNP (para nitrophenyl) moiety serves as an activating leaving group, enabling efficient and selective conjugation of the payload to the linker. Derived from established ADC linker architectures, SOLU KNEX ADC linkers integrate solubilizing
