tcep-biotin

TCEP-biotin is a biotinylated form of TCEP, serving as an affinity probe for lysine crotonylation in proteins. TCEP functions as a thiol reducing agent, quantitatively cleaving simple organic disulphides into thiols in aqueous solutions.

DBCO-S-S-PEG3-biotin is a cleavable reagent for the introduction of a biotin moiety to azide-containing biomolecules using copper-free Click Chemistry. The disulfide bond in this linker can be cleaved with reducing agents such as DTT, BME, and TCEP to remove the biotin label. PEG linkers can also be used in the synthesis of PROTACs.

Biotin-PEG4-SS-acid functions as a cleavable reagent designed to efficiently attach biotin to amine-containing biomolecules. The disulfide bond within this linker can be cleaved using reducing agents [such as DTT, BME, and TCEP] to remove the biotin label.
