Bromo-PEG2-C2-azide is a non-cleavable ADC linker employed in the synthesis of antibody-drug conjugates (ADCs)[1].

Sulfo-SPP is a heterobifunctional, thiol-cleavable, and membrane-impermeable crosslinker.

Gly-PEG3-amine is a cleavable three-unit PEG ADC linker that serves as a crucial component in the synthesis of antibody-drug conjugates (ADCs)[1].

Mal-PEG1-acid is a non-cleavable (1 unit PEG) ADC linker used in the synthesis of antibody-drug conjugates (ADCs)

Bis-PEG4-NHS ester is a noncleavable, 4-unit PEG linker used for antibody-drug conjugation (ADC).

DBCO-NHCO-PEG4-NH-Boc is a cleavable ADC linker employed in the synthesis of antibody-drug conjugates (ADCs) [1].

m-PEG7-CH2COOH is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs).

Bis-PEG13-NHS ester, a cleavable ADC linker, is utilized in the synthesis of antibody-drug conjugates (ADCs) [1].

Mal-amido-PEG1-C2-NHS ester is a noncleavable antibody-drug conjugate (ADC) linker that incorporates a maleimide functional group and an N-hydroxysuccinimide (NHS) ester. The NHS ester offers a means to specifically modify primary amines (-NH2) present in proteins, amine-modified oligonucleotides, and other amine-containing molecules[1][2].
