Medchemexpress LLC Mal-amido-PEG10-C2-NHS ester | 1137109-22-8 | MFCD20226950 | >98.0% | 777.81 | C34H55N3O17 | 100 MG
Mal-amido-PEG10-C2-NHS ester is a non-cleavable ADC linker that contains a maleimide group and an N-hydroxysuccinimide (NHS) ester. The maleimide reacts with thiols, and the NHS ester reacts with primary amines, enabling conjugation to cysteine and lysine residues for protein, peptide, and oligonucleotide labeling.
- Non-cleavable linker with maleimide and NHS ester functional groups.
- Enables thiol (cysteine) and amine (lysine) conjugation chemistries.
- High purity suitable for bioconjugation and ADC synthesis.
- Available in small mg-scale pack sizes for research applications.
- Stable when stored frozen; follow SDS storage recommendations.
