Description
Fmoc-PEG6-NHS ester is a PEG linker that features an Fmoc-protected amine along with an NHS ester. The hydrophilic PEG spacer enhances solubility in aqueous solutions. The Fmoc group can be removed under basic conditions to yield free amines, which are suitable for further conjugation reactions. This NHS ester can label primary amines t-found in proteins, amine-modified oligonucleotides, and other molecules containing amino groups.
