Amino-PEG3-t-butyl ester is a PEG derivative containing an amino group with the t-butyl protected carboxyl group. The t-butyl protected carboxyl group can be deprotected under acidic conditions.
Fmoc-N-amido-PEG12-acid is a PEG derivative, it contains a Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. Under the basic conditions, the Fmoc group can be deprotected to obtain the f
Hydroxy-PEG12-t-butyl ester is a PEG derivative containing a hydroxyl group and a t-butyl ester. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Under acidic conditions, the t-butyl protected carbox
Azido-PEG2-t-butyl ester is a PEG derivative containing a t-butyl ester and an azide group. The hydrophilic PEG spacer increases solubility in aqueous media. Under acidic conditions, the t-butyl protected carboxyl group can be deprotected.
Exo-BCN-PEG2-Boc-amine is a PEG derivative containing a BCN group and a Boc-protected amine. PEG Linkers and PEG derivatives may be useful in the development of antibody-drug conjugates.
t-Boc-N-amido-PEG4-NHS ester is a PEG derivative containing an NHS ester and a Boc-protected amino group. The NHS ester can be utilized to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
