p-Hydroxyphenyl Glyoxal

Description

General Description

p-Hydroxyphenylglyoxal (HPG) is a protein modification reagent that reacts with arginine residues to give a large increase in absorbance at approximately 340 nm. HPG is a better choice for amino acid side chain modification due to its increased water solubility over phenylglyoxal and HPG modifier-associated improved oxidation resistance over p-nitrophenylglyoxal.
