Development of a quantification method based on isotopic variants of O-methyl isourea (OMIU) in conjunction with reversed-phase (RP) liquid chromatography (LC) electrospray mass spectrometry is descri...

Chemical modification of bovine pancreatic trypsin inhibitor for single site coupling of immunogenic peptides for NMR conformational analysis.

J. Biol. Chem. 264(14) , 7882-8, (1989)

Procedures for chemical modification of bovine pancreatic trypsin inhibitor (BPTI) to allow site-specific coupling of immunogenic peptides are reported. Each of the modified proteins has a single free...

Chemical modulation of the chaperone function of human alphaA-crystallin.

J. Biochem. 144(1) , 21-32, (2008)

alphaA-crystallin is abundant in the lens of the eye and acts as a molecular chaperone by preventing aggregation of denaturing proteins. We previously found that chemical modification of the guanidino...
