ProteomicsIdentification of peptide isoforms in gS-crystallin using stable isotope labeled peptides
ɣS-crystallin is a major protein of the human lens and is highly modified with age and cataract due to a lack of lens protein turnover. Previous studies have identified some sites of isomerization and racemization of deamidated asparaginyl and aspartyl residues in ɣS but have been limited due to the...

ProteomicsAbsolute abundance of human crystallins in lens
Purpose: Measurement of crystallin abundances in human lens has previous relied on poorly reproducible electrophoretic separations or only semi-quantitative mass spectrometry. Therefore, isotope labeled standards were created for all major human lens crystallins so that their absolute abundances cou...
