3-Methylbutyraldehyde-2,2-d2

Internal Standards for 2-D

Internal standards are extremely valuable for determining the pH and mol-wt ranges of a specific 2-D gel system and for constructing calibration curves for calculating the relative pI and M r of unknown proteins. Although external markers

Computer Analysis of 2-D Images

Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) images, when used to analyze protein expression in large sets of biological samples, are best processed by computer. In this manner, one can detect and quantify even the faintest

2-D Phosphopeptide Mapping

A major mechanism that cells use to regulate protein function is by phosphorylation and/or dephosphorylation of serine, threonine, and tyrosine residues. Phosphopeptide mapping of these phosphorylated residues allows investigation
