How do you digest protein lysate?

Proteolytic digestion of a complicated protein mixture from an organelle or whole-cell lysate is usually carried out in a dilute solution of a denaturing buffer, such as 1-2 M urea. Urea must be subsequently removed by C18 beads before downstream analysis such as HPLC/MS/MS or complete methylation followed by IMAC isolation of phosphopeptides.
