Abstract:
Streaking is a severe problem when narrow range basic immobilized pH gradient strips are used as the first dimension of two-dimensional (2-D) electrophoresis. It is demonstrated that this cysteinyl related streaking is eliminated when focusing is done in the presence of hydroxyethyl disulfide (DeStreak). Use of DeStreak also results in 2-D maps with simplified spot patterns and improved reproducibility.
