Abstract
Currently used elution methods for strong cation exchange (SCX) chromatography are based on two principles: salt and pH gradient. In this paper, we report the first observation of peptide elution by acid gradient. The degree of peptide separation using C18-SCX StageTip was greatly improved by our acid and salt-based elution method compared with a salt-based elution method. This development enabled us to identify over 22 000 phosphopeptides from 2 mg of protein without labor-intensive sample preparation. Our method is simple, robust, scalable, and low-cost and can be easily implemented without any special equipment or techniques.Entities:
