Isoelectric point markers for gel isoelectric separation

摘要

Isoelectric point markers for a gel isoelectric separation are prepared to comprise at least two colored proteins of which the isoelectric point pHs are known and wherein the difference between the highest value and the lowest value among the said pHs is not less than 0.5. The markers are applied to analyze proteins in a gel isoelectric separation method. The method employing the said markers makes it easy to analyze proteins and shows an excellent performance.
