Abstract

Isoelectric point (IEP) is one of the most important physicochemical properties of protein. There are many different methods for the determination of IEP. In this paper, a comparative study between the simplest turbidimetry/spectrometry method and the most advanced capillary IEP focusing (CaIPF) method was made. Henan cattle hide gelatin’s IEP was determined with the two methods and the advantages of the CaIPF method over the other methods were demonstrated and discussed.

Key words： Isoelectric point; gelatin; turbidimetry/spectrometry; capillary IEP focusing
