Summary

A simple method for purification of human prothrombin from ACT) plasma of one single individual is described. This method is based on three steps :

1. isolation of crude prothrombin complex by barium citrate adsorption;

2. first purification by hydroxyapatite chromatography;

3. further purification by DEAE Sephadex chromatography.

The final product was obtained with a good yield and exhibited less than 5 p. cent contamination. The human purified prothrombin obtained in this way displays :

– one single chain by SDS electrophoresis,

– a molecular weight of 75,000-80,000 daltons,

– a pi value pH 4.4 by electrofocusing,

– Alanine as थ terminal residue.

Amino-acid analysis is reported.
