Purification of protein C a natural anticoagulant, from human plasma by affinity chromatography with Convanavalin A

Prep Biochem Biotechnol. 1996 Aug-Nov;26(3-4):183-8. doi: 10.1080/10826069608000064.


We have developed a rapid, efficient, and inexpensive method to purify protein C from plasma using Concanavalin A conjugated to Sepharose. With this method we have obtained protein C purified to homogeneity, as measured in polyacrylamide gels. We discuss each of the steps of our method and give the results of the purification.
