Abstract
|
|
|
For selective purification of proteins in Pleurotus cornucopiae, affinity chromatography was performed by p-aminoanilinylsuccinyl-AH-Sepharose 4B gel synthesized by treating p-phenylene diamine with succinyl-AH-Sepharose 4B, which was prepared by treating AH-Sepharose 4B with succinic anhydride. The capacity of p-aminoanilinyl ligand group was 6.1 micromole per milliliter of gel. Total apparent molecular weight of the affinity proteins eluted from the synthesized gel was 167 KD, which were a protein complex of 130 KD and 37 KD.
The contents of the nonpolar, polar, positively and/or negatively charged amino acids in the affinity protein were 44.57%, 24.75%, 21.25%, and 9.43%, respectively. Total apparent molecular weight of the affinity proteins eluted from the AH-Sepharose 4B gel was 95.2 KD, which were a protein complex of 61 KD, 31 KD and 3.2 KD. The contents of the nonpolar, positively and/or negatively charged amino acids in the affinity protein by AH-Sepharose 4B gel were 44.05%, 29.13%, and 12.91% respectively.
