Structural polypeptides of cholera bacteriophage

摘要

The structural polypeptides of the cholera bacteriophagehave been analysed by sodium dodecyl sulphate – polyacrylamide gel electrophoresis. Eight different polypeptides were identified. The apparent molecular weights of the polypeptides were 143 000, 96 500, 68 000, 53 000, 37 500, 29 500, 21 000, and 13 500, respectively. The percentage of total protein corresponding to each polypeptide was estimated.
