Abstract
A series of basic proteins, rich in proline, were isolated from the salivary secretions of humans and rats. These proteins underwent metachromasia after staining with Coomassie brilliant blue R-250 in sodium dodecyl sulfate-polyacrylamide gels. The technique of destaining gels in several changes of 10% acetic acid after a 30-min staining period is a rapid method of general utility for the identification of proline-rich proteins from total cell lysates from other sources besides saliva.
