Does expired human collagen(LYOPHILIZED) type IV work while coating plate?

03 April 2017 1 4K Report

The tube has net been opened yet.

How expired is it? It's condition may depend on the lyophylization process and subsequent storage conditions. Are you really asking if the collagen is broken down? If so perhaps run a gel to see degradation. Or you may wish to call the manufacturer for a degradation curve. If its home made lyophilizate, you can test to see if it works as a plate coating.
