Dear CCP4 users, I'm sorry for non-ccp4 question. My lab is using protein crystalization screening from Hampton and Emerald. However I noticed the Expires Date was 05/2002. That means we are using the too old chemical. Could I ask your experience about this problem? Should I need to remove these expired screening because we still have many stocks. Thank you for your reply.
My best regards, TriNgo PhD Student, Sungkyunkwan University
