Gosh Laurey, we somehow got about five of the kits with our DE.str! I
didn't know how rich I was! I make them up and freeze 5 ul aliquots in 35%
ACN. That way one kit lasts 4-6 months. You are right about making them up
yourself and we do that too, but considering the time and effort to adjust
the concentrations if you want equal peak heights, and the inevitable
waste, it may not be worth it. However, I probably wont buy the kit when my
stocks run out. Thanks.
P.S. beautiful weather here now. Sunny and springtime cool.
regards,
Gary
