Re: 2.5 M glycine crystallized

It's normal for some things to crystallize out of aqueous solution, especially at reduced temperatures. Apparently glycine is such a molecule. Storage at room temperature might prevent the crystallization, but you might also get microbial growth if there are any critters in there. ...

Then I use PH2.2 Glycine + tween20 to disable the first AB and wash many times. Then I add the second AB, anti-Fluorescein-POD, and couple it with fluorescein TSA....No ...
