Can anyone suggest me the best way to remove entrapped formic acid from silk fibroin hard gel? And how to quantify it?
I got these smeared bands quite often lately. We typically run the gel at 140V with a 10-12% gel and do a wet transfer at 220 mA for 1.5 hr in cold room. We also noticed some dirty spots/dots (see...
