Hello,
I get a 5g bottle of CYTOP from sigmaaldrich. Because it's my first time to use
CYTOP, I'm not sure whether it can be directly used to spin coat.I'm not sure
whether I have to dilute it with certain chemical or not, because the amount of
an order is just 5 gram, which is about 2.5mL. Below is information of my CYTOP,
from sigmaaldrich website.
Thanks.
