I am planning to do a lot of ChIPs following 'Chromatin techniques for plant cells Bowler 2004' and thus I am planning on stockpiling a lot of stock solutions and premade ChIP buffers. I'm having a very difficult time finding any consistent info on storage conditions for even individual solutions and whether they should be sterile and whether to do it by autoclave or filter. Multiple sources give conflicting information so I've tried to compile what I felt was the consensus below.
I was wondering if I could get any help confirming that the below information is correct and fill in the missing info?
A: typical storage condition/time in storage
B: storable at -20C?/time stable at -20C
C: storable at -80C? /time stable at -80C
D: light sensitive?
E: should be autoclaved?
F: should be filter sterilized?
G: special considerations
