Recommended Use
ACS grade formamide is suitable for blot washing procedures to remove background
hybridization.
Storage
ACS grade formamide is packaged under nitrogen. Store at +4oC in the dark. Warm to room
temperature prior to opening. When exposed to oxygen, formamide breaks down into formic
acid and ammonia, which can degrade nucleic acid samples. Bottles that have been opened
and stored should be deionized prior to use by mixing 1 g of mixed bed resin per 10mL
formamide for 30 minutes.
Warning
Irritant/Lachrymator/Suspected mutagen. Avoid breathing fumes. Use with adequate
ventilation. Avoid contact with eyes, skin and clothing. If contact should occur, wash
with copious amounts of water. See Material Safety Data Sheets for additional information.
