am·yl

(ā'mil),
The radical formed from a pentane, C5H12, by removal of one H. Several isomeric forms exist, the more important being CH3CH2CH2CH2CH2- (amyl or pentyl); (CH3)2CHCH2CH2- (isoamyl or isopentyl); CH3CH2CH2CH(CH)3- and (CH3CH2)2CH- (secondary amyl or pentyl); and CH3CH2C(CH3)2- (tertiary amyl or pentyl).
Synonym(s): pentyl (1)

7) The above supernatant containing DNA was treated with equal volume of isoamyl alcohol at -20degC for 12 h
After the lysis step, DNA was purified with phenol: chloroform: isoamyl alcohol (25:24:1) and in later the aqueous phase was treated twice time with phenol: chloroform (25:24) to purify the genomic DNA (Table 1).
