Formamide
is widely used for hybridizing and denaturing nucleic acids(1). To
be suitable for such applications, formamide must be highly
deionized and free of contaminants. Ultra Pure Formamide possesses a
high degree of purity and is free of contaminating RNase and DNase
making it the ideal choice for all molecular biology applications.
It is suitable for the preparation of hybridization cocktails and
various denaturing solutions used with nucleic acids. It will not
cause degradation of expensive or hard to isolate RNA and DNA
samples. Each lot of material is pre-filtered through a mixed-ion
exchange resin to eliminate products of decomposition and residual
metal cations. This filtering process guarantees that each lot has a
final purity of greater than 99.5% and an absorbance value of less
than 0.05 absorbance units at 280nm. Each lot then undergoes rigid
quality control testing to insure that assay specifications are met
prior to release.
