UltraPure™ Salmon Sperm DNA Solution

UltraPure™ Salmon Sperm DNA Solution is a ready-to-use, sheared DNA solution that is used directly in the preparation of prehybridization and hybridization solutions. This DNA solution is prepared from highly pure, phenol/chloroform-extracted DNA and DNase-free, RNase-free (DEPC-treated), distilled, deionized water. The DNA is sheared to an average size of ≤2,000 bp. The concentration is adjusted to 10 mg/mL.

Applications
Such solutions are used to block the nonspecific attachment of probe to the surface of a membrane.

Performance and quality testing
Concentration, size verification, viscosity, and ultraviolet absorbance (A₂₆₀/A₂₈₀) are analytically tested.
