exchanger, has shown that 1 M sodium hydroxide combined with 1 M sodium chloride effectively removes DNA, but that the level of removal is dependent on the nature of the sample (6). The contact time for cleaning-in-place (CIP) in these experiments was 2 hours. For one sample, DNase was required to completely remove DNA from the anion exchanger.

General Protocol for Precipitation of DNA with Sodium ...

General Protocol for Precipitation of DNA with Sodium Acetate and Ethanol For ethanol precipitation of DNA from solution, the solution needs to have a high salt concentration. usually, this must be added in the form of sodium acetate (Na-Ac, the best salt for this purpose) or NaCl. After the solution has been adjusted with salt, 100%

The DNA is contaminated The aqueous phase is incompletely removed. Remove remnants of the aqueous phase prior to DNA precipitation. The DNA pellet is insufficiently washed with 0.1 M sodium citrate in 10% ethanol Make sure pellet is washed with 0.1 M sodium citrate in 10% ethanol. The DNA A260/280 ratio is low Phenol was not sufficiently removed

In situ hybridization protocol - Abcam

DNA probes provide high sensitivity for in situ hybridization. They do not hybridize as strongly to target mRNA molecules compared to RNA probes, so formaldehyde should not be used in the post hybridization washes. 3 ... To prepare 1 L of 20x saline sodium citrate (SSC)
