- This DNA preparation can serve for prevention of nonspecific binding in hybridization experiments.
- Use this preparation of single-stranded genomic DNA fragments to prevent nonspecific binding in membrane or in situ DNA hybridization experiments. It can be added directly to the hybridization mix with no need for prior sonification or denaturation.
The DNA is sonicated. The length of the DNA fragments is mostly in the range of 50 to 600 bp (not verified). UV absorption maximum is at 258 nm.
