DNA, MB Grade from fish sperm is a ready-to-use formulation of DNA that is already fragmented and denatured. The fragment length cannot be given exactly but is in the range (in form of a Gaussian distribution) of 100-3000 bp with a peak around 500-800 bp.

In contrast, DNA, Sodium Salt from fish sperm is a native formulation of DNA. During the isolation process, the native genomic DNA is likely to be broken down to smaller fragments of undefined length. Roche has however not determined the resulting fragment sizes. To be used as competitor DNA, this product should always be sonicated first. After sonification, the average fragment length is roughly the same as that for the MB-grade DNA, i.e., around 100-3000 bp. The values for average fragment sizes will depend on the respective sonification procedure. The procedure Roche uses for the MB-grade formulation results in an average chain length of 100-3000 bp, but more prolonged treatment may result in shorter fragments.", "Name": "Background Information - Help Corner" }, { "Language": "en", "Value": "This DNA preparation can serve for prevention of nonspecific binding in hybridization experiments.", "Name": "Positioning" }, { "Language": "en", "Value": "The DNA is sonicated.
