Low molecular weight herring sperm, salmon sperm or calf
thymus DNA is prepared by methods developed at Lofstrand Labs Limited.
High molecular weight DNA is hydrolyzed by controlled alkaline digestion
at reduced temperature.The product of this reaction is a DNA molecule
with an average size of 300-600 base pairs. Alkaline digestion results
in DNA cleavage at non-random sites, resulting in lower network formation
upon reannealing than is observed with DNA that has been sonicated or mechanically
sheared.Prehybe is ideally suited for the prehybridization of filters
used in "Southern" blotting procedures. Prehybe is available in four convenient
package sizes. Please indicate your required size at time of order.
