PreparationofSonicatedHumanDNA
Purpose:To break up high molecular weight human placental DNA into fragment sizes of 500 bp or less which can be used as competitor DNA in Southern and in situ hybridizations. This method can also be used for sonicating salmon sperm DNA.Time required:2 hours for the sonicationSpecial reagents required:human placental DNA (Sigma, Cat.# D 4642)Special equipment required:A sonicator set up with a micro-tip. This method ......阅读全文
