A Simple and Rapid Extraction of High Molecular Weight Chromosomal DNA from Bacillus subtilis Protoplasts for Cosmid Cloning and Interspecific Transformation |
|
| Abstract: | After conversion of Bacillus subtilis vegetative cells to protoplasts, a simple and rapid method for extracting high-molecular-weight chromosomal DNA was devised with the inclusion of bovine serum albumin and phenol-chloroform treatments. The DNA sample thus prepared was the size of 100-450 kb and could be used for cosmid cloning and interspecific transformation. |
