| Abstract: | An HPLC approach for purification and sequencing of double-stranded DNA obtained directly from a PCR is described. This simple and reliable procedure has several advantages; the DNA fragment is rapidly eluted (less than 7 minutes), requires no organic cleanup, produces several hundred bases of sequence and is sensitive enough to obtain DNA sequence from a single 100-microliters PCR. This method is demonstrated by sequencing tumor necrosis factor alpha (TNF alpha) gene amplified from mouse tail DNA. |
