OBJECTIVE: To study the method for rapid preparation of the gene chip probes for Bacillus anthracis protective antigen (pag).
METHODS: According to the sequences of pag published on PubMed, a pair of primers was designed to amplify the PA gene of Bacillus anthracis. Restriction enzyme digestion and AT clone were employed to rapidly screen out the recons of PA segments for the preparation of the gene chip probes. The DNA sequences of these segments were determined with 377 DNA Sequencer, and the resultant sequences analyzed with Bioinformatic software.
RESULTS: With the designed primers, the pag 2,205 bp in length was amplified. After enzyme digestion and AT clone, 7 fragments of varied lengths were screened, which underwent analysis with the basic local alignment sequence tool (BLAST) and 377 DNA Sequencer. BLAST analysis showed that all the fragments cloned belonged to Bacillus anthracis.
CONCLUSION: PCR in conjunction with restriction enzyme digestion and AT clone is rapid and simple to prepare the desired gene chip probes.
