Loopful of bacterial in a short time brought clear twice in PBS.Andresuspended in the extraction buffer (EB) 500 ul (10 mM Tris HCl, pH 8.0 –And 1 mM EDTA) tubes, microcentrifuge tubes put in and let heat for a period of 12 minutes in a water bath. in the case of frozen tissue of the spleen. Approximately 500 microliter of the homogenate by melt spinning leads to a short period of time, and resuspended in tissue pellet 500 EB microliter to make pure DNA extraction by phenol/chloroform/isoamyl alcohol followed by ethanol precipitation DNA genome transmission is measured using the Eppendorf spectophotometry. approximately 500-1000 NG to.Preparation of DNA is used as a template in the PCR reaction, DNA 16S rRNA which is used to distinguish the type of DNA isolated from bacteria, and the spleen the spleen homogenates of both 3-5 microliter of each DNA sample of MarF Primer (5 '-AGGACCACGGGATTCATGTCC-3 ') and Marr (5 '-GTAGGAGTCTGGGCCGTATCTCAG-3 ') in 25 litres micro-service interaction.Medicine PCR Taq DNA polymers using each reaction contained 200 mm 1.5 enzyme authority deoxynucleoside triphosphate, 2 mm MgCl2, and 10 pmol of each primer. As follows: 95° C for 5 min; 35° C 95° C around 55 to 72° C for 1 minute each time followed by a final extension at 72° c for 7 minutes, five of each microliter reaction mixture was analyzed on agarose gel ethidium 1.2% with layom bromide for display of product, there is no PCR template DNA negative control included with the work of each PCR method.
