PCR Check and Third DNA Isolation of G.tigrina
We then measured out approximately 0.025g of G.tigrina - (whole organism will readily lyse in proteinase K and ATL buffer) - because this quantity is suggested by our DNA extraction kit, Qiagen DNeasy Blood & Tissue Kit - (for 20ul proteinase K and 180ul ATL buffer). This involved weighing out about 15-20 planarians, which is considerably more than we used for any previous extractions (1-2 organisms). The 0.025g sample was scraped into a 1.5mL tube with 20ul proteinase K and 180ul ATL buffer, vortexed, and placed into a 56°C water bath overnight. The sample will continue to be isolated and purified tomorrow, Wednesday 10/05/2011. | |
