<h2>Procedures for Isolation</h2> | <h2>Procedures for Isolation</h2> | ||
- | < | + | <ul><li>The LB Media should be transferred to 1.5 ml centrifuge tubes.</li> |
- | + | <li>These tubes are then centrifuged at 13,000 rpm for 10 minutes at room temperature.</li> | |
- | + | <li>After the centrifuge, the supernatent should be disposed without taking any pellets along with it.</li> | |
- | + | <li>The pelleted cells should be suspended in 250 ul Resuspension Solution and the tubes should be vortexed so that no cell clumps remain.</li> | |
- | + | <li>250 ul Lysis Solution is added. The tubes are inverted 4-6 times but the inversion shouldn't be done really fast as the Lysis Solution must not be shaken. Also it is smart to heat the Lysis Solution in order to ensure that no pericipitate remain.</li> | |
- | + | <li>350 ul Neutralization Solution should be added and the tube should be inverted immediately and throughly by inverting 4-6 times.</li> | |
- | + | <li>Centrifuge for 5 minutes to pellet cell debris and chromosomal DNA.</li> | |
- | + | <li>Transfer the supernatent to a spin column without taking any of the pellets.</li> | |
- | + | <li>Centrifuge the spin column for 1 minutes and discard the liquid at the bottom. Place the column at the same tube again.</li> | |
- | + | <li>Add 500 ul Wash Solution and centrifuge for 30-60 seconds. Discard the flow-through and place column back in.</li> | |
- | + | <li>Repeat the same process again with 500 ul Wash Solution.</li> | |
- | + | <li>Centrifuge for an additional 1 minute.</li> | |
- | + | <li>Transfer the columns into 1.5 ml microcentrifuge tubes and leave their caps open for 2 minutes so that the ethanol that they contain dissolves in air.</li> | |
- | + | <li>Add 50 ul Elution Buffer to the center of the silica membrane to elute the plasmid DNA. The pipette tip shouldn't the membrane. Incubate for 2 minutes and centrifuge for 2 minutes afterwards.</li> | |
+ | <li>Discard the spin column and store at -20 C.</li></ul> | ||

<h2>Digestion Protocol</h2> | <h2>Digestion Protocol</h2> | ||
- | < | + | <ul> |
- | + | <li>Take the average of the nucleic acid concentrations measured by the spectrometer.</li> | |
- | + | <li>Divide 500 by the DNA average.</li> | |
- | + | <li>Add 5ul Ne Buffer.</li> | |
- | + | <li>Add 0.5ul BSA Buffer.</li> | |
- | + | <li>Add 1 ul of the enzymes with barrier tips.</li> | |
- | + | <li>If you cut with EcoR1 and SpI, it will be up stream.</li> | |
- | + | <li>If you cut with Xbal and Pst1, it will be down stream.</li> | |
- | + | <li>Subtract the amount of DNA from 42.5 ul. This result will be the amount of NFW used.</li> | |
- | + | <li>Add the NFW with barrier tips and do one pippetting while taking the NFW.</li> | |
- | + | <li>Then the DNA is put into the PCR and is left there for 30 minutes.</li></ul> | |
