Experiment 4: Purifying/Digesting PCR Products
We used the 10 PCR samples from last week (Experiment 3: Large Quantity PCR) and purified them using GeneJET PCR Purification Kit. We proceeded by digesting the purified products with XBA1 and PST1. This will prepare our gene segment with the properly cut biobrick ends to be inserted into our vector plasmid. After the digestion, we purified the products to clean them of the enzymes and contaminants.
We are currently running gel electrophoresis to check if we have viable DNA segments. The samples we are testing are as follows: raw PCR product from experiment 3 (T1), purified PCR product (T2), purified digested PCR product (T3), and the negative/positive controls from experiment 3 (+/-).
We expect to see from: T1- Our PCR experiment worked correctly with our primers and still have the correct length of DNA (1044 bp plus biobricks). T2- How well the GeneJET kit worked in purifying our gene. T3- If our gene was properly digested with XBA1 and PST1 (it'll show as a slightly smaller band, ~10 bp shorter). +/- controls- Should be consistent with the gel results from experiment 1.
