Week 1 May 2 - 8 2011

Week 2 May 9 - 15 2011
Week 3 May 16 - 22 2011
Ryan vacationing in Whitefish. Having an awesome time.
Week 4 May 23 - 29 2011
First week Ryan begins working full time in the lab. Successfully used PCR to alter prefix and suffix regions to to the Silver standard for the genes xylE and mms6. That way we can fuse signal sequences. On an agarose gel the DNA strands are of expected size for both xylE and mms6 with the fusion standard. After attempting to cut PCR products of xylE and mms6 and cloning into psb1c3 using red/white screening, no white colonies test positive for the product when the plasmids are restricted and resolved on a gel. Miscellaneous plasmids are taken out of the glycerol stock and grown in LB cultures.
Week 5 May 30 - June 5 2011
The problem with the ligation of PCR products into psb1c3 is diagnosed as a result of prefix and suffix restriction sites being too close to the ends of the PCR products. Instead of using red/white colony screening and psb1c3 the polymerase used in the PCR produces blunt ends and therefore blunt end ligation is used for cloning with puc19. Different conditions are used in the blunt end ligation. Since puc19 has to be cut bluntly half the samples have the blunt end restriction enzyme heat killed. Blue/white colony screening has to be used in for puc19 cloning which requires X-Gal and IPTG. Solutions of these are made for the plates. Attempts to assemble miscellaneous parts from synthesis vectors to psb1c3 results in positive testing white colonies on an agarose gel for k331025, an enhanced cyan fluorescent protein with a ribosomal binding site and a c-terminally fused arginine residue tail. One colony for the blunt end ligation cloning of an xylE PCR product produces a band at the expected size when the plasmid is restricted and run on a gel. Attempts to move the remaining miscellaneous parts into psb1c3 produce no positive testing white colonies.
Week 6 June 6 - 12
A glycerol stock of the one colony of xylE and k331025 were made after they were re-transformed and grown in liquid LB culture. After another attempt the mms6 PCR product still refuses to be cloned via blunt end ligation. The same can be said for the another assembly of the miscellaneous parts to psb1c3.
Week 7 June 13 - 19
While these other aspects continue to elude success a plasmid preparation of SO4261, the ten residue arginine tag, is transformed and a glycerol stock of it is made is made.
