Contents |
August 20
- Joe:
- gel 167 - RFP pcr good, gel purify
- Digestions: SBP(SpeI/PstI), RFP(XbaI/PstI)
- Ligation of two digestions
- Michelle:
- Western blot transfer continued from 8/17 for samples of small colony from transformation of M2-BL21 developed :::membrane.
- Justin and Dafne:
- Large scale expression (200ml) of L-arabinose induced SBP-B12 protein with 5 nM vitamin B-complex
- Jeremiah & Chris:
- Western blot protocol (BL21 cells with no thiamine added)
- Run time points on a polyacrylamide gel (BL21 cells with thiamine added)
August 21
- Michelle:
- Western blot transfer of remaining supernatant from last Western blot transfer of small colony from transformation :::of M2-BL21.
- Justin and Dafne:
- Obtain protein from cells as done before
- Purify protein using Ni-NTX nickel column (per protocol)
- Analyze using western blot and coomassie brilliant blue
- Jeremiah & Chris:
- Western blot development (BL21 cells with no thiamine added)
- No band appeared after development so IPTG promoter could be the problem (picture on iphone)
- Cancel other expression attempt using IPTG and added thiamine
- Attempt to express our gene by use of a TET promoter
- Set up phusion PCR for the TBP+ gene
August 22
- Joe:
- Colony PCR - gel 171 right side both colonies good
- Michelle:
- Western blot transfer continued from yesterday for remaining supernatant sample for small colony from transformation :::of M2-BL21. Membrane developed.
- Cultured more M2-BL21 with LB AMP-CM.
- Jeremiah & Chris:
- Ran gel of phusion PCR products to confirm existence (gel #169)
- Purify gene using glass milk protocol
- Ran gel to see concentration (gel #170)
- Ligate phusion products together
- Expression plasmid phusion product already don
