Revision as of 09:23, 19 July 2013
Sander
prepared 20 tubes for use in -80 c Glyserol stock.
created a restriction digest reaction for silk.
| Sample | componant | volume (ul) |
| silk1 | silk | 5 |
| BamHI buffer | 2 | |
| BamHI enzyme | 0,5 | |
| BSA | 0,5 |
MilliQ was added to reach a 20 ul volume.
placed in incubater at 37,2 C at 17:10
Inne & Mirjam
Cells with BBa_k818000, inoculated overnight, were successfully grown.
Both negative controls were clear, and the rest of the samples was turbid.
Did a miniprep of the samples 1 & 2 (the ones with Amp).
| # | composition | Bacteria |
| 1 | 4mL LB 8uL Amp | + |
| 2 | 4mL LB 8uL Amp | + |
| 3 | 4mL LB 8uL Amp (negative control) | - |
| 4 | 4mL LB | + |
| 5 | 4mL LB (negative control) | - |
Afterwards concentration of DNA was determined via nanodrop.
Results: sample 1 = 60.1 ng/uL, sample 2 = 31.8 ng/uL
During the miniprep the filtered LB medium was poured back into the culture (so cells could grow again).
A -80 C stock was made with 1 mL culture (sample 1). (stored in tray: iGEM 2012 A, compartment 70)
Mirjam
A check of the RFP, YFP and GFP plates revealed that GFP did not grow on the plate. RFP and YFP colonies are inoculated in liquid LB medium with cm.
Also the new made transformation of the promoter in the backbone showed colonies.
A mini prep is done for RFP and YFP and the samples are stored in the freezer.
A PCR is made for all silk parts. Only the silk without strep tags showed a band at the expected height. Two samples are purified and checked on gel. It did show a band around 900 bp. Because of the low initial concentration, the samples are combined and concentrated to end up with a concentration of 19 ng/ul. This is a nice concentration to make a restriction digestion.
