Team:Leicester/September2012

(09:00 am) The group returned to labs in the hope that the growth curve had gone right this time. However as per usual there was too much growth over the whole weekend. Some colonies could be counted but the group decided to wait for the rest of the team to return from their homes after going home for the weekend.

(09:15 am) The group worked on the wiki writing the past weeks work in, making sure all the details were correct and in the right order.

(11:00) Nathan and Chris went to the lab and started to work out the concentrations of the 16s extracted DNA to run on the gel, ready for sequencing. We don't want to use up to much of our DNA so needed to work out the optimum amount to run on the gel. As well as that we are going to have to remake the gel as the one will made has a fair few imperfections just to be on the safe side

(14:00) Calculations done, took some time as Chris had a meeting at 12 for a hour and a half. Had it checked and now are going to get ready to run 2ul of each of our sample, and 4ul of sample number 2 which has a lower ng/ul reading. As we have only a finite amount of DNA we are to vary the amount of the markers for different conc of DNA to work out the concentration of our samples to make sure the nano-drop was accurate. After this we can get ready to sequence the DNA to find out what the bacteria is.

(15:45) Nathan loaded the gel and then put the gel lane organisation

Gel is now running, and will be complete in 1 & 1/2 hours time.

(16:30) Group meeting to bring our supervisors up to speed with the project progress, and discuss terms and action plan for the following day, as well as a minor look into future plans.

(09:00) The group running the growth curve experiment had a single important task to do this morning. That being to plate out 2 colonies on a plate each to see if they are 2 forms of the same bacteria or simply 2 bacteria. This required plates being made, then individual colonies picked out to streak them. Once finished it is a day working on modelling, writing protocol and other computer based stuff before checking the results of the plates in the late afternoon.
