Notebook

Introduction

This page documents all the experiments we carried out in the wet lab as a part of our project. The details of the process we carried out can be found on our protocols page, and the chemicals we used can be found on the chemicals page. The interlab project was carried out alongside the rest of the wet lab but we have recorded it separately.

Interlab

Day 1

Transformed the 5 interlab parts into DH5a as per the transformation protocol.

Day 2

Transformations mostly unsuccessful. Started making new competent cells.

Day 3

Second day of competent cell preparation, cells frozen and put in the freezer.

Day 4

LB media preparation and re-transformation of the interlab parts.

Day 5

Had colonies from all interlab parts except PC. Picked colonies from all successful plates. Retransformed PC.

Day 6

PC didn't transform again. After measuring the sample we were sent with nanodrop we found the sample has no DNA in it. Requested a second sample from iGEM HQ Nevertheless we did a third transformation for PC. NC and TD1-3 were miniprepped and sent for sequencing.

Day 7

TD1 sequencing successful, others had the wrong part in so retransformed these. PC colonies successful despite nanodrop so picked colonies for these.

Day 8

PC miniprepped, digested and sent for sequencing. Colonies picked for re-transformed TD2, TD3 and NC.

Day 9

PC sequencing unsuccessful. TD2, TD3 and NC miniprepped and sent for sequencing.

Day 10

TD2 sequencing successful, others not. PC, NC and TD3 transformed again

Day 11

PC, NC and TD3 colonies picked.

Day 12

PC, NC and TD3 miniprepped and sent for sequencing.

Day 13

NC and TD3 sequencing successful but PC wrong so retransformed again.

Day 14

Picked colonies for PC.

Day 15

PC was miniprepped and digested. Gel showed it contained the wrong part so we transformed the part from the distribution kit instead.

Day 16

Colonies picked for PC.

Day 17

PC miniprepped, digested and sent for sequencing. Produced more competent cells.

Day 18

PC sequencing correct! All 5 interlab parts were transformed into MG1655

Day 19

Made the calibration curves for the OD600 and the FITC standard curve Colonies picked for all the interlab parts.

Day 20

Tested iGEM's protocol for the OD600 and the fluorescence. Picked more colonies for all 5 parts.

Day 21

Repeated iGEM's protocol and started Oxford iGEM's protocol.

Day 22

Finished Oxford iGEM's protocol and submitted the data obtained using iGEM's method to iGEM
