INTERLAB

Our team participated in the Fifth International InterLaboratory Measurement Study this year. The interlab study aims to solve the problem of reliability and repeatability in synthetic biology study. This year we were asked to measure green fluorescent protein, which is used as a measurement marker. We followed the experiment protocol strictly to make sure our data is valid. After two weeks lab work, we got the data we need after several attempts.

Calibration Protocol

Three calibration measurement were done by the calibration protocol, including an OD reference point at 600nm, one particle standard curve and one fluorescent standard curve.

Transformation

Transform Escherichia coli DH5α with these following plasmids:

Device Part Number Location
Positive control BBa_R0040 Well 2D
Negative control Ba_I20270 Well 2B
Test Device 1 BBa_J364000 Well 2F
Test Device 2 BBa_J364001 Well 2H
Test Device 3 BBa_J364002 Well 2J
Test Device 4 BBa_J364007 Well 2L
Test Device 5 BBa_J364008 Well 2N
Test Device 6 BBa_J364009 Well 2P

The transformation used E.coli DH5α competent cells bought from Tsingke Biological Technology company, and follow the steps in http://parts.igem.org/Help:2017_DNA_Distribution to use the DNA in the Distribution Kit.
