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.
