Team Accomplishments

CONTRIBUTIONS:

We participated in the InterLab study, which helped to reduce the lab-to-lab variability around the world. We also put forward new ideas of the tandem expression of chromoproteins, to get new colors, which would greatly enrich the colors and the BioBrick parts in the Registry. Then using the RGB system[1] which was central to our project, we characterized the Red-, Green-,Blue light sensors (Cph8, YF1, CcaSR) which had already existed in the registry(BBa_K1886006, BBa_K1053210, BBa_K2598005), by exploring the relationship between the fluorescent intensity with the wavelengths and intensity of input light.

INTERLAB

Summary

Interlab is a global collaboration through which the Measurement Committee aim to improve the measurement tools available to both the iGEM community and the synthetic biology community as a whole. This year, the Committee along with teams all over the world aimed to reduce lab-to-lab variability in fluorescence measurements by normalizing to absolute cell count or colony-forming units (CFUs) instead of OD.

Procedure

In order to compute the cell count in samples, two orthogonal approaches were exploited. (detailed protocol was provided in https://2018.igem.org/Measurement/InterLab/Plate_Reader)

  • Converting between absorbance of cells to absorbance of a known concentration of beads:

    • In this year’s Measurement Kit, we were provided with a sample containing silica beads that were roughly the same size and shape as a typical E. coli cell. As we knew the concentration of the beads, we could convert absorbance measurements into a universal, standard “equivalent concentration of beads” measurement.

  • Counting colony-forming units (CFUs) from the sample:

    • Since each colony began with a single cell, by counting the colonies cell numbers in certain volume of media could be determined. We were required to determine the number of CFUs in positive and negative control samples in order to compute a conversion factor from absorbance to CFU.

Software:

Our software was designed by Yun DONG and Shiyang WANG. The software was written by Shiyang WANG.

Modelling:

Our modeling work was mainly accomplished by Liangpu Wang, with the help of Shiyang WANG.

Human Practice:

Yun DONG is the leader of our HP Squad. She accomplished most of the contact and interview work and record every HP activity. Jiachen HU and Yaru TIAN made the educational videos. Yufei SHAN contacted the educational speech in the primary school and some meet-ups. Yuanli GAO, Ziyi ZHAO, Zepeng XU, Yiyi WANG, Liangpu WANG, Yuyan NI, Zhaoying PAN also contributed to the HP work.

Wiki:

Our wiki was designed by Shiyang WANG, Yaru TIAN and Yufei SHAN. The coding work was finished by Yuanli GAO, Shiyang WANG, with the help of Fankang Meng. The paperwork was finished by the joint effort of Yuanli GAO, Yun Dong, Ziyi ZHAO, Zpeng XU, Yiyi WANG, Liangpu WANG, Yuyan NI, Zhaoying PAN, and finally summarized and modified by Yuanli GAO.

Art work:

Our art work was accomplished by our excellent art designer Yaru TIAN, Yufei SHAN, while Shiyang WANG participated in the discussion.
