Today, LiHong was a little busy with her work and so, we shadowed her friend Fujing for the day. Fujing is a new PhD student and she has been working with proteins too. She brought us into the lab and showed how she was going to (hopefully) bind alpha and gamma proteins together. After she mixed both type of proteins together, she continued to carry out dialysis like what Dawei did.
Interestingly, Paul (another researcher) came in and talked to us. He introduced two-dimensional gel electrophoresis which, is a step to separate proteins according to their isoelectric point and molecular mass. In the medical field, he said, 2D gel electrophoresis can be applied to identify unusual proteins in a brain like the analysis of brain proteins in brain cancer compared to normal brain cells. Soon after we were left wandering in the lab, observing others.
To end off:
Research is a repetitive process and it demands patience. It could take up days to weeks or even months to obtain a desirable result. Nevertheless, the rewards are fruitful as the gain in more knowledge is truly enlightening.
