last Thursday we performed the first set of DNA transformations with a small circle of friends, Ferenc Szalai, Attila Nemes and András Márton Juhász. this was a basic test of the lab to prove if multiple people can work in it together.
Yesterday I performed the first successful DNA transformation in the new lab, set up at FabLab Budapest. The transformation was simply the pGLO gene earlier isolated at the University of Szeged, into e.coli HB 101. The green spots on the image above are the bacteria with the Green Fluorescent Protein in then.
This gives reassurance that the crude tools here in the lab can do real work
Tomorrow, I’ll hold a presentation on bio.display at the Iwasaki Lab of the Center for Advanced Biomedical Sciences at Waseda University in Tokyo, at 2:30pm local time. See Iwasaki Sensei’s page on what he’s mostly up to.
Today the Hungarian newspaper HVG mentions bio.display in a feature about 3D printers in general, and its use in edible printing & medical applications.
Using the same method to create the flashing signs, the researchers engineered a simple bacterial sensor capable of detecting low levels of arsenic. In this biological sensor, decreases in the frequency of the oscillations of the cells’ blinking pattern indicate the presence and amount of the arsenic poison.
