Transformation results
None of the plates prepared yesterday grew any cells. We've started a second culture without transformation today, in a plate from the same set, to see if the problem was with our transformation procedure or (hopefully) just with the plates.
Brainstorming continues

- Antibodies are able to both bind antigens and trigger the responses that eliminate them from circulation. All antibodies are glycosylated at conserved positions in their constant regions, and the presence of carbohydrate can be critical for antigen clearance functions such as complement activation. The structure of the attached carbohydrate can also affect antibody activity. Antibody glycosylation can be influenced by the cell in which it is produced, the conformation of the antibody and cell culture conditions. These variables should be considered in the design and production of antibodies with selected specificity and function.

- Construction of a genetic toggle switch in Escherichia coli.

- It has been proposed' that gene-regulatory circuits with virtually any desired property can be constructed from networks of simple regulatory elements. These properties, which include multistability and oscillations, have been found in specialized gene circuits such as the bacteriophage lambda switch and the Cyanobacteria circadian oscillator. However, these behaviours have not been demonstrated in networks of non-specialized regulatory components. Here we present the construction of a genetic toggle switch-a synthetic, bistable gene-regulatory network-in Escherichia coli and provide a simple theory that predicts the conditions necessary for bistability. The toggle is constructed from any two repressible promoters arranged in a mutually inhibitory network. It is flipped between stable states using transient chemical or thermal induction and exhibits a nearly ideal switching threshold. As a practical device, the toggle switch forms a synthetic, addressable cellular memory unit and has implications for biotechnology, biocomputing and gene therapy.
