Another version of the text uses the word "adipisici" (rather than "adipisici'''ng'''"; the digraph ''ng'' at the end of words is alien to classical Latin). Other versions of lorem ipsum include additional words to add variety so that repeated verses will not word-wrap on the same phrases.

About Us

Our team consists of twelve students from Linköping University who are interested in biotechnology. All of us have been studying engineering in technincal or chemical biology for at least three years. In our group we also have two seniors, a professor who is head of the division of information coding and a med. doctor in biomedicine. Our goal with the project is to reach the finals in the iGEM competition and to be able to take our team and project to Boston.

Our idea

Our Project idea is to first grow E.Coli that has been genetically modified to produce an antibody with the enzyme luciferase attached to its constant part. At first the antibody will be constructed to adhere to a peanut antigen, but our long time goal is to be able to switch to whichever antigen desired. Luciferase is an enzyme that cleaves luciferin in the presence of ATP, giving rise to a long lasting green light by the principle of luminescence. Luminescence is superior to fluorescence due to, e.g. lack of fading.

To distinguish between the antibodies that has adhered to the antigen and the ones that has not, we use RFP attached to a fake, but identical, antigen. The extra antibodies adhere to the fake antigen and their light gets canceled out. The cancellation is due to the properties of RFP, which acts as a quencher on the light emitted from the luciferase/luciferin complex. The fake antigen with RFP attached will also be grown inside a genetically modified E.Coli.

By first adding the antibodies to a solution with known concentrations of peanut antigen and then adding the fake antigen complex, to cancel out the unbounded antibodies, the intensity of light emitted should be proportional to the concentration of antigen in the solution. This way we can determine how much antigen are present, and if there are any at all.
