Cell passaging or splitting is a technique that enables an individual to keep cells alive and growing under cultured conditions for extended periods of time. Cells should be passed when they are 90%-100% confluent. You have to do the cell passage on every second to fourth day (i.e. on every Monday, Wednesday and Friday).

After reaching the confluency, the cells do not get enough nutrients and do not have enough place where they can extend. The colour of the medium switches from reddish-pink to orange or yellow which shows acidic metabolic products.

Eukaryotic cells, derived from multicellular animal eukaryotes, can be maintained in culturing medias. Aside from temperature and gas mixture, the most commonly varied factor in eucaryotic culture systems is the growth medium.

The following protocol is used to succesfully introduce foreign plasmid DNA into pluripotent cells through a chemical way, PEI mediated transfection. PEI stands for Poliethilenimine, a cationic polymer which can bind nucleic acids and helps the DNA to get into the cells by receptor-mediated endocytosis.

Ligand treatment is a procedure when we add the appropriate ligand to the nuclear receptor (NR, transcription factor). The NR got into the cells through a previous transfection step. After treatment the ligand-binded NRs will dimerize and bind to the DNA at specific Nuclear receptor Response Elements and this will promote the gene expression of the downstream gene. In further examinations we detect the expression level of the target gene by Luciferase assay. [https://2010.igem.org/Team:Debrecen-Hungary/protocols/Ligand_Treatment Read more...]

Welcome To Our Protocols

"Science is nothing else but the art of proper reproducibility. "


The iGEM experience is not merely a project or a conference, but it was the way that most of our students got acquainted with the world of biological research laboratory. Pipettes, solutions, gels, electrodes, dishes and other scary machinery quickly filled our lives. From day one we saw the vast importance of teaching our students to keep a proper laboratory journal. As time passed and our project grew., and with growth sprouted the idea of keeping an electronic laboratory journal with texts and video’s depicting the proper way of doing our niche of science. And so, we present to you our combined effort a text and video version

Restriction enzyme digestion

BioBrick standard biological parts are flanked by well characterized upstream and downstream sequences which are technically not considered part of the BioBrick part (aka prefix and suffix). These up/down stream segments contain restriction sites for specific restriction enzymes, which allows for the simple creation of larger BioBrick parts by chaining together smaller ones in any desired order.
