New page

==Obtaining and preparing the lab journal==
*Everybody who is performing any experimental work has to own and use a lab journal.
*The lab journal can be picked up at the DCN secretariat.
*The cover of the lab journal has to provide the following information:
A)The name of the experimenter (names if lab journal is continued by a successor, see below)
B)The title of the study/project
C)The starting date and eventually the date of finalization of the journal.

==Record keeping: general instructions==
*All pages are numbered before using the lab journal.
*The first 4 pages will be assigned to create a table of content of the main experiments (with page numbers)
*The standard language of the lab journal is English.
*The header of the description of every new experiment shows a title and the date.
*The respective experimental protocol has to be clearly depicted. If you used paper forms then the form has to be transferred or copied and pasted into the lab journal.
*Every single step of the experiment has to be described in a way that an external reader can fully reproduce the experiment.
*If applicable one can refer to the protocols and descriptions of previous experiments in the same lab journal WITH the respective page numbers.
*When referring to previous descriptions or protocols EVERY single modification or exception has to be noted.
*When using solutions with lot-numbers (e.g. enzymes, antibodies, specific chemicals etc.) the lot numbers has to be noted in the lab journal.
*Clearly note how samples are marked and where they are stored.
*All incidences, perceptions, results and conclusions have to be written down in a clear, transparent and reproducible way.
*Also experiments that failed or have been aborted need to be noted down, including a clear explanation of what caused the failure of abortion.
*It is strictly forbidden to remove pages or to take the lab journal home.

==Data==
*Write down the name and location of all data files that are connected to a given experiment.

==Control system==
*Every month the direct supervisor will check the lab journal.
*The direct supervisor will place her/his signature underneath the last page that was checked. If needed, shortcomings will be directly discussed with the experimenter.
*Every 3 months, some lab journals will be checked for compliance with these rules by the technical staff.

==Storing the lab journal==
*Finalized lab journals that are not directly relevant for ongoing studies anymore will be delivered to the DCN secretary and centrally archived.
*At regular intervals but at latest after a experimenter finalized a lab journal, the journal needs to be scanned and electronically stored. One file per lab journal!
*Lab journals which are not filled after a experimenter has finalized the study can be continued by experimenters working on continuation of the project or a similar study.
