Veterinary Biochemistry laboratory practical regulations

 Fall semester, academic year 2020/2021

Veterinary Biochemistry laboratory practicals in the fall semester of academic year 2020/2021, considering the pandemic situation, until further regulations or revocation, for the safety of our students and our staff members, will be held as follows:


  1. The relevant chapters of the laboratory manual will be available on Moodle server of the university. Please download them, and as they also function as a report for the laboratory practical, bring a printed, or an editable, fillable electronic version to the lab practical. The textbook is also available for purchase in the bookshop of the campus.
  2. The first introductory part of the labs (overview of the theoretical background of the topic, technical advices, demonstration experiments) will be recorded prior to the practical, and will be uploaded to Moodle as video files. The individual processing of the aforementioned recordings is a compulsory part of the laboratory course. During the in person laboratory practicals only certain manual experiments are to be carried out, the preparation shall be done individually at home.
  3. For each laboratory practical, the relevant chapter of the manual and the instructions given in the video recordings have to be learned thoroughly. The manual has to be filled in beforehand, except those gaps (observations and results) which you have to fill in during practical. Please also read through the relevant notes given during the theoretical lectures.
  4. In order to keep the appropriate physical distancing in the laboratory, the maximum number of participants is limited to 9 persons on each practical. Therefore, the groups will be divided into two subgroups (e.g.: 1/A and 1/B subgroups). The final schedule will be available (downloadable) on the first week of the semester. In accordance, the practical will be held at the time given in the timetable for the first subgroup (i.e.: subgroup 1/A), and 90 minutes later for the second half of the group (i.e.: subgroup 1/B).
  5. You are allowed to take part in your designated group’s practical exclusively, and only because of particular reason you can participate in another group’s practical, with the previous approval from Dr. Csilla Sebők. You can ask for permission via e-mail (, until the working day before the wanted lab till 14:00. In the e-mail please state the name of the demonstrator and the scheduled start of practical chosen.
  6. You have to wear appropriate face covering or face mask, rubber gloves and white lab coat at all times during practical, please bring them with you. All through the duration of the lab, upon entry and the exit you must keep 1.5 m physical distance from one another. You can only take the lab coat, the printed version of the laboratory manual and your pen to the lab bench and must leave everything else in the cupboard of the lab.
  7. At the beginning of each lab you have to answer 5 multiple choice questions in 5 minutes. (Except on the 5th lab at which you have to successfully answer 3 test questions and draw the given molecule’s structure.) The topic of the multiple choice test will cover the currently given chapter of the manual.
  8. After the successful test you will have to carry out certain experiments (you will be informed in forward which ones) with the help of the demonstrator and by the instructions given in the video recording. After completion the given experiment, please fill in the observations and the results in the manual. The face-to-face section of the practical – due to the division of groups – is going to be a maximum of 70 minutes.
  9. After the completion of each experiment you will have to hand in the manual to the demonstrator, and your points will be determined based on the entry test, the quality of your experiments and your observations and results written in the manual (0-5 points). (Due to safety precautions oral tests at the end of the labs will not be held.) You have to achieve the minimum of 2 points for the practical to be successful. The semester will be accepted, if you reached at least 15 points during the 5 practicals.
