University biochemistry experiment report template exampleThe following is an example of a university biochemistry experiment report template:
* * I. Title **
[Experiment Name] Experiment Report
* * 2. Name, student number, experiment time, experiment group and group members **
1. [Name: Your name]
2. Student ID: [specific student ID]
3. Experiment time: [YY
4. [Experimental Group: Group X]
5. [Group Members: [List member names]
* * 3. Purpose of the experiment **
Explain the purpose of this biochemical experiment, such as mastering the determination method of a certain substance, understanding the principle of a biochemical reaction, etc.
* * 4. Experiment Principle **
Explain in detail the biochemical principles that the experiment is based on, including the chemical reactions involved and the interactions between biological molecules. For example, the Coomassie Brilliant Blue Method was used to determine the protein content. The principle was that the Coomassie Brilliant Blue Method was used to determine the protein concentration. Based on the principle of protein dye binding, Coomassie Brilliant Blue G-250 dye was brownish-red in acidic solution. After binding with the protein through van der Waals bond, it turned blue. When it combined with the protein in acidic solution, the position of the maximum absorption peak (lmax) of the dye changed from 465 mm to 595 mm, and within a certain concentration range of the protein, it complied with Beer's Law. By measuring the increase in light absorption at 595mn, the amount of protein bound to the dye could be known, and the dye mainly bound to the basic and aromatic acid residue in the protein.
* * 5. Experimental Materials and Instruments **
1. * * Experiment Materials **
- List the biological samples (such as tissues, cells, blood, etc.) and reagents used in the experiment (including the name, purity, concentration, and other relevant information).
2. * * Experimental instrument **
- Write down the instruments and equipment used in the experiment (such as a centrifugal machine, a thermometer, a pipet, etc.) and their models.
* * 6. Experimental Steps **
1. Explain the operation process of the experiment in detail, including the preparation work before the experiment (such as sample pre-treatment, instrument warm-up, etc.).
2. According to the order of the experiment, the main operation steps were described step by step. For example, the experiment of determining the content of protein by Coomassie Brilliant Blue Method, including the preparation of the standard curve (preparing different concentration of protein standard solution, adding Coomassie Brilliant Blue reagent, measuring the light absorption, etc.) and the determination steps of unknown samples.
3. He mentioned the precautions during the experiment, such as the order of addition of certain reagents, the temperature and time control of the reaction, and so on.
* * 7. Experiment result **
1. * * Data Record **
- The experimental data was presented in the form of a table or chart (such as a bar chart, a line chart, etc.), including various values measured in the experiment (such as the absorption, concentration, etc.).
2. * * Analysis of the results **
- To analyze the experimental results, such as calculating the content of the target substance in the unknown sample according to the standard curve, and to analyze whether the experimental results meet the expectations. If they do not meet the expectations, discuss the possible reasons (such as experimental operation errors, instrument failures, differences in the sample itself, etc.).
* * 8. Experiment Discussion **
1. The results of the experiment were discussed in depth, and the experimental results were linked to the existing biochemical knowledge to explain the experimental phenomenon.
2. The advantages and disadvantages of the experiment were discussed, such as the sensitivity and accuracy of the experimental method, and the simplicity of the operation.
3. Make suggestions to improve the experiment, such as the optimization of experimental steps, experimental materials, or equipment.
* * 9. Experiment conclusion **
He summarized the main findings of the experiment and answered whether the purpose of the experiment was achieved. He then came to a clear conclusion.
