Some might find it tough to get started on writing laboratory reports when first entering university (or high school), especially if you do not have a background in biology, as was the case with me. To give you an idea of what student experiment reports look like, I upload some examples here. They often include theoretical background of the experiment so that you can better understand what kind of phenomenon you are investigating. I deliberately did not alter or correct the original reports written during undergraduate course in order to show you what level is expected of you at university. All reports scored 80% and above, so feel free to use them for reference (with a grain of salt). However, as you are aware, your professors can and probably will run your work through plagiarism check software, so to protect yourself from failing a year or getting expelled (if you are a university student), do not copy-paste, make sure to use your own words, and remember to include references.
Three reports describing basic experiments using microorganisms: isolation and screening of microorganisms from a soil sample, measuring the multiplication rate of E. coli, and induction of β-galactosidase with measuring its activity. Those reports gained full points during assessment, so you can consider them relatively reliable.
Irradiating E. coli with UV light in order to induce mutations that will result in antibiotic resistance.
Determination of the enzyme activity of cellulase in T. reesei filamentous fungi cultivated in the presence of cellulose and glucose.
Incorporating plasmid DNA containing an antibiotic resistance gene into competent E. coli cells.
Transformation experiment extended. Includes transformation of E. coli. (introduction of plasmid DNA) followed by isolation of plasmid DNA from the E. coli cells using the alkaline SDS method, cleaving double-stranded plasmid DNA with restriction enzymes, and separating the resultant DNA fragments by agarose gel electrophoresis.
Separation of of proteins from rat liver by SDS-polyacrylamide gel electrophoresis (SDS-PAGE), followed by detection of a specific protein (GAPDH) by Western Blotting using membrane transfer and rections with primary and secondary antibodies.
