First, you’ll need to remove the ignition coil and spark plug from one of the engine’s cylinders.
Then, you’ll insert the compression gauge into the spark plug hole and crank the engine several times. The compression gauge will give you a reading, which you should record. Repeat this process for all cylinders in the engine.
Ideally, all cylinders should have similar compression readings with a variance of no more than 10%. If there is a significant difference in compression between cylinders, it may indicate an issue with the engine, such as worn piston rings or a blown head gasket. By cranking the engine and recording the readings accurately, you’ll be able to diagnose any issues with the engine before they become major problems.
Interpreting Results and Troubleshooting
Performing an enzyme-linked immunosorbent assay (ELISA) test can provide valuable information about the presence or absence of a specific antigen. To begin the process, a sample is added to a well containing the antigen-specific antibody. If the antigen is present in the sample, it will bind to the antibody, and any unbound material is washed away.
A secondary antibody, which is linked to an enzyme, is then added, which will bind to the bound antigen-specific antibody. Any excess secondary antibody is washed away, and a substrate solution is added, which will undergo a color change in the presence of the enzyme. By measuring the absorbance of the solution in each well, we can determine whether or not the antigen is present in the sample.
If the results are not as expected, it might be necessary to troubleshoot the process by double-checking reagent concentrations or ensuring the correct incubation times were followed. Using ELISA, researchers can gain critical insights about the presence and levels of specific antigens, helping to diagnose diseases and monitor treatment effectiveness.
