Question
When running a gel, you need to have a positive control and a negative control. What do these mean and what are they each used for?
Answers
GPT 3.5
A positive control is a sample that is known to produce the expected result in a gel. It is used to ensure that the experimental conditions are working properly and that the gel is functioning correctly. A positive control helps to confirm that the experimental procedure is able to detect the target molecule or substance.
A negative control is a sample that should not produce a signal or result in the gel. It is used to ensure that any detected results are not due to contamination or non-specific interactions. A negative control helps to confirm that any observed results are specifically due to the presence or absence of the target molecule or substance being studied.
Overall, positive and negative controls are essential for validating the experimental results and ensuring the accuracy and reliability of the gel electrophoresis experiment.
