Different types of controls

positive and negative

In order to unambiguously verify a test result, a positive control and a negative control are required. A solution containing the antibody or antigen under investigation, usually in a defined quantity, is used as a positive control. Negative controls are solutions without antibody or antigen

How to use controls

For optimal comparison, controls must be diluted in the same way as the sample. It is important that controls are pipetted with the same method on the same gel or plate as the samples to create the same conditions. Inlab controls are recommended for constant observation of test performance in your own laboratory.

Why using controls?

Controls are used firstly to normalize or standardize any molecular biology method and secondly to validate the assay and calculate the test results.
