Does ELISA require technical replication? How to set the positive or negative control?

Source: Elabscience®Published: Mar 05,2024

It is recommended that customers do technical repetition, on the one hand can confirm the operation method, on the other hand can verify and improve the accuracy of the experimental results. A positive control in an ELISA test can be considered the standard product. Negative control is a blank matrix or a matrix solution with known low concentration that has homology and homogeneity with the object to be picked up, which is generally difficult to obtain, and can be set as a negative control if available. The routine is to set a blank control, that is, a sample diluent.
