Complementation Tests

Complementation Tests

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

To highlight the need for streamlined testing of complement deficiencies, activation, and inhibition.

Main Methods:

Review of existing literature on complement analysis techniques.
Evaluation of various multiplex assay platforms for complement component measurement.
Analysis of current research and diagnostic applications of multiplex complement testing.

Main Results:

Multiplex testing presents a viable strategy to overcome limitations of single-analyte assays.
Several multiplex methods show promise for simultaneous quantification of complement components.
Research and diagnostic use of multiplex complement analysis is emerging despite inherent complexities.

Conclusions:

Multiplex analysis holds significant potential for improving the comprehensive assessment of the complement system.
