Frequently asked questions
What is a Single Radial Diffusion (SRD) assay?
SRD is a quantitative immunodiffusion assay in which antigen diffuses from a well into agarose containing a specific antibody. When antigen and antibody reach equivalence, a precipitin ring forms. The ring size is used to determine antigen concentration relative to standards.
Why is SRD still used?
SRD remains widely respected because it is simple in principle, uses a direct immunological readout, and has a long history in established analytical workflows. It is especially valued where standardized antigen quantification is required.
Why run SRD on Macrolab?
Macrolab helps laboratories move SRD from a largely manual setup toward a more standardized and repeatable operational workflow. The value is not changing the assay principle, but improving consistency, execution, and long-term usability.
Is SRD qualitative or quantitative?
SRD is quantitative. The precipitin ring diameter or area is compared with known standards to calculate antigen concentration.
Which factors influence SRD performance?
Key factors include antibody concentration in the gel, antigen concentration, well geometry, incubation conditions, gel quality, reagent integrity, and the accuracy of ring measurement.
