Radioimmunoassay Technology

Radioimmunoassay combines radionuclide tracer sensitivity with antigen-antibody specificity. The portfolio includes classic competitive RIA methods and non-competitive IRMA methods for quantitative and qualitative laboratory testing.

Radioimmunoassay (RIA)

A competitive binding method using a radiolabeled antigen. Results are calculated from the relationship between bound radioactivity and analyte concentration.

Immunoradiometric Assay (IRMA)

A non-competitive method using a radiolabeled antibody. The measured signal is positively correlated with analyte concentration and can provide high analytical sensitivity.

Typical Kit Components

Kit configuration varies by assay, but may include the following components.

1

Calibrators

Reference materials used to establish assay calibration curves.

2

Quality Controls

Control materials used to monitor assay performance.

3

Labeled Reagent

I-125-labeled antigen or antibody according to the assay format.

4

Antibody / Coated Tubes

Specific binding reagents and solid-phase components where applicable.

Supporting equipment for radioimmunoassay laboratory workflows

Supporting Laboratory Equipment

  • Constant-temperature water bath or incubator
  • Temperature-controlled shaker/incubator
  • Refrigerated reagent and sample storage
  • Laboratory centrifuge for bound/free separation
  • Gamma counter / radioimmunoassay analyzer
  • Pipettes, tips, tube racks and compatible reaction tubes
  • Approved radioactive-waste handling and storage supplies

Typical Laboratory Workflow

Assay procedures depend on the specific kit instructions for use. A typical workflow includes preparation of calibrators and specimens, controlled incubation, bound/free separation, gamma counting and calculation from the calibration curve.

Important: Radioimmunoassay products contain or use radioactive I-125 materials. Purchase, transport, storage, use and disposal must be handled only by appropriately licensed institutions and trained personnel in accordance with applicable local regulations.
