What does IRMA mean in UNCLASSIFIED
IRMA (Immuno Radio Metric Assay) is a highly sensitive and specific immunological technique used to measure the concentration of antigens or antibodies in biological samples. It employs the principles of radioimmunoassay (RIA), utilizing radioactive isotopes to quantify the amount of the target molecule.
IRMA meaning in Unclassified in Miscellaneous
IRMA mostly used in an acronym Unclassified in Category Miscellaneous that means Immuno Radio Metric Assay
Shorthand: IRMA,
Full Form: Immuno Radio Metric Assay
For more information of "Immuno Radio Metric Assay", see the section below.
Principle of IRMA
IRMA involves the following steps:
- Antigen or Antibody Immobilization: The antigen or antibody to be measured is immobilized on a solid support, such as a microtiter plate or magnetic beads.
- Radiolabeled Antigen or Antibody: A radiolabeled antigen or antibody, known as the tracer, is added to the system. The tracer competes with the unlabeled antigen or antibody for binding to the immobilized target molecules.
- Separation: The bound and unbound tracers are separated using a wash step, removing the unbound tracer from the system.
- Quantification: The amount of bound tracer is measured using a scintillation counter, which detects the radioactivity emitted by the bound tracer. The radioactivity is directly proportional to the concentration of the target molecule in the sample.
Advantages of IRMA
- High Sensitivity: IRMA offers extremely high sensitivity, allowing for the detection of very low concentrations of antigens or antibodies.
- Specificity: The use of specific antibodies or antigens ensures high specificity, minimizing cross-reactivity with other molecules.
- Quantitation: IRMA provides accurate and precise quantitation of the target molecule, allowing for the comparison of samples and the determination of concentrations.
- Wide Applications: IRMA has numerous applications in research and clinical settings, including the diagnosis and monitoring of diseases, drug discovery, and environmental monitoring.
Essential Questions and Answers on Immuno Radio Metric Assay in "MISCELLANEOUS»UNFILED"
What is IRMA?
IRMA stands for Immuno Radio Metric Assay. It is a laboratory technique used to measure the concentration of an antigen or antibody in a sample. It uses radioactive isotopes to label the antigen or antibody, and the amount of radioactivity is measured to determine the concentration of the target molecule.
How does IRMA work?
IRMA involves several steps:
- The antigen or antibody of interest is labeled with a radioactive isotope.
- The labeled antigen or antibody is incubated with the sample containing the target molecule.
- The labeled antigen or antibody binds to the target molecule, forming an antigen-antibody complex.
- The unbound labeled antigen or antibody is removed.
- The amount of radioactivity associated with the antigen-antibody complex is measured, which is proportional to the concentration of the target molecule in the sample.
What are the advantages of IRMA?
IRMA offers several advantages:
- High sensitivity and specificity
- Precise and accurate measurements
- Can quantify very low concentrations of target molecules
- Has a wide range of applications in various fields, such as medical diagnostics, environmental monitoring, and food analysis.
What are the limitations of IRMA?
IRMA has some limitations:
- Requires the use of radioactive isotopes, which can pose safety concerns and disposal issues.
