Immunoassays
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Immunoassays are laboratory techniques used to detect and quantify specific proteins, hormones, or other molecules within a sample by leveraging the specificity of antibody-antigen interactions. They are widely employed in medical diagnostics, research, and biochemistry to identify the presence or concentration of target analytes with high sensitivity and specificity.
Key Features
- Utilizes antibody-antigen binding for detection
- High sensitivity and specificity
- Versatile applications including clinical diagnostics, research, and drug testing
- Various formats such as ELISA, Radioimmunoassay (RIA), Fluorescence Immunoassay, and Lateral Flow Assays
- Capable of multiplexing to detect multiple analytes simultaneously
- Relatively rapid and cost-effective compared to other analytical methods
Pros
- Highly sensitive and specific for target molecules
- Widely validated and standardized methods
- Applicable to a broad range of biological samples
- Useful for early diagnosis of diseases
- Cost-effective for large-scale screening
Cons
- Requires high-quality antibodies for accurate results
- Potential for cross-reactivity leading to false positives or negatives
- Limited dynamic range in some formats
- Sometimes complex sample preparation procedures
- Not always suitable for real-time analysis
