Human beta2-microglobulin, BMG ELISA Kit

The Human β2-Microglobulin (β2-MG) ELISA Kit is a highly sensitive and specific assay designed for the quantitative detection of β2-MG levels in human serum, plasma, culture media, and other biological fluids. This kit is essential for research into renal function, immune response, and related disorders.

Purpose

• Quantification of β2-MG Levels:
  • Detect and measure β2-MG concentrations in human biological samples to study renal function, immune regulation, and disease biomarkers.
• Sample Compatibility:
  • Suitable for serum, plasma, culture media, and other biological fluids.

Principle

The assay employs a Sandwich-ELISA technique for the accurate and reliable quantification of β2-MG. The process includes:

1. Pre-Coated Plate:
   • Microelisa stripplate wells are pre-coated with an antibody specific to β2-MG.
2. Sample and Standard Addition:
   • Standards and samples are added to the wells, where β2-MG in the sample binds to the immobilized antibody.
3. HRP-Conjugated Detection:
   • A Horseradish Peroxidase (HRP)-conjugated antibody specific to β2-MG is added, forming a sandwich complex.
4. Washing Step:
   • Free and unbound components are washed away to minimize background interference.
5. Substrate Reaction:
   • TMB substrate solution reacts with HRP, producing a blue color in wells containing β2-MG.
6. Stop Reaction and Measurement:
   • A stop solution is added, changing the color from blue to yellow. Optical density (OD) is measured at 450 nm using a spectrophotometer.
7. Quantification:
   • β2-MG concentrations are calculated by comparing OD values to a standard curve.

Key Features

1. High Sensitivity and Specificity:
   • Detects low levels of β2-MG with minimal cross-reactivity or interference.
2. Wide Sample Compatibility:
   • Validated for serum, plasma, culture media, and other biological fluids.
3. Quantitative Results:
   • Provides precise measurement of β2-MG concentrations using a standard curve.
4. Ease of Use:
   • Includes pre-coated plates and ready-to-use reagents for streamlined workflow.
5. Reproducibility:
   • Ensures consistent and reliable results across multiple experiments.
