Human Thyroxine - T3 Elisa Kit, 96 Tests In 96 Well Plate

The Human Free Thyroxine (FT4) ELISA Kit is a sensitive and specific assay designed for the quantitative detection of free thyroxine (FT4) levels in human serum, plasma, culture media, and other biological fluids. This kit is ideal for research into thyroid function, hormonal balance, and endocrine disorders.

Purpose

• Quantification of FT4 Levels:
  • Detect and measure free thyroxine concentrations in human biological samples for research into thyroid hormone regulation and metabolic processes.
• Sample Compatibility:
  • Suitable for serum, plasma, culture media, and other biological fluids.

Principle

The assay employs a Sandwich-ELISA technique to ensure accurate and reliable quantification of FT4. The process includes:

1. Pre-Coated Plate:
   • Microelisa stripplate wells are pre-coated with an antibody specific to FT4.
2. Sample and Standard Addition:
   • Standards and samples are added to the wells, where FT4 in the sample binds to the immobilized antibody.
3. HRP-Conjugated Detection:
   • A Horseradish Peroxidase (HRP)-conjugated antibody specific to FT4 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 FT4.
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:
   • FT4 concentrations are calculated by comparing OD values to a standard curve.

Key Features

1. High Sensitivity and Specificity:
   • Detects low levels of FT4 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 FT4 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.
