Human Super Oxidase Dimutase (SOD) ELISA Kit (Enzyme Activity)

The Human Super Oxidase Dismutase (SOD) ELISA Kit (Enzyme Activity) is a precise and reliable tool designed to measure SOD enzyme activity in various biological fluids, including human serum, plasma, culture media, and other sample types. By employing a robust Sandwich-ELISA technique, this kit delivers accurate results, enabling researchers to assess the functional activity of SOD in studies related to oxidative stress, enzymatic defense mechanisms, and related physiological processes.

Purpose:

This ELISA kit is specifically designed to:

• Quantify SOD enzyme activity in human biological samples.
• Support research in oxidative stress, antioxidant defense systems, and related metabolic pathways.
• Facilitate the analysis of SOD functionality in various experimental and clinical research settings.

Principle of the Assay:

The assay uses a Sandwich-ELISA approach to detect SOD enzyme activity:

1. Pre-Coated Microplate:
   • Each well is pre-coated with a capture antibody specific for SOD, ensuring selective binding of the enzyme.
2. Sample and Standards Addition:
   • Standards or biological samples containing SOD are added to the wells, where SOD binds to the capture antibody.
3. HRP-Conjugated Antibody Binding:
   • A Horseradish Peroxidase (HRP)-conjugated antibody specific for SOD binds to a distinct epitope on the enzyme, forming a "sandwich" complex.
4. Signal Development:
   • TMB substrate reacts with the HRP to produce a colorimetric signal that is directly proportional to the SOD enzyme activity in the sample.
5. Measurement:
   • Optical density (OD) is measured spectrophotometrically at 450 nm, and enzyme activity is calculated by comparing the OD values to a standard curve.

Kit Components:

• Pre-Coated Microelisa Stripplate: Pre-coated with anti-SOD capture antibody.
• SOD Standards: For generating a standard curve to determine enzyme activity.
• HRP-Conjugated Antibody: For specific detection of SOD.
• Sample and Standard Diluent: Ensures proper sample preparation.
• Wash Buffer: Removes unbound components during washing steps.
• TMB Substrate Solution: Reacts with HRP to develop a colorimetric signal.
• Stop Solution: Stops the enzymatic reaction for stable measurements.
• Instruction Manual: Detailed protocol for assay execution.
