AffiASSAY® GAPDH Colorimetric Activity Assay Kit
The AffiASSAY® GAPDH Colorimetric Activity Assay Kit provides a reliable method for the quantification of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) activity in various biological samples. This assay kit offers a colorimetric detection method, enabling researchers to study glycolysis, cellular metabolism, and GAPDH-associated pathways with precision and convenience.
Key Features:
- High Sensitivity: The assay kit can detect low levels of GAPDH activity, ensuring accurate quantification in biological samples.
- Wide Application: The AffiASSAY® GAPDH Colorimetric Activity Assay Kit is compatible with various sample types, including cell lysates, tissues, and purified enzyme preparations.
- Quick and Easy: With a streamlined protocol, you can obtain results rapidly, saving time and resources in the laboratory.
- Cost-Effective: Our kit provides an affordable solution for measuring GAPDH activity, reducing experimental costs without compromising data quality.
Assay Principle:
The assay kit measures GAPDH activity based on the enzymatic conversion of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (1,3-BPG), coupled with the reduction of NAD+ to NADH. The increase in absorbance at 450 nm is directly proportional to the GAPDH activity in the sample.
Applications:
- Glycolysis Studies: Investigate the role of GAPDH in the glycolytic pathway and energy metabolism.
- Cellular Metabolism Research: Study the regulation of GAPDH activity in response to metabolic changes and cellular signaling pathways.
- Drug Discovery: Screen for compounds that modulate GAPDH activity as potential therapeutics for metabolic disorders and cancer.
Kit Contents:

Protocol:
Assay Plate Setup:
- Label the microplate wells according to your experimental design, including wells for your samples, standards, and controls.
- If using controls, prepare control samples without GAPDH to serve as background controls.
Sample and Standard Addition:
- Add 50-100 µL of your prepared samples and standard solutions to the appropriate wells on the microplate.
- Ensure that the final reaction volume in each well is consistent.
Assay Reaction:
- Prepare the GAPDH Assay Buffer by diluting as instructed in the kit manual.
- Add the GAPDH Substrate Mix and GAPDH Enzyme Mix to each well to initiate the reaction.
- Incubate the microplate at the appropriate temperature (as specified in the kit instructions) for a recommended time to allow the enzymatic reaction to proceed.
Colorimetric Measurement:
- After the incubation period, measure the absorbance at 450 nm using a microplate reader.
Data Analysis:
- Calculate the GAPDH activity in your samples based on the absorbance readings and standard curve generated from the standard solutions.
Results Interpretation:
- Interpret and analyze your results according to your research objectives.
- Observe any variations or trends in GAPDH activity among your samples.
Data Presentation:
- Prepare your data for presentation or publication, and include the appropriate statistical analysis if required.
Cleanup:
- Dispose of all waste materials, including used assay components, according to your laboratory's safety protocols.
- Always refer to the specific instructions provided with the AffiASSAY® GAPDH Colorimetric Activity Assay Kit for any kit-specific details or variations in the protocol.
- Additionally, ensure that you adhere to the best practices and safety guidelines in your laboratory while conducting the assay.
