AffiASSAY® Asparaginase Activity Colorimetric & Fluorometric Assay Kit

AffiASSAY® Asparaginase Activity Colorimetric & Fluorometric Assay Kit is designed to provide precise and reliable measurements of asparaginase enzyme activity in biological samples. This assay kit offers both colorimetric and fluorometric detection methods, providing flexibility for researchers in biochemistry, enzymology, and cancer research.

Key Features:

  • High Sensitivity: Our assay kit is optimized to detect even low levels of asparaginase activity, allowing for accurate quantification in a wide range of samples.
  • Colorimetric and Fluorometric Detection: Choose between colorimetric or fluorometric detection methods based on your experimental needs, ensuring robust and reproducible results.
  • Wide Application: The AffiASSAY® Asparaginase Activity Colorimetric & Fluorometric Assay Kit can be used with various sample types, including cell lysates, tissue homogenates, serum, plasma, and culture supernatants.
  • Quick and Easy: With a simple and streamlined protocol, you can obtain results in just a few easy steps, saving you valuable time in the lab.
  • Versatile: Whether you're studying cancer metabolism, evaluating asparaginase therapy efficacy, or screening potential inhibitors or activators of asparaginase, our kit provides the versatility you need.

Assay Principle:

This assay kit employs both colorimetric and fluorometric methods based on the enzymatic conversion of asparagine into aspartic acid and ammonia by asparaginase. The release of ammonia can be detected either by a colorimetric reaction or by measuring the fluorescence of a fluorogenic probe, allowing for precise quantification of asparaginase activity.


  • Cancer Metabolism: Study the role of asparaginase in cancer metabolism, particularly in the context of asparagine dependency in certain types of cancer cells.
  • Therapeutic Monitoring: Assess asparaginase activity in patient samples to monitor the efficacy of asparaginase therapy in leukemia and other malignancies.
  • Drug Discovery: Screen potential asparaginase inhibitors or activators for their pharmacological effects, aiding in drug development for cancer treatment.

Kit Contents:

  • Assay Buffer
  • Asparagine Substrate
  • Asparaginase Enzyme

AffiASSAY® Asparaginase Activity Colorimetric & Fluorometric Assay Kit Protocol:

[Please note that this protocol is a general guideline, and you should always refer to the specific instructions provided in the kit manual for accurate and detailed information.]

Materials Needed:

  • AffiASSAY® Asparaginase Activity Colorimetric & Fluorometric Assay Kit
  • Biological samples containing asparaginase
  • 96-well microplate
  • Microplate reader capable of measuring absorbance at specific wavelengths (for colorimetric detection) and fluorescence intensity (for fluorometric detection)
  • Pipettes and tips
  • Microcentrifuge tubes


Sample Preparation:

  • Prepare your biological samples containing asparaginase. These samples can be cell lysates, tissue homogenates, serum, plasma, or culture supernatants.
  • Ensure that your samples are stored and handled according to your specific experimental requirements.

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 with known asparaginase activity.

Assay Reaction:

  • Prepare the assay reaction mix by combining the Assay Buffer, Asparagine Substrate, and Asparaginase Enzyme from the kit as instructed.
  • Add 50-100 µL of the assay reaction mix to each well of the microplate.

Sample and Control Addition:

  • Add 50-100 µL of your prepared samples and control samples to the appropriate wells on the microplate.
  • Ensure that the final reaction volume in each well is consistent.


  • Incubate the microplate at the appropriate temperature (as specified in the kit instructions) for a recommended time to allow the enzymatic reaction to occur.


  • For Colorimetric Detection: Measure the absorbance of each well at a specific wavelength (provided by the kit) using a microplate reader.
  • For Fluorometric Detection: Measure the fluorescence intensity of each well using a fluorescence microplate reader with appropriate excitation and emission wavelengths (provided by the kit).

Data Analysis:

  • Calculate the asparaginase activity in your samples based on their respective absorbance readings (for colorimetric detection) or fluorescence intensity readings (for fluorometric detection) and compare them to the standard curve.

Results Interpretation:

  • Interpret and analyze your results according to your research objectives.
  • Note any variations or trends in asparaginase activity among your samples.

Data Presentation:

  • Prepare your data for presentation or publication, and include the appropriate statistical analysis if required.


  • 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® Asparaginase Activity Colorimetric & Fluorometric 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.
