AffiASSAY® Alanine Aminotransferase (ALT or SGPT) 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® Alanine Aminotransferase (ALT or SGPT) Activity Colorimetric & Fluorometric Assay Kit
  • Biological samples containing ALT
  • 96-well microplate
  • Microplate reader capable of measuring absorbance or fluorescence
  • Pipettes and tips
  • Microcentrifuge tubes

Protocol:

Sample Preparation:

  • Prepare your biological samples containing ALT. These samples can be cell lysates, tissue homogenates, or purified enzyme preparations.
  • 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 a positive control sample with known ALT activity.

Assay Reaction:

  • Prepare the assay reaction mix by combining the Assay Buffer, ALT Enzyme, and Substrate Mix 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 positive control to the appropriate wells on the microplate.
  • Ensure that the final reaction volume in each well is consistent.

Incubation:

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

Measurement:

  • Using a microplate reader capable of measuring absorbance or fluorescence, measure the absorbance or fluorescence intensity of each well.
  • For colorimetric detection, measure the absorbance at the appropriate wavelength.
  • For fluorometric detection, measure the fluorescence emission at the appropriate excitation and emission wavelengths.

Data Analysis:

  • Calculate the ALT activity in your samples based on their respective absorbance or fluorescence readings.
  • Compare the activity levels to your positive control and perform any necessary normalization.

Results Interpretation:

  • Interpret and analyze your results according to your research objectives.
  • Note any variations or trends in ALT 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® Alanine Aminotransferase (ALT or SGPT) 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.
