Alanine Transaminase Activity Assay

April 1, 2019

EP143 v1.0


Key Steps:

Other Required Materials:

Measurement of alanine transaminase (ALT) activity from Emulate Liver-Chip effluent samples

  • Prepare all reagents, samples, and standards
  • Run the assay
  • Read the plate
  • Alanine Transaminase Activity Assay Kit (Colorimetric / Fluorometric) (Abcam Cat No. ab105134)
  • Plate reader


Sample type

Liver-Chip effluent

See Protocol EP124 Emulate Effluent Sampling.

Liver-Chip assay flow rate


30 µL / h

Liver-Chip effluent dilution



Note: Sample dilution may need to be adjusted further to accommodate for any experimental modifications by the user. ALT levels will change depending on cell injury status or based on donor-to-donor variability. Therefore, sample dilutions may need to be modified to accommodate different experimental conditions or cells from different donors.

Run assay as described on supplier site

Liver-Chip data range

150–3000 mU / mL
