Kinetic Dose Response Assay Protocol

HoloMonitor kinetic dose response assay icon

This protocol helps to set up a Kinetic Dose Response Assay using HoloMonitor® M4 and the HoloMonitor® App Suite software. The HoloMonitor® Kinetic Dose Response Assay automatically analyzes drug responses in adherent cells. Results are displayed as an interactive response curve, where results for each condition can be displayed for any selected time point.



  • Interactive dose-response curve
  • Cell count (cells/cm2)
  • Confluence (%)
  • Mean cell volume (μm3)





Seed the cells with about 5 % confluence (ca. 6000 – 11000 cells/cm2).

►Please note that too few cells may lead to inadequate results due to auto-focus failure.

Place the vessel in the incubator and let cells attach for 2-24 hours.

Start the software and wait for complete instrument initialization.

Run an auto-calibration. With successful calibration (as shown in the picture), the instrument is ready to use.

Kinetic dose response assay overview

Sterilize the HoloLids™ according to the HoloLid™ sterilization and use protocol.

Add the treatment to your cells. The final working volumes per well, essential for using HoloLids™, are shown in the table above.

Slide the cell culture vessel onto the Vessel holder, its grips facing towards you. Ensure that the vessel is parallel to the holder. There is a spring that holds the vessel in place.

►When using multi-well plates, place them with the cut-off corner to the left.

Replace the standard lids with the HoloLid™.

Put the vessel holder with the sample on the HoloMonitor® M4 stage.

Select the Kinetic Dose Response Assay and proceed by clicking the Setup Capture button.


Basic setup: Describe the experiment and assign treatments to the wells

Kinetic dose response assay  setup

Enter the experiment name, optional experiment
and cell types.

Select the correct vessel map from the drop-down list.

Start by setting up a new control. Select well/s by marking them with the left mouse button while moving the cursor over the relevant well/s. It is possible to set several controls, e.g. for each cell line if more than one is used in the experiment – by using the Setup New Control button.

4.1 Select control in the Controls and Conditions list. Now, the Setup New Condition button gets activated. Click it to open the Manage Condition window.

4.2. Name the condition/ treatment and choose the drug unit. Select the well/s, type in the corresponding drug dose, and click Add/ Enter. Repeat for as many doses as needed for this drug. The color saturation of the wells is indicative of the dose concentration — the more saturated, the higher the dose. It is possible to add several different conditions, e.g. drugs, to the same control – by using the Setup New Condition button. The name of the condition needs to be unique.

Proceed to Capture setup.

Capture setup: Select the experiment time settings and choose capture positions

Kinetic dose response assay capture

Adjust the default settings for the duration, interval and
the number of positions.

Ensure that the storage requirement for the experiment does not exceed the computer capacity.

► When running an experiment, data needs to be stored on the computer connected to the instrument. Storing data on an external drive (e.g. connected via USB or internet server) may cause data loss due to erratic USB connections or poor internet connection.

Manual focus adjustment
MANUAL FOCUS ADJUSTMENT: The focusing tool is located in the Controls tab. Move the black square or click on the Arrow buttons to move the stage up and down. Save an adjusted focus setting for the selected position by using the Apply Current Focus button. For details, consult the Setup and Operational Manual.

Run a full or quick validation of the selected positions to ensure good image quality.

Click the positions list button to view the position list.

Inspect the images by hovering over the image icon in the list. Move the stage to that position by double-clicking the icon. If the image quality is poor, a warning sign appears. Adjust position location or focus if necessary.

When satisfied with the experiment setup, click Proceed to Capture.

Capture: Review the experiment in real-time during the time-lapse

Click Start Capture.

To stop the experiment ahead of time, click the stop button.

► Note that it is NOT possible to restart the experiment once it has been stopped.

Go to the Experiments tab and open your ongoing experiment to preview the results during the run.

When the Experiment capture finishes, click the Show Result button to get directly to the Results page.

The HoloMonitor® App Suite experiment data can be re-analyzed to generate results for other assay types. Find more information in the overview and the Setup and Operation Manual.
  • The assay results are generated during image capturing.
  • The software automatically analyzes quantitative data generated from each image.
  • For a more detailed analysis all results can be exported.

The results are given as an interactive Dose-Response curve with the time slider, which can be used to view the dose-response over the entire experiment time.

Additionally, cell count (#/cm2), confluence (%), and mean cell volume (µm3) graphs are depicted.

For further analysis, export all results to Excel. The exported data include population data based on means, including data for each captured position and standard deviations.

Image analysis tab

Kinetic dose response assay
It is the users’ responsibility to verify that the software algorithm
was correctly applied during analysis and the results are accurate.
  • An image analysis algorithm filters out images of poor quality and excludes them from results data.
  • Include or exclude images from results analysis. See the Image quality guide for more information.

The captured images from the experiment are displayed in a tree-view list. Clicking an item in the tree will show a list of all images contained in the selected level/category.

Checked checkboxes — all images are included.
Empty checkboxes — all images are excluded.
Checkboxes with a dash — some images are included.
Symbols in the list show cell analysis (yellow exclamation mark) or image quality warning (red exclamation mark).

It is possible to adjust the Sensitivity of image(s) and view the image threshold and markers.
