Microfluidics application note
Published on 27 August 2019
This application note presents how to perform cell culture on chip using the Cell and Biology Pack and the MicroSlides developed by ALine Inc.
This systems uses continuous perfusion, creating a stable environment for the cells, without any manual operations. Inject up to 10 different liquids. Program injection sequences and automate your experiments for better reproducibility. Suitable for 3D cell culture and dug screening.
The MicroSlides are designed to avoid applying shear stress on your cells. The cells are not directly put into the flow.
COMPATIBLE ORGANISMS
Adherent mammalian cells
Yeasts
Worm embryos
COMPONENTS LIST for cells assays on chip
Microslide designed for cell culture
Setup diagram to perform live cells assays on chip
A bubble trap can be added just before the MicroSlide to make sure that air bubbles don’t enter the chip.
It is also possible to perform a medium switch in order to expose the cells to different drugs or conditions. Check out our dedicated application note for this specific setup.

How to use the cell and biology pack for your cells assays on chip
1
Before starting the experiment, rinse the MicroSlide, the reservoirs and all the tubes and connectors with 70% ethanol to ensure sterility. Please make sure to perform all the following steps under a biosafety hood to avoid contamination.
2
Fill the reservoir with the culture medium and connect the reservoir to the flow controller.
3
Connect the reservoir to the MicroSlide.
How to fill the microslide
1
Once the MicroSlide is connected to the Perfusion Pack, tilt the device as shown on the picture. Using the Elveflow Smart Interface Software, activate the pump until all three wells are ¼ filled then shut off.
2
Add 10- to 30 uL of sample to each well with a micropipette.
3
Remove the adhesive liner from the MicroSlide, and seal it with the lid. Use thumb pressure to seal the lid.
How to perform cell culture on chip
During the experiments, the MicroSlide and the reservoirs can be placed inside an incubator or environmental chamber, while the OB1 and flow sensor stay outside. Use longer pieces of tubing in order to place the instruments outside the incubator.
