 Setting Up & Running a Test 

Overview 

As  a  user  of  the  MechanoCulture,  you  are  likely  to  develop  your  own  test  preparation  and 
execution protocol, but there are several elements that are common to most users. This manual 
will  not  cover  cleaning,  disinfecting,  sterilization,  cell  seeding,  reagents,  and  a  number  of  other 
topics. 

The protocol below should be used for running new test sequences. To re-run existing sequences 
on  new  specimens,  simply  power-up  the  device,  ensure  the  system  has  been  reset,  mount 
specimens, and press the push button to execute the test. 

Attach the Sterilized Membrane to the Test Device 

See Appendix C for details and images. 

Plug  in  Control  Box  Power.    Connect  Control  Box  and  Test 
System 

Program the Device (if needed) 

Connect the Device to the PC via USB 

Launch the MechanoCulture Software 

Generate a Test Sequence 

Upload Test Sequence to Device 

Reset the system (hold down the button for 5 seconds) 

See comments in Section 4 for details on actuator reset, actuator offset, and well plate pre-
stretch. 

Add Cell Media and Cells.  Culture to Develop Adhesion 

Be sure to set the well plate/carrier assembly on a clean surface so as not to smudge the exterior 
of the membrane. 

Execute Test 

To execute the test sequence, simply press the push button once.  To pause the sequence, press 
the  button  again  at  any  point.    Once  this  has  been  accomplished,  power  can  be  removed  and 
then restored without affecting the test protocol.  To restart the test, press the button once more.  
To reset the device, press and hold the button for 5 seconds.
