Light Engine - Turning Light into Science

Posted: Monday, April 20, 2015

If you have seen a rainbow, you have seen the visible part of the light spectrum broken out. Each color of light is actually a different wavelength of light. In scientific applications, we are often interested in only one or two wavelengths of light. For example, a muscle tissue can be stained with a dye that makes the calcium glow when a certain wavelength of light hits it. Or, a nerve cell can be stained with a dye that glows when the cell is firing.

Recording TEER Measurements from an EVOM2

Posted: Tuesday, November 11, 2014

EVOM2  is used for making manual TEER measurementsThe EVOM2 is the classic, hand-held instrument for making Trans Epithelial Electrical Resistance (TEER) measurements. The REMS system adds a robot and data recording for automated TEER measurements. There may be times when you don't have a robot, but would still like to have the data recording capabilities of the REMS system. With a little ingenuity, you can do just that. Here, we will show you how you can add data recording to your standard EVOM2.


Using a DAM50 for EEG Recordings in Rodents

Posted: Tuesday, October 21, 2014

A low-noise amplifier like the DAM50 is an excellent choice for EEG recording in rodents. WPI’s amplifiers were engineered for the bio-medical researcher. While 20-30μV of noise is common in bio-amplifiers, WPI’s DAM series amplifiers generate 0.4μV RMS (root mean squared) at 0.1-100Hz. (That’s equal to about 2μV peak to peak.) This setup shows one way such recordings could be made. The RC1 electrode works well for rats, and the EP1 is more suitable for mouse cranial application.
