EVOM™ Auto, with both 24 and 96 HTS multiwell plate capability, is a high throughput screening (HTS) platform offering fast, noninvasive sample scanning by comparing electrical resistance measurements (transepithelial/transendothelial electrical resistance: TEER). TEER measurement experiments are simple to set up and less time consuming than more complex molecular studies. TEER measurement can be used as the primary scanning method to identify any physiological changes that can then be further evaluated by other methods. EVOM™ Auto can capture TEER measurements in 24 and 96 HTS multiwell plates from Corning, Millipore, or MatTek. The sample preparation time in these HTS plates is efficient, allowing for fast, multi-channel pipetting options.
The EVOM™ Auto autosampler ships with a red electrode array lock in place to prevent the electrode array connection port from moving during transit. Here you can see how to easily remove it without damaging the lock or the autosampler...more

World Precision Instruments' (WPI) legacy Robotic Epithelial Measurement System (REMS) and the new advanced, upgraded version of REMS, EVOM™ Auto, are high-throughput, automated transepithelial/transendothelial electrical resistance (TEER) measurement systems. These robotic systems, combined with EVOM™ technology, expedite TEER measurements.
A 96-well plate can be read within a few minutes using an automated TEER measurement system versus using a manual TEER measurement system, which can take up to 90 minutes to read a single 96-well plate. Manual systems require a user to move the electrode from one well to another and perform the rinsing in between, if needed. (Rinsing of the electrode while reading through a number of samples helps to prevent sample cross-contamination.) As automated systems measurements and rinsing are controlled by robotics, manual handling time is eliminated. Additionally, automated systems offer better measurement...more

Introduction
In the process of ‘cell cycle’, cells grow and divide into two genetically identical daughter cells. It is regulated by a complex signaling pathway which keeps cell homeostasis by regulating cell division and DNA duplication1. On the other hand, because cancer cells grow and divide indefinitely out of cell cycle control, anti-mitotic drugs are used to suppress abnormal proliferation...more -

Introduction
Cytotoxicity refers to the degree of damage to cells.
caused by chemical substances or physical factors. Measuring it through cytotoxicity assay is essential for drug development and biological research. Cells undergo complex signaling pathways that causes various cell death processes such as apoptosis, necrosis, and necroptosis. However, most cytotoxicity assays...more -

EVOM™ AutoLCI Automated Live Cell Imaging System
An integrated live cell monitoring system for stable imaging of suspension cells in immunological research
As white blood cells responsible for immune function are suspension cells that travel along blood vessels, immunology studies often use various suspension cell lines originating from white blood cells. Dealing with suspension cells, unlike adherent cells, slight movement of a plate when locating it on the microscope causes the cells to float. Aside from the problems caused by temperature and CO2 instability, it is in fact not possible to use a traditional microscope to monitor cells in real time. Therefore, in order to stably monitor suspension cells, a live cell imaging device such as EVOM™ AutoLCI that operates...more -
