Optimized, in vitro workflow to identify compounds with vasoactive properties
In vitro models have employed two common methods to quantify changes in endothelial barrier integrity: transepithelial/transendothelial electrical resistance (TEER) and tracer compound permeability.1 TEER is a non-invasive method that quantifies changes in electrical conductance to measure confluency and barrier integrity. Tracer compound permeability uses molecules of defined molecular weights to measure the size exclusion capacity of cell barriers (e.g., 4 kDa FITC-dextran or FD4).1 Using the EVOM™ Manual (EVOM-MT-03-01) with the EndOhm TEER electrode and cell culture permeable supports, this application note describes how to non-invasively evaluate endothelial barrier integrity after cytokine treatment and provides a method to identify vasoactive compounds that have the potential to induce vascular injury. Tracer compound permeability studies...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 -
