When your transepithelial electrical resistance (TEER) measurement processes require 21 CFR Part 11 compliance to satisfy FDA requirements, WPI’s GxP module for use with the EVOM™ Auto is perfect. Powered by TotalLab, the software database ensured that your EVOM™ Auto TEER data is tracked and stored with appropriate electronic signatures and an extensive audit trail. EVOM™ Auto can be used to perform automated TEER measurement on both 24- and 96-well plates. In this video you can see how to prepare your data for downloading.

WPI’s EVOM™ line of transepithelial electrical resistance (TEER) measurement systems is the industry standard with thousands of citations in peer-reviewed journals spanning over 40 years. Our newest automated TEER measurement unit, the EVOM™ Auto, works with both 24- and 96-well plates, and now it is available with an optional GxP module to ensure 21 CFR Part 11 compliance to satisfy FDA requirements. In this video you can see how to run, pause, and stop an experiment.

EVOM™ Auto GxP Module is an add-on for the EVOM™ Auto Automated TEER measurement system that ensure 21 CFR Part 11 compliance to satisfy FDA requirements. The EVOM™ Auto is used for making transepithelial electrical resistance (TEER) measurements when you are testing for cell confluency or barrier integrity when you are doing drug absorption studies, tissue engineering, disease model, QC of cell-based assays and more. In this video we will create a sequence to use with an EVOM™ Auto that has the GxP module.

EVOM™ GxP compliance Module is 21 CFR Part 11 compliant software that meets the FDA's requirements for electronic records and signatures. It work with the EVOM™ Auto autosampler.  In this video we launch the EVOM™ Auto GxP software from within EVOM™ Auto GxP Client.

The EVOM™ Auto automates measurements of TEER in epithelial or endothelial monolayers cultured on 24-well or 96-well high throughput screening (HTS) plates utilizing our innovative EVOM technology, qualitatively measuring cell monolayer health and quantitatively measuring cellular confluence by reaching an increase or a plateau in tissue resistance. The autosampler has a 3-well rinse station for cleaning and stabilizing the electrodes. Now, sterile disposable rinse station inserts are available for your convenience. They fit over the 3-well base rinse station. You can simply throw out the disposable inserts with the solutions when you are changing plates. This short videos shows how easy they are to use.

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.

The WPSS01 skin stapler is an affordable, reliable solution for veterinary wound closures. A skin stapler is designed for the efficient closure of surgical incisions or wounds by applying surgical staples to the skin, reducing surgery time and time under anesthesia. Each disposable skin staple cassette contains at least thirty-five (35) 316L stainless steel staples.

Each reusable skin stapler handle is provided sterile with one disposable staple cassette already loaded into the handle. Discard the disposable staple cassette after the procedure. The reusable handle may be cleaned and resterilized (autoclave, EO) for subsequent procedures and will effectively deploy at least twenty (20) disposable staple cassettes and withstand at least twenty (20) autoclave cycles.

Let’s take a look at how to set up a Digital Rat/Mouse, Neonatal Rat Stereotaxic frame. In a few steps you will be up and running.

In 2022, the United States Food and Drug Administration (FDA) approved 37 new drugs, of which 20 were chemical entities and 17 were biologics. In 2023, drug discovery remains strong with many new advancements a result of changing landscapes in both the types of drugs that are being developed and the new and innovative assay that are being launched to evaluate drugs preclinically. Therapeutic development is still highly focused on diseases that affect large populations of people for which there are lack of effective treatments, with 2023’s most anticipated drug launches expected to be in areas of cancer, Alzheimer’s disease, cardiovascular disease, and ulcerative colitis.

If the EVOM™ Auto software switches from Resistance to TEER mode while you are selecting menu options, here's a quick tip:

Be careful when selecting Resistance mode, do not tap the background window and do not click on the side arrows.

Tapping the background window will switch you to TEER mode.

Instead, tap an option on the forefront square window to stay in Resistance mode.
