  1. Recording TEER Measurements from an EVOM2
    November 11, 2014
    The 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
  2. Using a DAM50 for EEG Recordings in Rodents
    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. For this application, you will need the following equipment: (1) DAM50 amplifier (1) MD4R micromanipulator (2) M

  5. Choosing a Cellix Pump for Microfluidics
    August 20, 2014
    The Cellix microfluidic line is complete and flexible, offering a broad range of biochips and accessories, along with three different microfluidic pumps and complete systems. By operating under continuous blood flow conditions, the Cellix platform simulates the human environment providing researchers with powerful data far beyond that available via static conditions of the petri dish before advancing to costly animal trials.  By using the Cellix solution, false leads can be eliminated earlier in the process, increasing the success rate of clinical trials and giving you the competitive edge. This solution is unique and contains everything a researcher requires to execute continuous flow, cell based assays and make informed decisions. The only fully integrated, end-to-end Microfluidics system on the market, the Cellix solution includes the platform, biochips and cell analysis software.  You can study drug effects on cell activity for cardiovascular, oncology, i

    July 21, 2014
    WPI's Nanoliter 2010 Microinjection Pump is ideal for many applications, including zebrafish, xenopus oocytes and drosophila. MICRO4, an optional microprocessor-based controller, can provide an "intelligent" and easy-to-use interface to up to four Nanoliter Injectors. Operating parameters are set with the membrane key-pad and LCD display. More Info
  8. Rodent Facemask Kits for Isoflurane Anesthesia
    July 14, 2014
    Gas anesthesia with Isoflurane is quickly becoming the standard method of general anesthesia for rats and mice in biomedical research. The advantages of using gas anesthesia for in-vivo examinations include: Fewer complications than injectable agents Allows for longer exam duration Easier administration and control Readily incorporated into existing procedures Level plane of anesthesia Minimal animal handling/Less stress No controlled substances required Quick recovery time Economical and versatile These are designed to tightly and flexibly fit on various size rodents. The optically clear masks are designed to provide access to the eyes and head of the rodent. These masks provide stability of the animal
