Microinjection

  1. Setting up the WPI PicoPump
    September 03, 2020
    Designed to simplify intracellular injection and a variety of other micro­in­jec­tion tasks, WPI’s PicoPumps (PV830 and PV820) use precisely regulated pres­sures for se­cur­ing cells and injecting them with fluid. Injected volumes range from picoliters to nanoliters. Separate ports supply positive and negative pressure—pos­i­tive pressure for high-pressure ejection, and suction for supporting the cell or for filling the pipette from the tip. In this quick series, you can see how to setup a PicoPump. 1. What's Included with a PV Pump In this first video (#1) you can see all the components of the system as they unpack the system.  
  2. Popular UMP3 Injector is Not Your Ordinary Syringe Pump
    July 13, 2020
    [by Alec Dickson] Easy to Configure Using the SmartTouch Interface The UMP3 UltraMicroPump is easy to configure using the SMARTouch interface. It is pre-programmed for popular microsyringes and allows for user-defined syringe parameters, too. This ensures nearly universal compatibility. You can control up to two pumps, either simultaneously or independently, and the optional foot switch means hands-free operation. You can instantly verify actual injection volume on the graphical display. You can even use the touch screen while wearing gloves. Ensure Reliable Injections of Small Volumes The extremely fine thread-pitch of the UMP3 drive shaft ensures reliable injections
  3. CardioPhys ECG is Perfect for Affordable Cardiotoxicity Testing in Small Animals
    May 18, 2020
    [by Mikaël Berrou] CardioPhys™ and Cardiotoxicity When a new drug is discovered with an effect against a pathology, a natural public demand would ask to administrate it immediately. Although the new drug may be beneficial in many aspects, that new molecule could potentially have side effects that need to be evaluated. The most important potential side effect is cardiotoxicity. What is Cardiotoxicity? Cardiotoxicity is the damage to the heart by harmful chemicals (www.nccn.org/patients/resources/life_with_cancer/managing_symptoms/cardiac_toxicity.aspx), and its evaluation ha

  5. 8 Good Reasons to Choose the MICRO-ePUMP Microinjector for your Applications
    April 10, 2020
    Do you need a precision microinjector with an integrated pressure source for injections in the picoliter range? WPI’s new MICRO-ePUMP, which is comparable to the Ependorf Femtojet, is a portable solution for injecting DNA, RNA and proteins, as well as pre- and post- implantation in embryos. Whether you are doing disease modeling with zebrafish or viral research for SARS-CoV2, the MICRO-ePUMP has much to offer. Here are eight good reasons to choose the MICRO-ePUMP for your applications.   Convenient internal pressure source The convenient internal pressure source i
  6. Genetic Transfer (viral or non-viral vector) Using Microprocessor-Controlled Injector
    March 02, 2020
    With the first approved human gene therapy trial in 19891 (Rosenberg, et.al.), gene therapy has come a long way in modern medicine and is making inroads in clinics and the market in general.2,3 2017 was an important year for gene therapy when Luxurna, the first human gene therapy drug for an inherited retinal dystrophy, was approved by Food and Drug Administration (USA).4 Now several drugs are undergoing clinical trials. With an estimated $11 billion (USD) market in the next 10 years, both clinical trials and the pharmaceutical industry are expected to benefit immensely from gene therapy.5 With improved use of viral vectors (Adeno-associated virus (AAV), adenovirus, lentivirus, retrovirus, HSV) or non-viral vectors, research and clinical trials on the development of therapeutic genes have witnessed great
  7. New Technology Makes Microinjection More Reliable, Repeatable and Affordable
    January 24, 2020
    Microinjection is the process of transferring genetic materials into a living cell using glass micropipettes or metal microinjection needles. Glass micropipettes can be of various sizes with tip diameters ranging from 0.1 to 10 µm. DNA or RNA is injected directly into the cell’s nucleus. Microinjection has been successfully used with large frog eggs, mammalian cells, mammalian embryos, plants and tissues. Microinjection has been expensive, can be a slow process and requires skilled personnel, but new technologies are making it even more reliable, repeatable and affordable. Pronuclear injection, inserting DNA or RNA into the nucleus of a fertilized oocyte to create transgenic organisms, lets researchers study the role of particular genes. This horizontal gene tr
  8. WPI's NanoFil: Injection of Sub-Microliter Volumes in Animal Research
    August 21, 2019
    Are you looking for a microliter or sub-microliter and high precision syringe that holds needles as small as 36 gauge (G), in addition to having the capability to connect to quartz tubing? WPI’s NanoFil is the answer. We offer NanoFil syringes with NanoFil needles or the option to connect the NanoFil syringe to quartz tubing to use in research studies, mainly involving sub-microliter volume injections into animal tissues. Why Select WPI’s NanoFil (Syringe and Needle) System? Low Dead Volume The dead volume of NanoFil's is minute or neglig
  9. Researcher Shares Video of MICRO-ePORE™ Assisted Cell Penetration
    August 02, 2019
    The new WPI MICRO-ePORE™ pinpoint cell penetrator is a simple and versatile system that can be used to facilitate microinjection of a diverse array of compounds and biomolecules into oocytes and pre-implantation stage mammalian embryos. Patent pending Flutter Electrode Technology assists in small, clean, precise membrane penetration without tearing or damaging the membrane. It results in substantially increased viability of embryos. In this quick video, Dr. Pelczar from the Center for Transgenic Models in Switzerland demonstrates the ease o
