Ecocyte Bioscience offers a weekly delivery service of Xenopus laevis oocytes for expression studies. Our goal is to help your lab streamline your internal processes and spend more time researching and less time preparing.

We guarantee highest oocyte quality and on time delivery. Our oocytes are defolliculated and are ready to use for mRNA or cDNA injections.

Based on our deep scientific background and the cooperation with our customers we could improve our products and services to fulfill the growing requirements of modern research.

 We have used Ecocyte Bioscience (Germany) grade I oocytes in my lab for over a year to express various ligand-gated ion channels for electrophysiological experiments. These are easily maintained for 5-8 days, and expression is routinely very high for WT and mutant channels and also for channels carrying non-canonical amino acids. I really appreciate the direct line of communication we have with helpful Ecocyte Bioscience lab and office staff.

 The Ecocyte oocyte service offers ready to use cells that can be immediately injected with cDNA or cRNA. Hence, we can spend more time working with our favorite receptors. We ordered cells with Ecocyte for many years now and are satisfied with the overall quality of the oocytes.

Running electrophysiology labs in the US and Europe for nearly a decade, I’ve frequently found myself without ready access to animal facilities, nor sufficient staff to perform regular surgeries. So, ordering from Ecocyte has truly made my research possible. Oocytes are nearly always perfect quality, and arrive ready to inject or record. On the rare occasions when we’ve noticed a problem, support staff has responded immediately, usually at no cost to us. And they’ve accommodated every schedule change, even when our experimental plans evolve on very short notice. I can’t imagine working without them!

We have been ordering Xenopus laevis oocytes via the mail ordering service on a weekly basis for some time. The oocytes are ready-to-use and of good quality for e.g. protein expression experiments. The ordering is very easy, and delivery is reliable. I would highly recommend Ecocyte to anybody interested in working with Xenopus oocytes. 

Allan Beck Christensen, PhD, Associate Director, Biology 

My colleagues and I have been receiving oocyte deliveries from Ecocyte for the past two years. The service is always reliable and the oocytes are ready to inject as soon as they arrive. Despite being in transit for 2 days on their way to us in the UK, they have remained viable for recording 5 days post injection. I would highly recommend Ecocyte if you are using oocytes in your research!

We have been using Ecocyte as a provider for oocytes for 4-5 years with on average 2000 oocytes a month. We are a relative small user group with 5-7 people using the oocytes. The oocytes provided by Ecocyte is high quality, which we use for both electrophysiology and LC/MS based import assays. We inject the oocytes with cRNA the day they arrive, and they are ready to use 3 days after. Ecocyte provide fast shipment, and can deliver oocytes two times a week. We order in the morning the day before we need the oocytes, and they arrive normally before 12 the following day. If any problems occur with the shipment and the oocytes therefore not arrive on the correct day we get a full refund (twice a year or something).

Our service is:

  1. Time effective: Fast and reliable – express delivery; please order until 9:00 am on Monday or Wednesday.
  2. Quality effective: Continuous quality – due to optimized procedures Ecocyte guarantees similar quality of oocytes from batch to batch; stop quality changes due to preparation variabilities, non optimized animal facility properties or seasonal changes.
  3. Cost effective: no payments for animal facility, employees for animal care and preparation; no costs in times you are not using oocytes; calculate your research costs only basis of research; plan your budgets correctly.
  4. Work effective: no paper work for applications for animal experiments necessary; set your order easily via email, fax or phone; do not waste students or PHD’s for work on Xenopus.
  5. Space effective: no additional room for animal care and preparation; use your rooms for more science.
  6. Animal effective: Ecocyte serves very economically between 10 and 20 research groups from one Xenopus preparation; stop doing a preparation for only 50 or 100 oocytes the week; let’s reduce lab animals substantially.
