Meet us at USP’s 7th Bioassay Workshop on Sep 25-26, 2017

Visit our booth! We will be there and demonstrate the latest version of our PLA bioassay analysis software. Feel free to approach us directly at our booth to discuss your bioassays. We are also excited to be on the Software Vendor Panel.

USP’s 7th Bioassay Workshop which is entitled "Bioassay Life Cycle Approach" will provide a perfect opportunity to discuss lifecycle methods from scientific and statistical, as well as regulatory perspectives. It will include the presentation of case studies from various stages in an assay’s lifecycle.

The workshop will take place on Sep 25-26, 2017 at the USP Headquarters in Rockville, MD, DC Area.

To register, please go to

There's another opportunity that you don't want to miss out on: Join our PLA 3.0 Super User Training in Rockville, DC Area, on...

PLA 3.0.4 SR3 and Biological Assay Package 24 are available - download now!

We are pleased to announce the release of PLA 3.0.4. SR3 as well as the Biological Assay Package 24. You can download both right here on our website.

The new Bioassay Package 24 is available as a separate download. We recommend updating your PLA to version 3.0.4 SR3 before you install this package.

If you are working with the Control Chart feature of PLA 3.0, you will find the new Bioassay Package particularly useful. We improved the data transfer into the control charts and made the labels more consistent. Also, the program now provides the EC50 value and a number of additional values for control charts. Other improvements include the improved compatibility with PLA 2.0 and the treatment of Not Calculated Tests.

SR3 is a new build of PLA 3.0.4. It is an updated version which fixes a few technical problems introduced with the initial PLA 3.0.4. It does not modify capabilities of the...

New version of Data Acquisition Module supports SoftMax Pro 7

We released an updated version of our SoftMax Pro Data Acquisition Module for PLA 3.0. The module now supports SoftMax Pro (a registered trademark of Molecular Devices, LLC) from version 3.x to 7.x. If you are using SoftMax Pro 7 and would like to import the measurement data into PLA 3.0 for an advanced analysis, then this module will be right for you. Please contact us for a quote.

The new PLA Migration & Archiving Toolkit is available now

In case you are working with PLA 2.0 or PLA 2.1, we have something you might be interested in: The new PLA Migration & Archiving Toolkit.

The Migration & Archiving Toolkit enables you to retire your PLA 2.x system completely and switch to PLA 3.0 without losing anything important. The bioassay data you accumulated in PLA 2.x over the years is a valuable asset and we want to make sure you benefit from it as much as possible.

We think that this toolkit will be most useful for many PLA users, so please take a look at the information available here on our website. You're of course welcome to talk to one of our scientific consultants about your specific situation and how the Migration & Archiving Toolkit will be able to help you.

PLA 2.0 has reached its end of life - update now!

Each major version of PLA has a lifecycle of 10 years. We released PLA 2.0 on August 30, 2006. So this version reached its end of life on August 30, 2016.

This means that after August 30, 2016 we will no longer support PLA 2.0. We will not publish any updates and will not provide bugfixes. This is because we have to allocate our resources in the most effective way. We therefore cannot provide support for older versions of PLA indefinitely.

What are your options if you still use PLA 2.0?

Of course, you can continue to work with PLA 2.0. The program will continue to function, but from August 30, 2016 onwards you will be without support, without bugfixes and without updates.

But there is another option. It is also the one we strongly recommend: You should give PLA 3.0 a try. This is the current version of PLA and it is superior to its predecessors in many ways. PLA 3.0 is available as a...

New Book on Statistical Analysis of Bioassays by Stanley N. Deming

Well-known consultant and trainer Stanley Deming (Statistical Designs, Houston, TX) just published his latest book titled "The 4PL". It is one of only a small number of current publications in this field and explains the mathematical form of the four-parameter logistic model that is the basis of many bioassays.

Support for PLA 2.0 ends in less than a year

Each major version of PLA has a lifecycle of ten years. We published PLA 2.0 on August 30, 2006. So this version will reach its end of life on August 30, 2016.

This means we will not support PLA 2.0 beyond this date. The software will most certainly still work, but we won't provide bugfixes, updates or any other form of support. The reason for this is that we have to allocate our ressources in the most effective way and cannot support older versions of PLA indefinitely.

Those users who are still working with PLA 2.0 should consider switching to PLA 3.0. Since both versions of PLA can coexist on the same computer, the transition can be gentle. It might make sense to continue using PLA 2.0 for ongoing project (especially for those who are working in regulated environments), while at the same time launching new projects only in PLA 3.0.

Important: Users with a valid PLA Upgrade...
