Developed for use by scientists and researchers to meet the rigors of science and industry, Panmo comes with an expanded set of fully-featured analytical, graphical, and presentation tools.

Panmo runs on 32-bit and 64-bit Linux and Microsoft Windows (XP or newer).

Optional modules are available to Microsoft Windows versions of Panmo and provide functionality for analyzing automatic microscopy data (or HCS in short) and FLIPR data. We offer these modules for Linux by special request only. Please contact us for details

For a list of features and functions, please see the Product Comparisons section below.

To request a trial copy of Panmo, please fill out the following form. We will email you a URL for downloading a trial copy of Panmo and a license file. Panmo will not work without a properly installed license file. The trial period is 15 days.

Optional Modules

Optional modules are available to work with Panmo to analyze automatic microscopy and FLIPR data. These modules are fully integrated with Panmo to form a synergistic data exploration and analysis environment.

Automatic microscopy, also known as high-content screening or HCS, produces heterogeneous, multivariate, big and messy data with lots of "junk" mixed in. Panmo is perfectly suited to sift through such data and its vast mines of information.

Three modules are available to work with Panmo:

  1. HCS image module
  2. Cell cycle analysis module
  3. Impressionist density plot module

With multiple plates of kinetic FLIPR data, there can be a plate-to-plate variability with regards to the "average" response. If this variability is large, it can obviously adversely affect the clustering of the FLIPR data.

The FLIPR module is designed to normalize a set of FLIPR data by taking out this plate-to-plate variability.

If you do not have a copy of Panmo with a valid license, please request a trial of both Panmo and optional modules here.
