In the Varioskan LUX Multimode Microplate Reader, how is running a TRF spectrum by setting excitation at 335 nm and using emission range different from running a filter-based TRF assay? Why does SkanIT Software have the TRF spectrum option?
The TRF spectrum option is useful for spectral analysis, assay and label development, and optimization purpose. For example, when a new TRF chelate label is developed, TRF spectrum measurement can be used to analyze the spectra when a lot of label is loaded in the well.
When the TRF spectrum option is used, the sensitivity is not sufficient for actual TRF assays as the instrument sensitivity decreases by about 200-fold. Hence, the TRF spectrum option should not be used for normal TRF assay applications. For optimal results, the TRF spectrum option should be used for TRF spectral scanning but not for running actual TRF assays. Actual TRF assays must be performed using filter-based TRF optics in the LAT module.
If the Varioskan unit does not have TRF optics in the LAT module, TRF spectral scanning cannot be performed. In this case, TRF spectral scanning can only be performed using TRF-based filters.

What is the compatibility of SkanIt Software for Microplate Readers v7.1 with Windows 10 and 11?
In order to use SkanIt Software for Microplate Readers v7.1, your computer should meet minimum requirements as shown below:

SkanIt Software v7.1 has been updated to use Microsoft .Net Framework 4.8.
Microsoft .Net Framework 4.8 is not supported on Windows 10 1507 or 1511 versions (https://answers.microsoft.com/en-us/insider/forum/all/want-to-install-net-framework-48-in-window-10/4e60ed75-6fcc-4094-b14a-150c22139a49). If you're using Windows 10 version 1507 or 1511 and you want to install Microsoft .NET Framework 4.8, you first need to upgrade to a later Windows 10 version, i.e., version 1607 or later (https://learn.microsoft.com/en-us/dotnet/framework/install/versions-and-dependencies).
Note: Windows 10 version May 2019 onwards should have Microsoft .NET Framework 4.8 installed by default.
