The LightCycler® Software 4.1 is an update to LightCycler® Software 4.05. The only difference between this updated version and LightCycler® Software 4.05 is that Version 4.1 can be operated on Windows XP. It integrates all software modules required to perform and analyze any type of experiment using the LightCycler® 2.0 Instrument.
Opening new horizons in the field of data analysis, the LightCycler® Software 4.1 maintains and expands the analysis modules for absolute quantification and melting curve analysis. Additionally, the new software integrates a dedicated relative quantification module for mono- and dual-color experiments. A module for genotyping by melting curve analysis is also part of the package. Most analysis modules automate the analysis of internal controls.
The LightCycler® Software 4.1, as well as LightCycler® Software 4.05, offers a new quality of data management, user management, and security.
