Overview of qbase plus 3.2
qbase plus 3.2 is the latest iteration of the flagship quantitative PCR (qPCR) data analysis software developed by Biogazelle (now part of Danaher’s IDT division), Designed for life sciences researchers, it streamlines the analysis of gene expression data from RT-qPCR experiments, ensuring compliance with MIQE guidelines for accurate normalization and validation. The software excels in high-throughput workflows, supporting relative and absolute quantification, inter-plate calibration, and automated quality control for applications in biomarker discovery, oncology, and pharmacogenomics. With built-in support for over 100 instruments (e.g., QuantStudio, LightCycler), it processes data from formats like SDS, ED, and MACRO.
As of October 21, 2025, qbase+ 3.2 remains the current stable version, with a minor patch (3.2.1) addressing export compatibility in August 2025. Future updates are anticipated in 2026, focusing on AI-driven outlier detection.
