GenEx – the ultimate tool for qPCR data analysis

GenEx was the first commercial software developed for qPCR, and has since then become market leader with few thousands of users and several thousands of publications using GenEx. Sup- ported by all leading qPCR instrument manufacturers GenEx has batch import and corrects for inter-run variation. During pre- processing missing values are imputed, outliers are handled, and data are optimally normalized. Absolute quantification includes determining limit of detection, limit of quantification and dynamic range. All parameters are determined with confidence ranges in line with CLSI, CEN and ISO guidelines. Expression data are ana- lyzed with univariate methods including t-test, non-parametric methods and various ANOVAs with appropriate corrections for multiple testing ambiguity or multivariate methods including hierarchical clustering, Principal Component Analysis (PCA), Self- Organizing Map (SOM), Artificial Neural Network (ANN), Support Vector Machines (SVM), and many more. All analyses are easily per- formed with few clicks with the mouse using intuitive workflows that generate results that are readily interpreted in a biologi- cal context. At this lunch seminar, we will present GenEx and exemplify how easily multiple run files are in imported, measured data pre-processed, and how data are interactively analyzed using dynamic PCA to reveal key expression pathways and correlations across samples. All participants will receive FREE GenEx license for limited time.

Methods to determine limit of detection and limit of quantification in qPCR

Abstract:  Quantitative Real-Time Polymerase Chain Reaction, better known as qPCR, is the most sensitive and specific technique we have for the detection of nucleic acids. Even though it has been around for more than 30 years and is preferred in research applications, it has yet to win broad acceptance in routine practice. This requires a means to unambiguously assess the performance of specific qPCR analyses. Here we present methods to determine the limit of detection (LoD) and the limit of quantification (LoQ) as applicable to qPCR. These are based on standard statistical methods as recommended by regulatory bodies adapted to qPCR and complemented with a novel approach to estimate the precision of LoD.
