The Dose-Response Analysis Package 2.0 is a powerful add-on for PLA 3.0 that delivers advanced tools to investigate dose-response relationships, whether you're working with calibration curves, spike-and-recovery studies, or curve comparisons.

New Regression Models for Greater Flexibility

The Dose-Response Analysis Package 2.0 expands your analytical capabilities with two additional regression models:

  • Hill Equation Model: Ideal for fitting non-linear response data ranging from 0% to 100%, making it perfect for binding assays or smaller datasets
  • 2-Parameter Logistic Model: Offers enhanced flexibility for describing response ranges. You can either use undiluted samples to converge the asymptotes or enter the values manually

Enhanced Interpolation & Standard Curve Validation

This release allows the interpolation of Standard responses on the Standard curve to ensure its validity. The detailed report now shows the calculated substance activity and its recovery based on the assigned concentration per step.

More Insights at a Glance

We’ve enriched the dashboard and reports with even more statistical details:

  • EC50 values are now displayed on the dashboard alongside parameter estimates for every curve fit, providing a clearer picture of assay performance at first glance
  • Model formulas and detailed parameter descriptions are now included to help you understand and compare models more effectively

Improved Usability and Workflow Enhancements

This version also brings multiple usability upgrades:

  • Attachment Support: You can now attach, view, print, and export high-resolution plots and additional files (e.g., SOPs or external data) within your documents
  • Streamlined Method Definitions: Dynamic summaries help guide you through equivalence margin development
  • Consistent Visualization: Plots now automatically align in scale for easy comparison across results
  • Refined Labels: We’ve improved the clarity of labels for suitability tests and regression parameters to simplify navigation
