Determining Criticality–Process Parameters and Quality Attributes Part III: Process Control Strategies—Criticality throughout the Lifecycle

March 1, 2014

This series presents a practical roadmap in three parts that applies scientific knowledge, risk analysis, experimental data, and process monitoring throughout the three stages of the process validation lifecycle. In Parts I and II, risk analysis and process characterization studies were used to assign criticality risk levels to critical quality attributes and critical process parameters, and the concept of a continuum of criticality was established. In Part III, the author applies the continuum of criticality to develop the process control strategy and move through Stages 2 and 3 of the new process validation lifecycle.

Metacomplex Formation and Binding Affinity of Multivalent Binding Partners

November 1, 2013

A study to investigate metacomplex formation in the hetero-association of a multivalent antigen, streptavidin (SA), and a bivalent antibody (Ab) using a composition-gradient multiangle light-scattering (CG-MALS) system consisting of a composition-gradient device, a MALS detector, and a UV/Vis absorption detector.

Definition of a Security Value Determined by Limulus Amebocyte Lysate Assay Targeting the Recombinant Human Epidermal Growth Factor

October 1, 2013

The correlation between limulus amebocyte lysate (LAL) assay and rabbit pyrogen test (RPT) targeting recombinant human epidermal growth factor (rhEGF) as active molecule was assessed.
