Analytical Methods

Dose Formulation Analysis (DFA) method development and validation

At this stage, analytical methods are developed and validated to ensure dosing formulations are administered at the intended concentration, with confirmed homogeneity and stability. Validation under GLP principles assesses accuracy, precision, linearity, specificity, and reproducibility, ensuring the integrity of dosing solutions and supporting the scientific validity and regulatory compliance of toxicology studies.

Our team designs and validates tailored analytical methods to support a wide variety of formulations, from conventional small molecules to complex biologics or advanced therapies, ensuring accuracy and reproducibility across preclinical programs. This process is essential to confirm the stability and integrity of the test item, generate reliable data, and meet the stringent requirements of regulatory submissions.

Reliable Formulations for Accurate Dosing

We develop customized formulations based on the physical and chemical properties of each test item. Our experts assess factors such as solubility, stability, viscosity, and compability with dosing routes and animal models. Once defined, the team validates the methods to confirm consistency in concentration, uniformity, and stability under specific storage and usage conditions. All procedures are executed in GLP-certified facilities, with full traceability and documentation to support regulatory submission.
