Analytical/Bioanalytical Method Development and Validation

Pacific BioLabs has vast experience in analytical and bioanalytical method development and validation for a variety of platforms including HPLC, LC/MS/MS, GC/MS or GC/FID, ICP/MS, and ligand binding assays (ELISA or other cell-based assays). As both an in vivo and analytical CRO, we support product development of a variety of pharmaceuticals, biologics and medical devices.  Method development and validation is an important first step to determine that analytes of interest can be reliably detected and quantified for routine sample analysis. Our team includes three lead scientists that each have over 15 years experience in method development. They will work with you to understand your needs and develop a plan for your product’s analytical development.  Based on our extensive experience with similar products and by drawing upon published literature resources, PBL can swiftly develop the most appropriate method for your product.

After method development, PBL can validate the method according to FDA, USP, EP or ICH guidelines to determine its suitability for its intended use. PBL is flexible in supporting complete or partial validations, re-validations and method transfers. PBL provides full documentation including a fully QC/QA reviewed protocol, method SOP, and report for the analyses.

The Analytical Team at PBL has developed methods for very challenging analytes including urine, brain and plasma biomarkers for glycosaminoglycan (GAG) metabolism, strontium heavy metal quantification in pig skin, and numerous drugs in simulated gastrointestinal fluids. The below links provide summaries for some of these projects and highlight the experience and capabilities of PBL’s analytical department.
