Analytical Development

Bioworkshops has established a battery of in-house analytical platform methods that meet the requirements of physical and chemical analysis, biological activity analysis or safety testing in all stages of biological products from preclinical research to cGMP production. Our researchers have extensive experience in analytical method development and validation.

The analysis platform includes Thermo Orbitrap Exactive HF-X, Protein Simple Maurice, SCIEX PA800 Plus, Waters H-Class UPLC, Thermo Vanquish UHPLC, Thermo CAD detector, Octet intermolecular interaction instrument, MD M5e microplate reader, and Roche 480 qPCR instruments. With this advanced equipment Bioworkshops is able to provide develop and validate analytical methods for comprehensive product characterization, in-process testing, and finish product testing for biologics such as monoclonal antibodies, bi-specific antibodies, fusion proteins, and ADCs.
