Product Description

Byologic® is unique software developed in partnership with biopharmaceutical scientists to improve accuracy and efficiency in the interpretation of mass spectrometry data and to accelerate project schedules. It is used from late discovery through clinical development to define design space and product profile and it supports Multi-Attribute Method reporting. The software enables researchers to confidently characterize their product down to trace components, and reduces turn-around time by a number of weeks. Tables and figures can be exported in a variety of formats for application filings.
