Bioassay Sciences Platform

BAS has been able to develop a platform approach to bioassays, due to our extensive experience in developing bioassays. This allows the client to quickly determine the number of dilutions, dose/response, signal detection and then use our validity criteria and SAS/JMP based scripts. A platform approach to bioassays speeds up the development timeline and simplifies the validation.

Our Mission

Platform Approach

Work with clients to provide a platform approach for modern bioassay design and report generation.

Reduce Variation

Reduce variation due to poor calculation and data handling (15-20%).

Reduce Invalids

Reduce invalid and OOS rate due to poor calculator design.

Modern Approach

Use modern statistical approaches, USP 1032/1034 aligned to relative potency determination.

Reduce Cost

Lower the cost of ownership (over SAS and other software) and maintenance of bioassays.

Improve Automation

Improve automation, data generation and tracking and trending/control of bioassays.

Simplify Process

Simplify the development, automation, reports and software validation of bioassays.

Increase Speed

Increase the speed of development by using a platform approach and modular code.

Improve Monitoring

Dramatically improve bioassay monitoring, control and tracking and trending.
