The company faced two interrelated problems in their knockout cell line production program:

Technical validation limits: Their existing protocols were not able to identify remnants of proteins left behind or
confirm complete protein removal at the level required for critical research reagents. Researchers needed absolute
confidence that the targeted proteins were knocked out completely before distributing cell lines to researchers
globally.

Communication barriers: Even with successful validation, the company experienced trouble framing these
complex results in a format that was immediately intelligible to their diverse client population. Clients were not
necessarily mass spectrometry experts but needed a working knowledge of validation results to make informed
decisions.

Stakes were high — industry and academic scientists use such knockout cell lines for experiments that drive
biological discoveries and drug development. Inaccurate results or questionable quality would undermine research
integrity and damage the company’s reputation as a provider of quality reagents.
