Critical Reagents Management

Mosaic provides the tools to maintain the supply and manage the quality of critical reagents for drug development

Mosaic software for critical reagents management

Reagents are considered ‘critical’ if their variation can have a significant effect on the assay outcome. Critical reagents are one of the most expensive parts of a screening process so it is essential they are managed optimally.

Critical reagents are very varied and often have a limited lifetime. They include binding proteins, aptamers, antibodies or conjugated antibodies, positive and negative controls, or reference standards.

Mosaic software is ideally suited to critical reagent management. It accurately tracks all sample types throughout their lifetime, including lot parentage, freeze/thaw cycles, expiry dates, stock levels and disposal, plus automatic inventory updates – all backed by a full audit trail.


Mosaic supports critical reagent management through:

Ensuring consistency and accountability by recording actions such as thawing, diluting, aliquoting and re-freezing in an audit trail
Tracking lot-level validation status and sending email alerts for items approaching a revalidation date
Monitoring inventory levels and sending email alerts when levels get low
Managing any container type used for reagent storage to ensure an accurate inventory
Ensuring users can find existing reagent stocks using robust search, rather than ordering duplicates
Controlling access to:
- which reagents may be requested, and which are reserved
- storage locations
Comprehensive storage management – including tools to:
- accurately model the entire hierarchy of sample storage
- identify appropriate free space for reagent storage
- provide reports and visualisation on freezer usage
- store and retrieve samples in bulk
Making it easier to manage, find and share materials by recording data consistently using controlled vocabularies and validated data entry
- file attachments and hyperlinks capture certificates of analysis and datasheets
Managing and tracking the requesting and delivering of reagents
Ensuring reagents are labelled accurately by integrating label printing
