As research grants become more performance-based, institutions are upgrading to higher-sensitivity and multiplex-ready assays to publish competitive findings.

 

Hospitals and Diagnostic Laboratories

Hospitals adopt protein assays mainly for diagnostic applications , including enzyme-level profiling, disease biomarker detection, and therapeutic monitoring. Pre-formulated kits with minimal prep time and robust accuracy are preferred.

Diagnostic labs, especially those supporting oncology and metabolic disease testing, are beginning to integrate semi-automated assay systems that enable faster turnaround without sacrificing sensitivity.

 

Contract Research Organizations (CROs)

CROs act as outsourced research partners for pharma and biotech companies. They demand scalable, validated assay systems that can be easily integrated into GLP/GMP-compliant workflows.

These firms often operate across multiple therapeutic areas, necessitating access to a wide catalog of assay formats with fast lead times and global logistics support.

 

Use Case Scenario

A tertiary care hospital in South Korea partnered with a local biotech firm to monitor HER2 protein expression levels in breast cancer patients. Using a multiplexed fluorescence-based protein assay kit, the clinical lab was able to process over 500 patient samples weekly with >98% accuracy. This enabled faster patient stratification for targeted therapy while reducing sample re-testing by 35%.

The hospital reported a 20% improvement in turnaround time for HER2 status confirmation, directly impacting therapeutic decision-making.
