🌟 Introduction

Assay development is one of the most exciting and rapidly growing areas in biotechnology and diagnostics. Whether you’re working on biomarker assays, cell-based assays, or in vitro diagnostics (IVDs), this field sits at the core of transforming biological discoveries into actionable clinical tools. As personalized medicine and rapid diagnostics evolve, skilled assay developers are in high demand across research institutions, startups, and large pharma companies.

🧠 What Is Assay Development?

Assay development involves designing, optimizing, and validating experimental methods to detect or quantify biological targets such as proteins, nucleic acids, or small molecules. These assays support research, diagnostics, and therapeutic discovery pipelines.

Assay development scientists bridge biology, chemistry, and data analysis — turning molecular reactions into measurable signals that enable reliable clinical or research outcomes.
