Challenges in the Market

• High Equipment and Operational Costs
  The initial investment required for high-throughput patch-clamp systems and electrophysiology instruments is substantial. In China, small- and mid-sized enterprises often face financial constraints in acquiring these technologies. Maintenance costs and skilled technician requirements further elevate operational expenses. Manufacturers are addressing these challenges by introducing modular and subscription-based solutions. However, cost barriers remain a major limitation for broader adoption in academic and startup environments.

• Limited Availability of Skilled Electrophysiologists
  hERG screening demands expertise in cardiac electrophysiology and ion channel analysis. The shortage of skilled professionals in China limits assay throughput and data accuracy. Training programs for technicians and researchers are being developed but remain insufficient. Pharmaceutical companies are collaborating with universities to build specialized training pipelines. The lack of expertise slows adoption of advanced platforms and hinders large-scale implementation. Building a trained workforce is crucial for market maturity.

• Data Variability and Lack of Standardization
  Differences in cell lines, assay protocols, and instrument calibration can lead to inconsistent results across laboratories. The absence of global standardization complicates regulatory review and cross-study comparison. Researchers in China are working toward harmonizing assay procedures through international consortia. Implementation of GLP-certified validation and ISO-compliant workflows is improving reproducibility. However, complete standardization remains a work in progress, affecting overall data reliability.

• Ethical and Biological Limitations of Existing Models
  Although cell-based assays have advanced, they still lack the full physiological complexity of human cardiac tissue. hERG overexpression systems may not always accurately predict in vivo cardiac responses. Researchers are developing integrated multi-channel and tissue-engineered systems to overcome these limitations. The challenge of replicating native cardiac electrophysiology continues to drive innovation in model development. Bridging this biological gap is essential for improving translational accuracy.

• Complexity of Data Interpretation and Validation
  The sheer volume and complexity of electrophysiological data generated during hERG screening pose analytical challenges. Manual data interpretation is time-consuming and error-prone.
