What is the HCPedia?

HCPedia® is a knowledge platform developed and maintained by Alphalyse to identify and understand host cell proteins (HCPs) in biologics. It combines robust, reproducible LC-MS data with expert annotations to provide our clients with the most accurate picture of residual proteins in biologics.
The HCPedia® includes:
- Thousands of HCPs identified by advanced LC-MS (Liquid Chromatography-Mass Spectrometry)
- Functional annotations of HCPs and their impact on drug products
- A curated library of scientific references, case examples, and analytical trends
Whether you are investigating a specific HCP, troubleshooting a purification issue, or evaluating ELISA coverage, Alphalyse can use HCPedia to provide the knowledge for informed, data-driven decisions.

The purpose of HCPedia
Designed for scientists, QA teams, and CMC professionals, HCPedia® provides you with a deeper understanding of HCPs and their role in drug development, empowering you to make informed decisions.
HCPedia® helps you:
- Optimize purification strategies by identifying persistent or critical HCPs
- Evaluate up- and downstream manufacturing processes
- Understand the biological function and risk profile of individual HCPs
- Strengthen regulatory submissions with detailed HCP profiles
- Benchmark your results against known datasets to detect trends or outliers
Alphalyse uses HCPedia® to:
- Identify recurring HCPs across different drug types and expression systems for faster troubleshooting
- Support R&D in developing new services and improving analytical protocols
- Enhance internal quality control and ensure consistency in reporting
- Provide customized, data-backed guidance to clients
- Develop tailored analytical strategies
