ELISA Kits

Host Cell Protein ELISA kits are essential tools for detecting and quantifying host cell proteins in biologics produced from mammalian expression systems such as CHO cells. These sandwich-format host cell protein assays provide high sensitivity and specificity, ensuring regulatory compliance, product safety, and therapeutic efficacy.

By identifying residual host cell proteins that can trigger immune responses, reduce drug stability, or compromise efficacy, host cell protein ELISAs play a critical role in biopharmaceutical quality control. Advanced host cell protein assays now target high-risk proteins such as PLBL2, NUCB2, CTSA, and LPLA2, offering superior accuracy over generic host cell protein assays.

ICL’s validated host cell protein ELISA kits feature:

• CHO-specific antibodies and standards for precise host cell protein quantification
• High sensitivity for nanogram-level host cell protein detection
• Fast turnaround (<3 hours) with minimal sample interference
• Proven reliability for process development, QA/QC, and lot release

Trusted by leading biologics manufacturers, ICL provides a complete line of ELISA kits, antibodies, and purified proteins for host cell protein detection to ensure consistent biologic production, regulatory readiness, and patient safety.
