Antibodies

Host cell protein antibodies are critical tools for detecting and quantifying host cell proteins in biologics produced from CHO and other mammalian expression systems. These highly specific antibodies enable accurate identification of residual host cell
proteins that can impact safety, stability, and efficacy.

ICL develops and validates CHO-specific host cell protein antibodies for high-risk targets such as PLBL2, NUCB2, CTSA, and LPLA2, ensuring reliable detection that supports regulatory compliance and consistent product quality.

Trusted by biologics manufacturers worldwide, ICL’s host cell protein antibodies deliver high specificity, reproducibility, and long-term supply for process development, QA/QC, and manufacturing.
