Sino Biological launches site-specific labeled proteins to aid cell surface research

Cell surface proteins play key roles in immune signaling, cell adhesion and tissue maintenance, making them important targets for therapies and diagnostics.

Researchers need reliable tools to detect and study these proteins, often relying on labeled recombinant versions for flow cytometry, cell sorting and binding assays.

Site-specific labeling attaches tags at defined amino‑acid positions, preserving the protein's natural shape and activity while providing consistent labeling ratios.

Sino Biological now offers a portfolio of such site‑specifically labeled recombinant proteins, designed to retain native conformation, high stability and functional activity for use in target validation and therapeutic discovery.
