Extended protein stability with the HEMAcollect PROTEIN Blood Collection Tube

This white paper details how the HEMAcollect™ PROTEIN Blood Collection Tube, powered by ProteoPrecision™ technology, preserves plasma protein integrity for up to 7 days at room temperature, minimizing the pre‑analytical variability that commonly affects proteomic studies. The data show significantly reduced hemolysis, platelet activation and cytokine release compared with standard EDTA tubes, supporting improved sample homeostasis during storage and simulated transport. The tube’s stabilizing chemistry maintains accurate plasma protein profiles and demonstrates direct compatibility with multiple downstream proteomic platforms, including LC‑MS/MS, Olink™ PEA and SomaLogic™ SomaScan™ assays, enabling reliable biomarker discovery and high‑quality proteomic analysis.
