April 8, 2024—Streck announced the launch of its Protein Plus BCT direct draw whole blood collection tube to provide sample integrity during storage, shipping, and handling of blood samples. The tube contains a preservative reagent that minimizes ex vivo hemolysis and platelet activation in collected samples, limits the interference of proteins released from blood cells, and maintains draw-time concentrations of plasma proteins during whole blood storage at ambient temperature. It is compatible with mass spectrometry and immunoassay-based proteomic analysis and for research use only.
