Description

Chromium-51 is a radioactive isotope of chromium, supplied as sodium chromate (Na₂⁵¹CrO₄) in a sterile aqueous solution suitable for diagnostic and research use. This product is essential for precise medical diagnostics and advanced materials research, offering a reliable tracer for studying red blood cell survival, gastrointestinal protein loss, and chromium metabolism. It is primarily required by clinical diagnostic laboratories, nuclear medicine departments, and research institutions conducting studies in hematology, oncology, and environmental science. Our Chromium-51 CAS NO 14392-02-0 is manufactured under stringent quality controls to ensure consistent performance and safety.

Application

• Red Blood Cell (RBC) Survival Studies: Used as a radioactive label (⁵¹Cr) to measure the lifespan and sequestration sites of erythrocytes in clinical diagnostics.
• Gastrointestinal Protein Loss Assessment: Employed in the diagnosis of protein-losing enteropathies by tracking the clearance of ⁵¹Cr-labeled albumin.
• Platelet Survival and Localization: Serves as a tracer for in vivo kinetic studies of platelet lifespan and organ distribution.
• Oncology Research: Utilized in laboratory research for studying tumor vascular permeability and the efficacy of chemotherapeutic agents.
• Industrial Tracer Applications: Applied in non-medical fields for corrosion studies, wear measurement in machinery, and tracing in chemical process engineering.
• Environmental Science: Used as a tracer in hydrological studies to monitor groundwater flow and sediment transport.
