Description

Technetium Tc 99M-Ethylenedicysteine is a radiopharmaceutical diagnostic agent, a complex of technetium-99m with ethylenedicysteine. This compound is critical for non-invasive diagnostic imaging in nuclear medicine, providing high-quality images for functional assessment. It is primarily required by radiopharmacies, nuclear medicine departments, and research institutions for renal and hepatobiliary imaging procedures.

Application

• Renal Scintigraphy: Primary diagnostic agent for dynamic renal imaging to evaluate kidney function, perfusion, and drainage.
• Hepatobiliary Imaging: Used for functional imaging of the hepatobiliary system, including liver and gallbladder.
• Renal Transplant Evaluation: Assessment of perfusion and function in transplanted kidneys.
• Detection of Urinary Tract Obstruction: Functional diagnosis of obstructive uropathy.
• Research & Development: Used in preclinical and clinical research for developing new diagnostic protocols.
• Radiopharmaceutical Kit Preparation: Supplied as a key component or precursor for the preparation of sterile, pyrogen-free diagnostic kits.

Quality Control

Our radiopharmaceutical products are manufactured and tested under strict GMP (Good Manufacturing Practice) conditions to ensure the highest standards of purity, sterility, and apyrogenicity. Each batch undergoes rigorous quality testing, including radionuclidic purity, radiochemical purity, pH, sterility, and bacterial endotoxin tests. Certificates of Analysis (COA) detailing all release specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. Due to its radioactive nature and specific chemical properties, it must be stored and handled in accordance with local radiation safety regulations. The product is for single use in diagnostic procedures and should not be used after the expiry date/time.
