Description

Bectumomab is a monoclonal antibody-based pharmaceutical compound, specifically a murine anti-CD19 antibody. This product is of critical importance in the development of targeted immunotherapies and diagnostic agents for hematological malignancies. It is primarily needed by pharmaceutical R&D departments, biotechnology firms, and clinical research organizations focused on oncology and immunology.

Application

• Primary component in the research and development of radioimmunotherapy (RIT) conjugates.
• Key reagent for targeting CD19 antigen in preclinical studies of B-cell lymphomas and leukemias.
• Used in the synthesis and formulation of investigational new drugs (INDs) for clinical trials.
• Critical for developing in vitro diagnostic assays and imaging probes.
• Essential material for academic and industrial research into antibody-drug conjugates (ADCs).
• Used in pharmacokinetic and biodistribution studies of monoclonal antibodies.

Quality Control

Our Bectumomab is produced and tested under strict quality management systems to ensure it meets the high standards required for pharmaceutical research. Each batch undergoes rigorous analytical testing including purity assessment, activity testing, and sterility checks where applicable. Certificates of Analysis (COA) detailing specific results for identity, purity, and potency are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -80°C to avoid repeated freeze-thaw cycles. This product is hygroscopic (moisture-sensitive) and must be handled in a controlled, dry environment.
