Description

Bnp-45 (Rat) is a synthetic peptide fragment corresponding to the brain natriuretic peptide sequence, identified by CAS NO 123337-89-3. This high-purity biochemical is essential for cardiovascular and renal research, serving as a critical reference standard and active pharmaceutical ingredient (API) intermediate. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and diagnostic manufacturers focused on developing novel therapeutics and assays for heart failure and related conditions.

Application

• Pharmaceutical Research & Development: As a key reference standard and intermediate in the synthesis of novel natriuretic peptide-based therapeutics.
• Biochemical Assay Development: For the calibration and validation of immunoassays (e.g., ELISA) and other diagnostic tests targeting BNP.
• Academic & Preclinical Studies: Used in cardiovascular and renal physiology research to study hormone signaling pathways and disease mechanisms.
• Quality Control & Standardization: Serves as an analytical standard for the quality control of commercial BNP-related products and APIs.
• Peptide Chemistry: A valuable building block for further chemical modification and conjugation in peptide synthesis.

Quality Control

Our Bnp-45 (Rat) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic (moisture-sensitive) nature, the product should be allowed to equilibrate to room temperature in a desiccator before opening to prevent moisture uptake. For long-term storage, consider storing under an inert atmosphere.
