Description

Crystalbumins CAS NO 9066-83-5 is a high-purity, crystalline form of albumin, a fundamental plasma protein. This refined grade is critical for applications demanding exceptional consistency, stability, and low endotoxin levels. It serves as a vital raw material and functional component for manufacturers in the biopharmaceutical, diagnostic, and advanced research sectors.

Application

• Biopharmaceutical Formulation: Used as a stabilizer and excipient in therapeutic proteins, vaccines, and other biologic drug products.
• Cell Culture & Diagnostics: Acts as a nutrient and carrier protein in serum-free cell culture media and as a component in various diagnostic assay kits and reagents.
• Biochemical Research: Serves as a standard in protein quantification assays (e.g., Bradford, BCA) and as a blocking agent in immunoassays like ELISA and Western Blotting.
• Medical Device Coating: Employed to create biocompatible surfaces on medical implants and devices to improve hemocompatibility.
• Nutraceutical & Cosmetic Ingredient: Utilized in high-end skincare formulations for its moisture-binding properties and in specialized nutritional supplements.

Quality Control

Our Crystalbumins are manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for purity, identity, and biological activity. A comprehensive Certificate of Analysis (COA) detailing parameters such as protein content, purity (by electrophoresis), endotoxin levels, and bioburden is provided with every shipment to ensure traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture.
