Description

Albumin (Human Blood Serum Protein Moiety Reduced) is a highly purified, modified form of human serum albumin (HSA) where the disulfide bonds have been chemically reduced. This product, identified by CAS No. 57622-87-4, is a critical biochemical reagent valued for its defined molecular state and consistent performance. It is essential for research and development in life sciences, particularly in studies requiring a non-oxidized protein scaffold or a specific redox environment. Key industries that rely on this material include pharmaceutical development, diagnostic manufacturing, and advanced biochemical research.

Application

• Biopharmaceutical Excipient Development: Used as a stabilizer and carrier protein in the formulation of sensitive therapeutic compounds, including vaccines and biologics.
• Diagnostic Assay Manufacturing: Serves as a key component in immunoassays, calibration standards, and control sera due to its consistent reduced state.
• Cell Culture & Tissue Engineering: Employed as a supplement in specialized media to support the growth of demanding cell lines and in 3D bioprinting applications.
• Biochemical Research: Acts as a standard or substrate in redox biology studies, enzyme kinetics, and protein-protein interaction analysis.
• Drug Delivery Systems: Investigated for use in nanoparticle conjugation and targeted delivery platforms where a reduced protein moiety is required for linker attachment.
• Reference Material: Provides a well-characterized standard for quality control in pharmaceutical and diagnostic industries.
