Description

Fetuin is a high-purity glycoprotein, primarily sourced from fetal calf serum, known for its role in inhibiting unwanted mineralization and promoting cell attachment and growth. This makes it an essential component in advanced cell culture and biomedical research applications. It is particularly valuable for researchers and manufacturers in the biopharmaceutical, diagnostic, and life science sectors who require reliable, high-quality biological reagents.

Application

• Cell Culture Supplement: Used to promote cell attachment, proliferation, and to inhibit trypsin activity in serum-free and low-serum media formulations.
• Biomineralization Studies: Serves as a potent inhibitor of hydroxyapatite formation, making it critical for research into bone metabolism and pathological calcification.
• Protein Standard & Marker: Employed as a standard in electrophoresis and chromatography due to its well-characterized glycosylation and molecular weight.
• Diagnostic Reagent Manufacturing: Utilized as a blocking agent or stabilizer in immunoassays and other diagnostic kits to reduce non-specific binding.
• Glycobiology Research: A model glycoprotein for studying protein glycosylation, sialylation, and lectin binding.
• Stem Cell & Tissue Engineering: Supports the growth and maintenance of sensitive cell types, including embryonic stem cells, in defined culture systems.
