Description

Liver Extracts are a complex biological preparation derived from mammalian liver tissue, standardized to contain essential nutrients and growth factors. This product is a vital source of key components such as vitamin B12, folic acid, and amino acids, which are crucial for various biochemical and cell culture processes. It serves as a fundamental raw material and supplement in the pharmaceutical, biotechnology, and research and development sectors, where consistent quality and biological activity are paramount for successful outcomes.

Application

• Cell Culture Media Supplement: Used as a nutrient-rich additive to support the growth and proliferation of demanding cell lines in biopharmaceutical production and research.
• Microbiological Assays: Serves as a growth-promoting component in culture media for the microbiological assay of vitamins like B12.
• Pharmaceutical Formulations: Employed as an active pharmaceutical ingredient (API) or excipient in hematinic and nutritional supplement formulations.
• Biochemical Research: Provides a source of enzymes, cofactors, and undefined growth factors for studying metabolic pathways and enzymatic reactions.
• Diagnostic Reagents: Utilized in the manufacturing of diagnostic kits and reagents that require liver-derived components.
• Fermentation Processes: Acts as a complex nitrogen source to enhance yield in certain microbial fermentation processes.

Quality Control

Our Liver Extracts are manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for biological activity, microbiological purity, and chemical composition. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as vitamin B12 content, total nitrogen, moisture, and absence of specified pathogens. Production can be aligned with relevant pharmacopoeial standards (e.g., USP, EP) for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) to maintain stability and biological activity. This product is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent clumping and degradation.
