Description

Mammary Gland, Ext. is a biologically derived extract standardized for bioactive peptides and growth factors associated with mammary tissue physiology. It serves as a specialized research-grade material for in vitro studies of lactation biology, epithelial cell differentiation, and hormone-responsive signaling pathways. This product is essential for pharmaceutical R&D laboratories, academic biomedical research centers, and contract development organizations focused on reproductive endocrinology, regenerative medicine, and nutraceutical formulation. Mammary Gland, Ext. CAS NO 85883-82-5 supports high-fidelity physiological modeling where native tissue-derived complexity is required beyond recombinant single-protein systems.

Application

• In vitro mammary epithelial cell culture and functional differentiation assays
• Development of lactogenic activity screening platforms for hormonal or botanical modulators
• Support matrix for 3D mammary organoid and mammosphere formation studies
• Research reagent in studies of prolactin receptor signaling and STAT5 activation pathways
• Component in specialized serum-free media formulations for primary mammary cell expansion
• Reference material for biomarker discovery in breast development and involution research
• Preclinical evaluation of galactogogue candidates in translational lactation models
• Quality control standard for analytical method validation in tissue-derived biologics

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. Each batch is tested for sterility (USP <71>), endotoxin levels (<5 EU/mg by LAL assay), protein concentration (BCA method), and identity confirmation via SDS-PAGE and Western blot against conserved mammary-specific markers (e.g., β-casein, whey acidic protein). Testing adheres to ISO 9001-certified manufacturing protocols and supports GLP-compliant research environments.

Storage

Preserve in a tightly closed container, protected from light. Store at –20°C for long-term stability (recommended for up to 24 months). For short-term use (≤4 weeks), store at –5°C to –15°C. Avoid repeated freeze-thaw cycles. Keep desiccated; protect from moisture exposure during handling.
