Description

Pregnancy-Specific Beta 1-Glycoprotein (PSG1) is a high-purity biochemical reagent and a key placental protein with significant immunomodulatory functions. Its primary value lies in its role as a critical research tool for studying maternal-fetal immunology, pregnancy-related disorders, and as a potential biomarker. This product is essential for researchers and developers in the fields of immunology, reproductive biology, diagnostic assay development, and biopharmaceutical research.

Application

• Biomedical Research: Fundamental studies on maternal immune tolerance, fetal development, and placental function.
• Diagnostic Development: Used as a reference standard or antigen in the development of immunoassays (ELISA, CLIA) for monitoring pregnancy health.
• Therapeutic Research: Investigation into its immunoregulatory properties for potential applications in autoimmune and inflammatory conditions.
• Quality Control: Serves as a critical raw material for the quality control and calibration of commercial diagnostic kits targeting pregnancy-specific proteins.
• Cell Culture & Immunology: Used in *in vitro* studies to assess its effects on immune cell proliferation and cytokine production.

Quality Control

Our Pregnancy-Specific Beta 1-Glycoprotein is produced and handled under stringent quality systems. Each batch undergoes comprehensive analytical testing including purity assessment by electrophoresis (SDS-PAGE) and HPLC, identity confirmation via immunological methods, and endotoxin testing. A detailed Certificate of Analysis (COA) documenting purity, biological activity (where applicable), and safety parameters is provided with every shipment to ensure it meets the exacting standards required for research and diagnostic applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a dry environment before opening to prevent condensation and moisture uptake. Aliquot into working stocks to avoid repeated freeze-thaw cycles.
