Polyethylene Glycol 400 (PEG 400)

Description

Polyethylene Glycol 400 (PEG 400) Catalog B2010145 (25 g)

Polyethylene Glycol 400 (PEG 400) is a high-quality, water-soluble polymer widely utilized in biochemical and molecular biology workflows for its remarkable versatility as a solvent, stabilizer, and crowding agent. Offered as a viscous liquid (Catalog B2010145, 25 g), PEG 400 is engineered to biotechnology-grade standards, ensuring 99% purity, minimal contaminants, and reliable batch-to-batch performance. Its compatibility with both aqueous and organic systems makes it indispensable across protein stabilization studies, enzyme assays, conjugation workflows, and pharmaceutical research formulations.

PEG 400 is highly valued for its ability to modulate solvent polarity, influence macromolecular interactions, and stabilize sensitive biomolecules under experimental conditions. It is routinely used as a solubilizer for hydrophobic compounds, a reagent for precipitation and macromolecular crowding experiments, and a stabilizing component in nanoparticle and drug delivery systems. Its liquid format allows easy dosing and integration into complex formulations, while storage at room temperature makes it a convenient, shelf-stable laboratory reagent. Bulk sizes are available for extended and large-scale projects.

Why researchers choose this product:

• Biotech-grade PEG 400 with 99% purity for reproducibility
• Highly soluble, multifunctional polymer suitable for stabilization, solubilization, and formulation work
• Viscous liquid format ensures easy handling and integration
• Stable at room temperature with extended shelf life
• Bulk supply available for long-term or large-scale workflows

Indication for Use:
This product is for Research Use Only (RUO). It is not intended for human or animal therapeutic or diagnostic applications.
