Polyethylene Glycol 2000 (PEG 2000) is a versatile, water-soluble polymer used extensively across biochemical, molecular biology, and chemical synthesis workflows. Offered as a highly pure white powder (Catalog #B2010146, 50 g), PEG 2000 supports a wide range of research applications, from macromolecule stabilization and surface conjugation to modifying solvent properties and enabling crowding in biomolecular studies. Its defined average molecular weight (1900–2200 g/mol) ensures predictable behavior in formulation, precipitation, and nanoparticle encapsulation protocols.

Manufactured to stringent biotech-grade standards, this PEG offers dependable batch-to-batch consistency with minimal impurities. Its multifunctionality includes crowding-agent behavior for enzyme kinetics, enhancement of protein solubility, and role as a steric shield in conjugate designs. PEG 2000’s high biocompatibility and ease of handling make it a staple for formulation development, protein chemistry, and molecular reagent formulation. Bulk quantities and custom packaging are available to support both routine lab use and high-volume production. Shelf-stable at room temperature, it ensures long-term accessibility and performance.

Why researchers choose this product:

  • High-purity, biotechnology-grade polymer ensures reproducible results
  • Highly soluble and versatile—ideal for stabilization, conjugation, crowding, and formulation
  • Well-defined molecular weight facilitates predictable behavior in complex systems
  • Convenient powder format for accurate dosing and long-term stability
  • Bulk and custom-size options support both routine and large-scale research needs

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