Product Overview
Polyethyleneimine (PEI), branched, with a molecular weight of 600 and 99% purity, is a highly efficient polycationic polymer known for its exceptional amine density and water solubility. This grade is synthesized through controlled polymerization, ensuring consistent branching and molecular weight distribution. The high purity level minimizes impurities, making it suitable for sensitive applications where reactivity and reliability are critical. Its viscous liquid form allows for easy handling and precise dosing in laboratory settings. The branched structure enhances its ability to form complexes with anionic molecules, providing superior performance in polymer synthesis, gene transfection, and surface functionalization. The product is stable under standard storage conditions and maintains its properties over extended periods when stored correctly. Its versatility stems from the balance between molecular weight and branching, which optimizes its interaction with various substrates without compromising solubility or reactivity.
FAQs
1. What is the difference between branched and linear polyethyleneimine?
Branched PEI has a highly irregular structure with tertiary, secondary, and primary amines, offering higher amine density and better solubility compared to linear PEI, which has a more uniform chain structure.
2. Can this grade of PEI be used for gene delivery applications?
Yes, the branched structure and molecular weight of 600 make it effective for gene delivery due to its ability to condense nucleic acids and facilitate cellular uptake.
3. How should this product be stored to maintain stability?
Store in a tightly sealed container at room temperature, away from moisture and direct sunlight, to preserve its chemical properties and prevent degradation.
4. Is this PEI compatible with aqueous solutions?
Yes, it is highly soluble in water and forms stable solutions, making it suitable for aqueous-based applications without requiring organic solvents.
5. What alternatives exist for applications requiring lower molecular weight PEI?
For lower molecular weight needs, consider PEI with MW 250 or 423, which offer different viscosity and amine density profiles while maintaining high purity.
