Visão geral

Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion.
Application
Poly(ethylene glycol) has been used for stress (dehydration) treatment in seedlings of Galegae orientalis. It has been used for the preparation of aqueous two-phase system to study protein diffusion across the interface.
Other Notes
Fractional precipitation of proteins; Protoplast fusion; In virus purification; Electroblotting of proteins on agarose gel containing PEG and antibodies

Perguntas frequentes

What does UltraBio? mean?

UltraBio? indicates that the product has been processed and tested for biological and biochemical applications. Specifications may include endotoxin limits, microbial controls, sterility, low DNase/RNase/protease activity, and verified biological activity where relevant.

What does Ultra pure mean?

Ultra pure is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Ultra pure is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
