Polyethylene glycol (PEG) has many varieties, including PEG400, PEDR0471, PEG4000, PEG6000, PEG8000, etc. The PEG series products are non-toxic, non irritating, slightly bitter in taste, and have good water solubility. They also have good compatibility with many organic components, and have excellent lubricity, moisturizing, dispersibility, adhesives, anti-static agents, and softeners. They are widely used in industries such as cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, painting, electroplating, pesticides, metal processing, and food processing. The properties vary depending on the relative molecular weight. From colorless and odorless viscous liquids to waxy solids, those with a molecular weight of 200-600 are liquids at room temperature, while those with a molecular weight above 600 gradually become semi-solid. The properties also differ with the average molecular weight. From colorless and odorless viscous liquids to waxy solids, as the molecular weight increases, their hygroscopicity decreases accordingly; Among them, PEG4000 and PEG6000 are commonly used to promote cell fusion or protoplast fusion and help organisms (such as yeast) uptake DNA during transformation.

PEG8000 Solution(50%, Sterilized) is mainly composed of PEG8000 and phosphate, and has undergone strict aseptic treatment. Its principle of action is to change the membrane structure of various types of cells, causing the lipid molecules on the plasma membrane at the contact point of two cells to disperse and recombine. The interface between two cells is located at the bilayer plasma membrane, and under the mutual affinity and surface tension of each other, cells fuse. PEG8000 Solution(50%, Sterilized) can be used as a fusion agent to obtain hybridoma cells for producing monoclonal antibodies. This reagent is only used in the field of scientific research and is not suitable for clinical diagnosis or other purposes.
