Peg has many uses in molecular cloning

Polypropylene glycol PPG is a kind of polymer with propylene oxide or propylene oxide and ethylene oxide as starting agent. Polypropylene glycol PPG is a colorless to light yellow viscous liquid. Polypropylene glycol PPG is non-volatile and non corrosive. It is generally called polypropylene glycol PPG. This product is widely used in polyurethane. Polypropylene glycol PPG can be used as starting agent and polypropylene glycol PPG can be used as catalyst With the reaction of propylene oxide and propylene oxide, PPG can be produced into PPG.

Polyethylene glycol PEG can induce the aggregation of macromolecules in aqueous solution. Polyethylene glycol PEG has many uses in molecular cloning. When polyethylene glycol PEG is hybridized, DNA molecule is connected at the flat end and T4 polynucleokinase is used for DNA end labeling, polyethylene glycol PEG is used as dispersant and emulsifier in the industrial production of pesticide and pigment, increasing the binding efficiency of complementary nucleic acid chain, and polyethylene glycol PEG molecular energy By changing the structure of biomembrane of all kinds of cells, the lipid molecules in the plasma membrane at the contact point of the two cells will be evacuated and recombined. Because of the mutual affinity and surface tension of the bimolecular plasma membrane at the interface of the two cells, polyethylene glycol PEG will fuse the cells, thus forming hybrid cells. Some special properties can be obtained by cultivating the hybrid cells with polyethylene glycol PEG Hybrid plants.

Antistatic agents are very soluble in fuel oil:

Defoamer has lower surface tension and higher surface activity. It can inhibit or eliminate foam in liquid. Defoamer can prevent and eliminate harmful bubbles produced during food processing and make operation smooth. Defoamer usually uses oil with little volatility and strong diffusing power, or water-soluble surfactant. Defoamer is the most widely used defoamer is organosilicon resin. Organochlorosilane monomer is prepared by catalytic reaction of organosilicon and organochloride. It is separated by distillation to remove by-products, and then obtained by hydrolysis and condensation. Defoamer is used in monosodium glutamate fermentation, wine, soy sauce, sugar, dairy products, jam and other manufacturing, enzyme and starch extraction and processing. Defoamer can eliminate various factors The foams formed can be selected according to the specific conditions and requirements of each process.

Antistatic agent is a kind of organic polymer condensed by a variety of high molecular organic compounds and dissolved in aromatic solvent. Antistatic agent is very easy to dissolve in fuel oil. During the hydrogenation treatment of antistatic agent oil, the natural conductivity is removed and its conductivity is sharply reduced. Adding antistatic agent directly into the fuel oil can rapidly improve the conductivity of the fuel oil. The antistatic agent enables the charge to be released to the ground through grounding. When the diesel oil needs to be replaced with gasoline, or a certain amount of antistatic agent is added during loading and unloading of the fuel oil, the conductivity of the fuel oil will be improved, so as to avoid fire and explosion caused by the oil. The addition amount of antistatic agent is small and the operation is simple, Low cost, obvious effect, can effectively improve the conductivity of oil, and will not affect the properties of oil.
