Polynucleotide phosphorylase from Synechocystis sp., Recombinant
Polynucleotide phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity. It is also involved in mRNA processing and degradation in bacteria, plants, and humans. Polynuclotide phosphorlyase in spinach chloroplasts acts as a exonuclease and a poly (a) polymerase. Applications: Polynucleotide phosphorylase has been used in a study to discover that a major function of pnpase is the synthesis of cdp. it has also been used in a study to investigate the enzyme responsible for rna 3?-tail synthesis in s. coelicolor. Group: Enzymes.

Polyolefin Elastomer
Polyolefin elastomer is a key functional modifier for a variety of polyolefin systems. This material has lower density, lower modulus, and a lower melting point vs. polyethylene or polypropylene. Due to these traits, POE is often used as an impact or softness modifier. Additionally, POE can be used in flexible products such as film. It has the ability to modify heat seal initiation temperatures (HSIT) as well as promote "easy-peel" properties.

Polyoxyethylene Alkyl Ethers
Polyoxyethylene alkyl ethers vary considerably in their physical appearance from liquids, to pastes, to solid waxy substances. They are colorless, white, cream-colored or pale yellow materials with a slight odor. CAS No. 9004-95-9. Product ID: PE-0498. Category: Sweetening agent. Product Keywords: Pharmaceutical Excipients; Excipients for Solid Dosage Form; Polyoxyethylene Alkyl Ethers; Sweeteners Excipients; Sweetening agent; /; 9004-95-9; 9004-95-9. UNII: NA. Chemical Name: Polyethylene glycol monocetyl ether; Polyethylene glycol monolauryl ether; Polyethylene glycol monooleyl ether; Polyethylene glycol monostearyl ether. Stability and Storage Conditions: Polyoxyethylene alkyl ethers are chemically stable in strongly acidic or alkaline conditions. The presence of strong electrolytes may, however, adversely affect the physical stability of emulsions containing polyoxyethylene alkyl ethers.On storage, polyoxyethylene alkyl ethers can undergo autoxidation, resulting in the formation of peroxides with an increase in acidity. Many commercially available grades are thus supplied with added antioxidants. Typically, a mixture of 0.01% butylated hydroxyanisole and 0.005% citric acid is used for this purpose. Polyoxyethylene alkyl ethers should be stored in an airtight container, in a cool, dry place. Source and Preparation: Polyoxyethylene alkyl ethers are prepared by the condensation of linear fatty alcohols
