Poly-3-hydroxybutyrate Synthesis Protocol

Poly-3-hydroxybutyrate (the weight average molecular weight M_w 840 kDa; polydispersity 2.70) was synthesized in Siberian Federal University according to previously described technology [31 (link)]. The following reagents were used: N,N-dimethylformamide for synthesis from Roth, Germany; reagent grade 1,4-dioxane, ACS grade isopropyl alcohol and purified chloroform from ECOS-1, Russia; 1,4-diaminobutane (98+% purity) from Alfa Aesar, Kandel, Germany; ethylene-1,2-diamine for synthesis and monoethanolamine for synthesis from Merck, Darmstadt, Germany.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
