Description

General description

Pentaerythritol propoxylate (5/4 PO/OH) is a pentaerythriol based branched polymer that can be used as a crystallization agent to generate ordered, high resolution diffraction quality crystals.

Application

Pentaerythritol propoxylate may be used as a precipitant in reservoir solution for the crystallization of Phosphate Transporter(PiPT) and Aggregation Suppressing Protein A(AgsA). It may also acts as a reservoir solution for Phytosulfokine (PSK)- receptor PSKR- and somatic embryogenesis receptor-like kinases (SERKs) complex.
