Biochemical, Pharmacological and Structural Characterization of Two PLA2 Isoforms Cdr-12 and Cdr-13 from Crotalus durissus ruruima Snake Venom
Autor: Sergio Marangoni, Frey Francisco Romero-Vargas, José C. Novello, Paulo A. Baldasso, Flavia Vischi Winck, Luis Alberto Ponce-Soto
Publikováno v: The Protein Journal. 26:39-49
Cdr-12 and Cdr-13 isoforms of PLA2, a D49 protein, were purified from Crotalus durissus ruruima venom after one chromatographic step, reverse phase HPLC on micro-Bondapack C-18. The molecular mass by SDS-PAGE of Cdr-12 and Cdr-13 isoforms of PLA2 was

Enhanced architecture of lipid-carbon nanotubes as langmuir-blodgett films to investigate the enzyme activity of phospholipases from snake venom
Autor: Vera L. B. Tiburcio, Sergio Marangoni, José R. Siqueira, Luciano Caseli, Frey Francisco Romero Vargas
Publikováno v: The journal of physical chemistry. B. 116(45)
The immobilization of biomolecules in films with a controlled architecture permits the access of information on the molecular interactions, not only between film components, but also between the film and substances in the external environment. In thi
