(Maik Nauka/Interperiodıca/Springer, 2006)Human serum paraoxonase (hPON 1) was separately purified by ammonium sulfate precipitation and hydrophobic interaction chromatography The in vitro effects of commonly used antibiotics, namely clarithromycin and chloramphenicol, ... -
Purification and characterization of Ocimum basilicum L. polyphenol oxidase
(Amer Chemical Soc,, 2005)A partial characterization of polyphenol oxidase (PPO) activity in Ocimum basilicum L. is described. PPO in O. basilicum L. was extracted and purified through (NH4)(2)SO4 precipitation, dialysis, and a Sepharose ... -
Purification and characterization of an intracellular beta-glucosidase from the methylotrophic yeast Pichia pastoris
(Maik Nauka/Interperiodica, 2005)Pichia pastoris beta-glucosidase was purified to apparent homogeneity by salting out with ammonium sulfate, gel filtration, and ion-exchange chromatography with Q-Sepharose and CM-Sepharose. The enzyme is a tetramer (275 ... -
Investigations of genetic variation between olive (Olea europaea L.) cultivars using arbitrarily primed polymerase chain reaction (AP-PCR)
(Verlag Z Naturforsch, 2003)Characterization and selection of olive clones for the production of olive oil is essential in Turkey because of its profitable exploitation. AP-PCR (Arbitrarily-Primed PCR) is a technique that can distinguish the genetic ... -
In vitro antimicrobial activity and chemical composition of some Satureja essential oils
