(Universidade Federal de São Carlos, 2009-02-27)
The objective of this work was stabilize and immobilize β-galactosidase from activated agarose and chitosan supports. Initially, it was evaluated the buffer type, ionic strength and bivalent ions Mn2+ and Mg2+ on the ...
Estudo de condições operacionais na produção de penicilina G acilase por diferentes microrganismos
(Universidade Federal de São Carlos, 2006-12-20)
Penicillin G acylase (PGA) is an enzyme of major impact in human health for
catalyzing the deacilation of the penicillin G, to yield 6-aminopenicillanic acid (6-
APA), key intermediate in the semi-synthetic antibiotics ...
Quantificação de apoptose e necrose mediante corantes fluorescentes e análise de imagens, no cultivo de células de inseto: o caso da Drosophila melanogaster S2
(Universidade Federal de São Carlos, 2007-03-28)
In animal cell cultures there are two kinds of cell death: apoptosis
