A sensitive blotting system for detection of α-fetoprotein variants with monoclonal and polyclonal antibodies
(Elsevier, 1988-08-19)Human α-fetoprotein (AFP) variants from cord sera were separated by isoelectric focusing in agarose gels under native conditions, transferred to nitrocellulose paper and detected with polyclonal and monoclonal antibodies ... -
Brucella abortus transits through the autophagic pathway and replicates in the endoplasmic reticulum of nonprofessional phagocytes
(American Society for Microbiology, 1988-09-01)Brucella abortus is an intracellular pathogen that replicates within a membrane-bounded compartment. In this study, we have examined the intracellular pathway of the virulent B. abortus strain 2308 (S2308) and the attenuated ... -
A method to obtain rapid zoosporogenesis of Pythium insidiosum
(Kluwer Academic Publishers, 1988-10)Nine strains of Pythium insidiosum the etiologic agent of pythiosis, were inoculated on 2% water agar plus grass blades and then incubated one day at 25°C, 35°C and 37°C. Sporangium and secondary biflagellate-type zoosporas ... -
