T-DNA transfer to maize cells: histochemical investigation of beta-glucuronidase activity in maize tissues.
Agrobacterium tumefaciens is routinely used to engineer desirable genes into dicotyledonous plants. However, the economically important graminaceous plant maize is refractory to tumor induction by inoculation with virulent strains of A. tumefaciens. Currently, the only clearcut evidence for transferred DNA (T-DNA) transport from Agrobacterium to maize comes from agroinfection. To study T-DNA tr...
متن کاملColorimetric enumeration of Escherichia coli based on beta-glucuronidase activity.
A medium containing a chromogenic substrate was developed for the enumeration of Escherichia coli on the basis of beta-glucuronidase activity. In this medium there was an inverse linear relationship between the log initial E. coli concentration and the time taken for the color to reach a threshold optical density of 0.05. This relationship applied even when the E. coli population contained 5% b...
متن کاملA note on the determination of serum beta-glucuronidase activity.
A modification of the method of Fishman, Springer, and Brunetti (1948) for determining serum beta-glucuronidase activity is described. Normal values are presented and some of the factors which might influence the serum enzyme determination have been investigated.
متن کاملSerum beta-glucuronidase activity in a population of ex-coalminers.
BACKGROUND The aim of this study was to investigate whether BGD activity is of additional value in the assessment of pulmonary inflammation caused by coal dust exposure. DESIGN AND METHODS Ex-coalminers were included in this study. Forty-eight healthy male subjects, without a relevant medical history, were used as controls. RESULTS In ex-coalminers serum BGD activity was higher compared to ...
متن کاملApplication of an improved glucuronidase assay method to the study of human blood beta-glucuronidase.
Previous conditions in which phenolphthalein glucuronide was employed as substrate (1) have proved unsatisfactory for the determination of glucuronidase in plasma, serum, and laked blood cells. Thus, low glucuronidase activities such as frequently occur in plasma could not be accurately measured or even approximated, owing to a combination of circumstances; i.e., too short an incubation period ...
