Laboratory experiments on the evaluation of infectivity of Beauveria bassiana (Bals.) Vuill. to tobacco caterpillar Spodoptera litura Fab. as influenced by two okra varieties. Infectivity of B. bassiana at three concentrations viz. 0.1, 1.0 and 3.0 per cent was evaluated by contaminated food bioassay method. In comparison, topical bioassay method was also made. Statistically significant variati...
The human growth hormone (hGH) and human prolactin (hPRL) were iodinated with 125I using the lactoperoxidase method and purified by gel filtration on a Sephadex G-100 column and by ion exchange chromatography on a diethyl-aminoethyl (DEAE) cellulose column. Aliquots of the peak fraction on the Sephadex G-100 column and each fraction on the DEAE cellulose column were tested by radioimmunoassay (...
Lactobacillus arabinosus 17-5 has been widely used as an assay organism for nicotinic acid (NA) since the development of the method by Snell and Wright (1). Although it has been realized that other substances present in tissue extracts may interfere with the bioassay, the nature of such substances has not been elucidated. During an investigation of tryptophan metabolism in the pea plant, we stu...
In this paper, we present the design of four different circular bioassay platforms, which are suitable for homogeneous microwave heating, using theoretical calculations (i.e., COMSOL™ multiphysics software). Circular bioassay platforms are constructed from poly(methyl methacrylate) (PMMA) for optical transparency between 400-800 nm, has multiple sample capacity (12, 16, 19 and 21 wells) and mod...
