A plate assay method for the detection of fungal polygalacturonase secretion

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Large-plate method for the assay of neomycin in serum.

A large-plate method employing radial diffusion from small paper discs for assaying serum levels of neomycin is described. More than 120 discs placed on a loading plate and loaded with 20 muliters of sample could all be brought into contact with the agar plate at one time. The requirement for elaborate statistical design to compensate for time-dependent bias was thus eliminated. The dose-respon...

Assessment of a rapid immunochromatographic assay for the detection of avian influenza viruses

Rapid spreading of the low pathogenic avian influenza virus (AIV) caused by the H9N2 subtype and the highly pathogenic AIV caused by H5N1 have caused serious economic losses in the poultry industries of Asia. Therefore, the early detection of AIVs is crucial for the control of the disease. In the present study, the applicability of a rapid immunochromatographic (RIC) assay, which specifically d...

A Peroxidase-linked Spectrophotometric Assay for the Detection of Monoamine Oxidase Inhibitors

To develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the HPLC method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(Trifluoromethyl) benzylamine (11) was proved to be an exc...
