A turbidimetric method for the assay of hyaluronidase.
A variety of methods have been devised for the assay of the enzyme hyaluronidase. These may be divided into four types: (a) measurement of the “spreading effect” in the skin of rabbits and guinea pigs (1, 2), (b) reduction of viscosity (3,4), (c) prevention of mucin clot formation (5), and (d) chemical measurement of total reducing substances, N-acetylglucosamine, or glucuronic acid liberated o...
متن کاملTurbidimetric method for the assay of antiviral antibodies.
A rapid, simple assay method has been developed for antiviral antibodies. The technique has been applied to antisera, immune gamma-globulins, and immunospecifically purified antibody for two strains of influenza virus, Asian 305 and PR8, and to antisera to tobacco mosaic virus. Turbidity changes due to the specific interaction of a virus with its antibody were measured by the increase in optica...
متن کاملRapid Micro Method for the Turbidimetric Determination of Serum Protein *
The significance of altered serum proteins in disease has long been recognized, but most of the current modes of analysis are either too complicated for routine use or yield unreliable data which are difficult to interpret. In a study of serum proteins for diagnostic purposes, it is essential to have a simple, inexpensive, but accurate procedure for complete protein analysis that will require o...
متن کاملinvestigating 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...
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...
