Quantitative Studies on the Precipitin Reaction Effect of Salts on the P~eaction*

In the studies on the precipitin reaction hitherto published from this laboratory (1) the salt concentration was held constant at 0.9 per cent of sodium chloride in order to permit observations on the effect of varying the proportions of antigen (or hapten) and antibody. In the present paper are reported data obtained during several years on the influence on the course of the precipitin reactio...

Nephelometric studies of the precipitin reaction: a model system for specific protein measurements.

Light-scattering studies have been carried out on an immunochemical system that serves as a model for specific protein determinations in biological samples. The influence of antigen/antibody ratio, salts, urea, pH, temperature, and excitation wavelength are presented. Of significance is the finding that ions, particularly F-, increase the rate of formation of and the light scattering from the a...

Quantitative Studies on the Neutralization Reaction between African Horse-sickness Virus and Antiserum

Catalytic Effect of Metal Species on Enhancement of CO2 Gasification Reactivity of Biomass Char

In the Boudouard reaction, where CO2 is reacted with carbon (char) to produce CO, very high temperatures are required to shift the equilibrium towards CO production. This endothermic reaction is inherently slow and catalytic species are effective to speed up the reaction rate at temperatures below 900 °C. In this study, the catalytic effect of some alkali (K, Na), alkaline earth (Ca) and transi...

Precipitation Reaction of SDS and Potassium Salts in Flocculation of a Micronized Megestrol Acetate Suspension

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...
