Abstract In this study seven adsorption azeotropes involving binary systems and zeolite-based adsorbents were systematically investigated. Pure component isotherms mixed-gas data taken from published literature except for the benzene–propene system on silicalite, which is newly presented in work using molecular simulations. Experimental adsorbed phase composition total amount of azeotropic comp...

The potency of various bee antigens including bee venom, several whole bee body extracts and fractions of bee venom was studied using the RAST inhibition method. As compared to whole bee body extract, bee venom was a much more potent inhibitor of both bee venom and whole body RAST, suggesting that venom has a greater capacity to bind specific bee IgE antibodies. Whole body extracts also varied ...

The allergenic potency of spore and mycelium extracts of Cladosporium was estimated by RAST, RAST inhibition and PCA tests. Spores contained a concentration of allergens higher than mycelia. Results of PCA tests suggested that spores contained specific allergens. However, in a comparative study of extracts from different species of Cladosporium animal and human models gave different estimates o...

Toluene diisocyanate was conjugated by two different methods to human serum albumin. These conjugates were used as antigens in the radio-allergo-sorbent-test (RAST) for detection of IgE antibodies in sera of isocyanate-sensitized persons. Chemical analyses have shown that conjugates containing 18-28 mol of isocyanate residues per mol protein were more potent antigens than those containing great...
