Abstract

The study was designed to isolate and identify serum IgG of native and imported chickens, after being immunized with Newcastle Disease Vaccine. The isolation method used was the DEAE-Cellulose ion exchange chromatography using 0.01 M Tris-HCl buffer, at pH 8.0, with linear gradient NaCl from 0.01 M to 0.30 M after salting out with anhydrous Na2SO4. Identification of IgG characteristics carried out using the Ouchterlony double immunodiffusion, immuno-electrophoresis and SDS-PAGE 8% methods. Serum fractionation of native and imported chickens using the DEAE-Cellulose chromatography, after salting out with anhydrous Na2So4 of 18,14 and 14% resulted in four peaks of protein fractions.

Abstract

The estimation of price sensitivity curves is usually based on historical data of the product. The estimates obtained, however, are potentially biased especially if the previous condition does not reflect the current market situation. alternativety, the estimation could be based on preference data. This paper introduces the use of Generalized Linear models to estimate the curve based on preference data.
