Estimation of true values in radioimmunoassays.
We tested the accuracy of radioimmunoassays for two hormones, progesterone and estradiol, in relation to the use of two different antisera in each assay and to the degree of purification from plasma before the assay was done. Each analyte was assayed either in a diethyl ether extract, in a zone eluted from a Sephadex LH-20 chromatographic column, or in fractions of a chromatographic zone (from ...
متن کاملThe true and the experimental entropy values of vacancies
2014 The formation enthalpy and entropy of a Schottky defect in alkali halides depend on temperature due to anharmonic effects. Thus the experimental values of these parameters obtained at high temperatures do not coincide with the true ones. In the case of NaCl the experimental value of the formation enthalpy exceeds by 7 % the real formation enthalpy at absolute zero. The experimental value o...
متن کاملApparent and true metabolizable energy values of feedstuffs for ducks.
Two experiments were conducted, each with 24 White Pekin ducks, to determine the AME and TME content of five feedstuffs for ducks. In each experiment, fasting losses were obtained from six ducks and six ducks were used for each feedstuff. Each experiment lasted 102 h with an initial 48-h period and a 54-h excreta collection period. During the first 48-h period, all birds were tube-fed dextrose ...
متن کاملA New Precision–Fed Chick Assay for Determining True Metabolizable Energy Values of some Poultry Feed Ingredients for Broiler Chickens
Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...
متن کاملWhat are the true values of the bending modulus of simple lipid bilayers?
Values of the bending modulus KC are reviewed, and possible causes for the considerable differences are discussed. One possible cause is the use of glucose and sucrose in the classical micromechanical manipulation and shape analysis methods. New data, using the more recent low angle X-ray method, are presented that do not support an effect of glucose or sucrose on KC. Another possible cause is ...
