摘要： A carbonate ion selective membrane comprises (a) a polymeric inert support material; (b) a plasticizer effective to solubilize the support material; (c) a quaternary ammonium ion; (d) an ionophore which is preferentially reactive with carbonate ions; and (e) a hydrophobic molecule effective to exclude ions other than carbonate ions. The hydrophobic molecule in the membrane assists in the «binding» of the organic constituents to the matrix, and it repels charged species, i.e. anions and cations, from the solution phase, thereby improving selectivity to the carbonate species which enters the membrane via selective complexation with the ionophore. The quaternary ammonium ion is preferably a C 7 to C 9 quaternary ammonium ion. In this case, the plasticizer is selected to be one effective to maximize the binding of carbonate ions with the C 7 to C 9 quaternary ammonium ions. The invention further provides a carbonate ion selective electrode comprising an internal reference element in electrochemical contact with the membrane described above.

摘要： @ A specific binding assay composition for determining a ligand in a sample, comprises (a) a binding partner for the ligand; (b) a detection system which has at least two components; (c) a selectively accessible vesicle having a surface-incorporated ligand or ligand analog and a first component of the detection system therein; (d) a substance which modifies vesicle accessibility in response to binding of surface-associated ligand or ligand analog and binding partner; and (e) at least one additional component of the detection system which is reactive with the first component to produce a detectable response which is reduced by association of the binding partner and vescile modifying substance with the variably accessible vesicle. A decrease in signal is measured upon reaction as compared to the signal of unreacted vesicles.

摘要： New and improved, liquid level adjusting and filtering device is provided, and is operable upon insertion into a container to automatically adjust the level of a liquid as contained in the container to a predetermined, precisely repeatable location, and to filterthethusly level-adjusted liquid. The device is particularly adapted for use in conjunction with test tube-like devices, in the nature of those marketed under the trademark "Vacutainer" by the Becton Dickinson Company of East Rutherford, New Jersey, containing whole blood samples which have been separated as by centrifugation into respective blood cell, buffy and blood serum layers; and is operable in that context to present blood serum samples to automated sample analysis systems at the same predetermined and precisely repeatable location relative to the aspirating probe means of such systems.
