Abstract: A method for determining ligands in a sample is disclosed. The method involves mixing with the sample in which the ligand is to be determined a tracer having the formula of Fig. 1 of the attached drawings or a biologically acceptable salt of such a tracer, a monoclonal antibody, and glycerol added as a part of a solution of the monoclonal antibody in which the glycerol is present in an amount sufficient to increase the stability of the monoclonal antibody in the solution, and then determining the amount of tracer bound to the antibody by fluorescence polarization techniques as a measure of the amount of ligand in the sample. In Fig. 1 of the drawings R is a ligand or analog thereof having at least one common epitope with a ligand to be determined so that the ligand to be determined and the ligand or analog thereof of the tracer are both specifically recognizable by a given antibody, and N is an integer from one to ten. The monoclonal antibody used is one which is capable of specifically recognizing both the ligand to be determined and the tracer. Glycerol is used in the monoclonal antibody solution in an amount, usually from about 5 percent to about 20 percent, sufficient to increase the stability of the monoclonal antibody. The optimum glycerol concentration has been found to be about 10%.

Abstract: A power factor correction circuit employs a metal oxide varistor (24) in series with a filter capacitor (C1). The varistor (24) provides a low-impedance path for pre-charging the filter capacitor (C1), thus enabling the avoidance of high inrush current to circuit devices, while the filter capacitor (C1) energizes the circuit when the capacitor voltage exceeds the AC source (10) voltage. The circuit is insensitive to normal line transients. One application is for use in a gas discharge lamp (14) ballast.

Abstract: An FM detection circuit utilizes a first multiplier (16) and phase shift circuit (18) to demodulate an FM signal. The output signal also contains harmonic distortion as a result of the demodulation process. A gain control circuit (30, 32) is included to provide a first gain control signal to the first multiplier which adjusts the magnitude of the output signal of the FM detection circuit in such a manner as to substantially eliminate the harmonic distortion. The gain control circuit uses a second multiplier (22) to generate an output signal proportional to the square of the output signal of the phase shift circuit which is then compared to a constant current to produce an error signal proportional to the harmonic distortion. The error signal controls the magnitude of the first gain control signal such that the output signal of the FM detection circuit is proportional to the deviation of the FM signal from its center frequency.
