The present invention relates to a magnet plate for use in isolating a macromolecule from a mixture in a vessel, wherein the magnet plate has a reversible compression lock. The reversible compression lock engages the top plate and the base plate, wherein when in a locked position, the top plate is fixed and cannot move up and down, along the axis of the support or corner post and when in an unlocked position, the top plate is movable up and down along the axis of the support.

Provided are methods of evaluating a sample for presence of an analyte using a magnetic sensor and a dissociation reagent. In some embodiments the sample is magnetically labelled and bound to the magnetic sensor, after which a dissociation reagent is introduced to dissociate the magnetic label from the magnetic sensor. The magnetic sensor can be used to detect the magnetically labeled analyte before and after introduction of the dissociation reagent, thereby allowing for evaluating of the presence of the analyte. Exemplary samples include aqueous solutions containing proteins, DNA, RNA, and other biologically relevant analytes. In some cases the methods provide for an increase in the speed at which the magnetic sensor can evaluate samples. Also provided are apparatuses and kits for performing the methods.

A gas turbine engine can have a magnetic chip detector system with a first conductor member and a second conductor member both exposed to a lubricant flow path of the gas turbine engine, at least a first one of the conductor members including an electromagnet including a coil wrapped around a ferromagnetic core. As part of an engine shutdown procedure, an intrinsic magnetic field strength within the ferromagnetic core can be increased by circulating electrical current in the coil, and the electrical current circulation can then be interrupted for the magnetic field to remain active during engine shutdown.

The present application relates to detection units and methods for detecting one or more target analytes in a sample using a complex formed by a target and first and second probes, wherein the complex comprises an elongated region, a particle that is coupled to the first probe, and a solid support that is coupled to the second probe. Specific binding of a target analyte can be distinguished from non-specific binding of the particle by measuring the displacement of the particle.
