A method for removing unbound labeling reagent from a composition comprising bound and unbound labeling reagent is described. Lilo-matrix conjugate capable of binding unbound labeling reagent is contacted with a biomolecule labeling reaction mixture and then the labeled biomolecule essentially free of unbound labeling reagent is removed.

A transmitter for recognising the positions of cylinders and/or camshafts in which, in order to pinpoint the position, a pseudo-random code is read into a register and the current position is found from the current content of the register. The code is displayed in an assessment arrangement in which the pulse sequences from one or two sensors are evaluated, whereby the sensors scan the suitably sur...

A preassembled air data sensor probe and air data transducer assembly has permanently connected flexible tubing coupling the air data transducer fittings and the sensor fittings. The flexible tubing permits the air data sensor and air data transducer to be installed into an air vehicle after having been preassembled and pretested for leaks at the factory. The permanently attached assembly avoids t...
