Abstract: A protein produced by an expression system that includes a nucleic acid sequence that encodes an MHC class I heavy chain. The MHC class I heavy chain comprises an alpha-1 helix and an alpha-2 helix. The nucleic acid sequence has a disulfide bridge formed between the alpha-1 helix and the alpha-2 helix in the MHC class I heavy chain. Amino acid 139 is substituted by a cysteine so as to provide Cys-139. Amino acid 84 is substituted by the cysteine so as to provide Cys-84 or amino acid 85 is substituted by the cysteine so as to provide Cys-85. The disulfide bridge is formed between the alpha-1 helix and the alpha-2 helix in the MHC class I heavy chain between Cys-139 and Cys-84 or between Cys-139 and Cys-85. The protein comprises an anchor element selected from a natural biotinylation sequence, a polyhistidine sequence, or a polyarginine sequence.

Abstract: A method and a corresponding device determines the speed of a moving entity carrying at least two antennas for receiving a transmission signal the antennas being displaced at a predetermined distance. In order to provide a more simple and accurate method which can be used with different transmission signals the method includes the steps of: receiving a transmission signal by the antennas, determining signal characteristics from the transmission signal as received by the determining a time offset between the reception of the transmission signal at the antennas by comparing the signal characteristics determined for the antennas, and determining the speed of the moving entity from the determined time offset, the distance of the antennas and the direction of movement of the moving entity relative to the arrangement of the antennas.
