  • Publication number: 20200249244
    Abstract: The invention provides methods of detecting transthyretin (TTR) using a capture antibody and a reporter antibody. The capture antibody binds preferentially to misfolded TTR over native tetrameric form of TTR. The capture antibody binds to an epitope within amino acid residues 89-97 or TTR or to an epitope within amino acid residues 101-109 of TTR. 9D5 and 18C5 are examples of suitable capture antibodies. The methods can be used for diagnosing diseases or disorders associated with TTR accumulation or accumulation of TTR deposits (e.g., TTR amyloidosis) and for monitoring the efficacy of TTR therapies, among other applications.

    Abstract: A short-reach data link receiver includes an edge detector configured to generate a pulse on an edge of a data input, a first clock-data recovery path coupled to an output of the edge detector for recovering a clock and data from the output of the edge detector, a second clock-data recovery path coupled to the output of the edge detector for recovering the clock and data from the output of the edge detector, and a controller configured to alternate between the first and second clock-data recovery paths to recover the clock and data using one of the paths while calibrating the other path. The controller may swap the paths whenever calibration of one path is completed. That may include beginning calibration of the next path immediately after swapping of the paths. Alternatively, power consumption may be reduced by delaying calibration of the next path after swapping of the paths.
