Abstract: The present invention relates to a method of determining an analyte in a sample, said method comprising (a) contacting said sample with (i) a binding compound binding to said analyte, said binding compound comprising a binding agent and a first partner of an affinity pair (first affinity partner); and (ii) a second partner of the affinity pair (second affinity partner) coupled to a solid surface, to an indicator, and/or to a second binding agent; and (b) determining said analyte based on complexes formed in step (a); wherein one of said first affinity partner and said second affinity partner is a polypeptide comprising the amino acid sequence of SEQ ID NO:1 or a sequence at least 50% identical thereto, and wherein the other of said first affinity partner and said second affinity partner is a polypeptide comprising the amino acid sequence of SEQ ID NO:2 or a sequence at least 50% identical thereto.

Abstract: An arrangement for floor gymnastics, particularly for the martial arts, has a floor element and a plurality of wall elements movable between an extended and a retracted position. The wall elements are located in the retracted position in accordion-like relationship with respect to each other. Fluid-operated drive means are provided for moving the wall elements between the retracted and extended positions. The movable wall portions include the portions which at least partially form a floor, a roof and longitudinal walls of the arrangement respectively. The wall elements in the extended position together bound an inner space which is free of supports. Some of the wall elements are hingedly connected with one another.
