A kit for the determination of the ability of a peripheral blood mononuclear cell to bind to a polysaccharide herein provided comprises a detection reagent comprising a fluorescence-labeled immunostimulant polysaccharide; and a reference reagent comprising a fluorescence-labeled material of a polysaccharide different from that used in the fluorescence-labeled immunostimulant polysaccharide, and/or an immunostimulant polysaccharide which is not labeled with any fluorescent material and whose polysaccharide moiety is identical to that included in the fluorescence-labeled immunostimulant polysaccharide. The use of this kit would permit the estimation of the polysaccharide-binding ability of a peripheral blood mononuclear cell in a higher precision of estimation.

Adapter-type optical isolator 1 has split sleeve 7 within housings A and B. Polarization-independent optical isolator is of such a structure that optical isolator device 3 which is an integral assembly of a Faraday rotator and a birefringent crystal element is provided within hollow cylindrical magnet 4. Beam changing elements 5a and 5b are in the form of optical coupling lenses or core-flared fibers. Adapter-type optical isolator 1 has the polarization-independent optical isolator and beam changing elements 5a and 5b fitted snugly within the bore of split sleeve 7 in the central area in such a way that the polarization-independent optical isolator is held between beam changing elements 5a and 5b. An optical connector using the adapter-type optical isolator 1 is simple in construction, permits simple assembly and adjustments, is small, allows for easy optical adjustments on individual optical parts, features high operational stability and can be incorporated into a wide variety of measuring instruments and communication equipment.

摘要:
The ability of a polysaccharide to act as an immunostimulant may be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a reference reagent, which contains a fluorescence-labeled version of a different polysaccharide. The ability of a polysaccharide to act as an immunostimulant may also be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a different type of reference reagent, which contains both the same fluorescence-labeled version of the polysaccharide and an unlabelled version of the same polysaccharide.
摘要:
An optical coupler having a tapered fused region produced by locally heating the periphery of a plurality of aligned optical fibers, each having a core and a cladding, so that the optical fibers fuse together at the heated part, and then drawing the resulting fused region by pulling. The length of the fused region is not longer than 10 mm. The tapered fused region may be provided in such a manner that a plurality of optical fibers are disposed to intersect each other at a predetermined angle, and the intersecting portions are locally heated so as to fuse together and then subjected to pulling. The tapered fused region may be provided at each of two or more positions. Also disclosed is an optical coupler wherein at least one of a plurality of optical fibers each having a core and a cladding is previously heat-treated at a high temperature to enlarge the core in a portion thereof, and the enlarged-core portion of this optical fiber is fused to the other optical fibers and then subjected to pulling, thereby forming a tapered fused region.
