Abstract

A method for measuring an oligonucleotide which is simpler and more sensitive and has excellent specificity and quantitative capability compared to the conventional measurement method is provided. Moreover, a method for measuring an oligonucleotide having excellent specificity which can distinguish the intact target oligonucleotide (unchanged form) and a metabolite thereof and detect the unchanged form only is provided. In a hybridization method using a capture probe and an assist probe, by inserting a spacer between a solid phase and a nucleic acid probe contained in the capture probe, it becomes possible not only to detect the target oligonucleotide in a sample but also to distinguish from a metabolite of a nucleic acid drug.

Abstract

A heat transfer sheet includes: at least one of a carbon fiber and a boron nitride flake; an inorganic filler, and a binder resin. The at least one of the carbon fiber and the boron nitride flake is oriented in a thickness direction of the heat transfer sheet. When the heat transfer sheet is in a sealed state under a reduced pressure of 150 to 300 torr for one minute or more and removed from the sealed state, a tack force of the heat transfer sheet satisfies condition 1: the tack force of the heat transfer sheet is 100 gf or more when a probe having a diameter of 5.1 mm presses in the heat transfer sheet at a force of 200 gf at 2 mm/sec and pulls it off at 10 mm/sec.

Abstract

The present invention provides an immunological detection method for trimeric type I collagen N-terminal propeptide in a biological sample, which uses a first antibody that binds to a first specific portion of a pro-al chain in the trimeric type I collagen N-terminal propeptide and a second antibody that binds to a second specific portion of a pro-al chain in the trimeric type I collagen N-terminal propeptide. The immunological detection method is easy to handle and can specifically (selectively) measure the trimer in biological samples containing the trimer and monomer of the α-chain of PINP.
