摘要:
The semi-insulating aluminum nitride sintered body of this invention is composed of aluminum nitride particles, electroconductive fine particles having a volume inherent resistivity value of not larger than 10.sup.2 .OMEGA..multidot.cm which are dispersed among the aluminum nitride particles and an intergranular phase formed from an oxide containing at least one element selected from the group consisting of Ti, Ce, Ni, Ta, Y, Er and Yb, or from Si. This sintered body has a volume inherent resistivity value of 10.sup.4 to 10.sup.11 .OMEGA..multidot.cm, and is very useful, for example, as a member for removing static electricity, or a dielectric layer of an electrostatic chuck. Since dispersions of volume inherent resistivity values are very small, a material having a volume inherent resistivity value within a certain range can be produced with good reproducibility. Accordingly, the yield is high, and the productivity is very good.
摘要:
A monoclonal antibody which specifically reacts with D-monomer produced by digesting human fibrinogen with granulocyte elastase and D-domain containing digestion products produced by digesting human stabilized fibrin with granulocyte elastase, but does not react with fibrinogen, or fragment X, Y or E produced by digesting fibrinogen with granulocyte elastase is disclosed. The D-dimer or DD/E complex produced by digestion with granulocyte elastase in a sample from a living body can be analyzed without being interferred with fibrinogen, digestion products of fibrinogen with plasmin, or digestion products of stabilized fibrin with plasmin, using the monoclonal antibody.
摘要:
A monoclonal antibody that reacts with a human soluble fibrin but not with a human fibrinogen; a hybridoma that secretes the above antibody; and a method of assaying a human soluble fibrin with the above antibody. It is possible to determine the amount of soluble fibrin in the plasma of a patient specifically, readily and rapidly by agglutination and EIA without being affected by plasma fibrinogen, plasmin-degradation product of fibrinogen, fibrin fragment, and plasmin-degradation product of stabilized fibrin even without pretreating the plasma sample.
