Abstract: A tool for removing burrs detects whether the depths of holes (81, 82, 83) made on a work (W) are prescribed depths or not. The tool (30) for removing burrs includes a tool case (31) and a piston (3) stored to move to and fro in the tool case. The piston has a spindle (12) arranged at its leading end. A judging section (61) judges whether the depth of the hole is normal or not, based on the results of the detection of whether the piston is retracted relatively to the tool case by a piston position detecting mechanism (56) and those of the detection of existence of the tool case by the tool case position detecting means (32).

Abstract: Antiserum which can recognize all subtypes of human leukocyte interferon is prepared from the blood of an animal immunized with partially purified human leukocyte interferon obtained from a culture of human leukocyte stimulated with Sendai virus.The antiserum is added to a column whereon concentrated culture broth of human leukocyte has been immobilized to adsorb impurities, the effluent is added to a column whereon partially purified human leukocyte interferon has been immobilized to adsorb anti-human leukocyte interferon antibody and then the antibody is eluted from the column.The antibody thus obtained recognizes all subtypes of human leukocyte interferon and can be separated by a chromatography to each monoclonal antibody which recognizes a single subtype.Employing these antibodies, the subtypes of human leukocyte interferon or their antibodies in a sample can be analized or assayed.
