Abstract: Disclosed is a cell classification method, to be executed by an analyzer, for classifying cells contained in a specimen, including: preparing a first measurement sample by treating a specimen under a first preparation condition; obtaining a first signal from the prepared first measurement sample; classifying, by using the first signal, cells contained in the first measurement sample; preparing a second measurement sample by treating the specimen under a second preparation condition different from the first preparation condition; obtaining a second signal from the prepared second measurement sample; classifying, by using the second signal, cells contained in the second measurement sample; and comparing a result of the cell classification performed by using the first signal and a result of the cell classification performed by using the second signal, with each other, and outputting an analysis result including a number of cells on the basis of a result of the comparison.

Abstract: Provided are blades 22R, 22C, 22L rotatably driven about rotational axes XL, XC, XR to be able to cut grass on the ground surface, a housing covering the blades 22R, 22C, 22L and having a lower face thereof opened, a water feeding section provided outside the housing, a water discharging section 54 provided inside the housing for discharging cleaning water fed to the water feeding section, and a water feeding pipe 55 connected to/between the water feeding section and the water discharging section 54. The water discharging section 54 discharges water toward an inner wall face of the housing.

Abstract: A method for preparing a PRP conjugate having high storage stability and a method for producing a Hib conjugate vaccine are provided. A method for preparing PRP conjugate in accordance with the embodiments of the present invention is characterized by that the release of PRPs after preparing the PRP conjugate is suppressed by using PRP with a lowered molecular weight than native PRP for a coupling reaction between PRP and a carrier protein. Also, a Hib conjugate vaccine comprising as an antigen the PRP conjugate prepared by said method has excellent storage stability and maintain sufficient immunogenicity.
