摘要: A method of enzymatically measuring hydrogen peroxide by developing a color with use of 3-methyl-2-benzothiazolinoehydrazone as a coupler and in combination with an oxidative color developing reagent with peroxidase, and a reagent therefor is described. Catalase is added to the 3-methyl-2-benzothiazolinonehydrazone reagent as a stabilizer and the reaction is carried out in the presence of ethylenediaminetetraacetic acid or an analogue thereof. The color developing reaction may be carried out in neutral or weak alkali conditions. A reagent is described which comprises a buffer, 3-methyl-2-benzothiazolinohydrazone, and catalase.

摘要: A process for separating and recovering serum and plasma components from a whole blood sample including passing a whole blood sample through a separating filter formed of a blood cell separating layer composed mainly of fibers impregnated with a coating agent. A device includes a blood collector having a needle at one end and a blood suction means at the other end, and a separating filter including a blood cell separating layer, the filter being provided in the intermediate zone of the blood collector, whereby a whole blood sample sucked through the needle by depressurizing the blood suction means is passed through the separating filter.
