A futon (Japanese quilt) was beaten to disperse mite allergens into the air in a closed room, and the airborne allergens were collected both by Andersen air sampler for particle size analysis and by slit air sampler for kinetic analysis of the clearing of the allergens from the air. After extraction of the allergens from the agar plates in the samplers, two kinds of major mite allergens (Der I and Der II) were immunochemically quantitated. We found that the aerodynamic diameters of both allergens were mainly above 5.5 microns, and that airborne allergen levels decreased to about 10% of the starting level in 30 minutes, indicating the rapidity of the falling of both allergens.
在一个封闭房间里，拍打蒲团（日式棉被）以将螨虫过敏原散布到空气中，然后通过用于粒径分析的安德森空气采样器和用于分析空气中过敏原清除动力学的狭缝空气采样器收集空气中的过敏原。从采样器中的琼脂平板上提取过敏原后，对两种主要的螨虫过敏原（Der I和Der II）进行免疫化学定量分析。我们发现，两种过敏原的空气动力学直径主要在5.5微米以上，并且空气中的过敏原水平在30分钟内降至初始水平的约10%，这表明两种过敏原沉降速度很快。
