Abstract
Provided are a method for preparing reticulocyte simulating particles and platelet simulating particles, and a reference control. The method for preparing the reticulocyte simulating particles comprises: staining mammalian anucleated red blood cells having a volume of 60-120 fL with a protein fluorescent dye activated by N-hydroxysuccinimide, and fixing the anucleated red blood cells to prepare the reticulocyte simulating particles. The platelet simulating particles are prepared from mammalian anucleated red blood cells having a volume of 2-25 fL, and the steps of preparing the platelet simulating particles are the same as that for the reticulocyte simulating particles. The preparation method comprises: using an protein fluorescent dye activated by N-hydroxysuccinimide to stain mammalian anucleated red blood cells having different volumes, so as to respectively obtain reticulocyte simulating particles and platelet simulating particles. The fluorescence and volume direction thereof in the scatter diagram are similar to the scatter diagram distribution of reticulocytes, reticulated platelets and platelets in fresh blood. The prepared simulating particles have good stability and do not interfere with the counting and differentiation of other cell particles.
