This invention relates to a method of separation of the leucocyte populations of human blood, and more particularly to a rapid one-step density separation method of mononuclear leucocytes, polymorphonuclear leucocytes and erythrocytes (red blood cells) using a separating medium consisting of a single aqueous solution of (i) an erythrocyte aggregating or clumping agent and (ii) a compound which is highly soluble in water and gives a solution of relatively high density and relatively low viscosity and osmolarity.
本发明涉及一种分离人体血液中白细胞群的方法,更具体地说,涉及一种单核白细胞、多形核白细胞和红细胞(红血球)的一步快速密度分离法,使用的分离介质包括(i)一种红细胞聚集剂或凝集剂和(ii)一种化合物的单一
水溶液,该化合物极易溶于
水,可产生密度相对较高、粘度和渗透压相对较低的溶液。
