Precursor cells from different lineages express different subsets of surface molecules , many of which are now difined by cluster of differentiation ( cd ) antigens . cd antigens associated with the plasma membranes of leukocytes may be molecules involved in a variety of functions 蛋白芯片可以将蛋白质以阵列的方式固定在经化学或生物酶处理的表面上,也可将受体蛋白、抗体等固定在表面上,未知分子可以利用与芯片不同位点亲和力来分析。
The who classification states that acute lymphocytic leukemia ( all ) should be classified by the pattern of reactivity of cell to a panel of lineage - associated antibodies and , where possible , genetic abnormalities . the expression of cd antigens on leukocytes is currently determined by flow cytimertry , which is expensive and labor - intensive , requiring 5 - 20ul quantities of fluores - cently labeled antibodies and allowing concurrent analysis for a limited number of cd antigens , usually three to four . from clinical point of view , an efficient method is required for analysis of a large number of samples in a single experiment 我们设计了一种新型的细胞芯片,其原理是充分利用玻片的硬度高,透明性好的特点,应用细胞膜表面不同的抗原物质,与包被在玻片上的不同抗体发生特异性结合,通过一次实验可以将被测细胞悬液中不同膜表型的细胞分离、固定在同一张玻片的不同特定区域,保持了细胞的完整性及活性,又可通过简单的操作一次将多细胞悬液进行免疫分群。
