在多分叶核粒细胞抗原中(NA、NB、ND、NE…)NA抗原是最常见的。它是一种糖蛋白,位于中性粒细胞PCRⅢb受体上,表现为NA1和NA2。其多态性与氨基酸成分有关。最初用于NA抗原分析的技术主要有微量凝集试验、粒细胞毒试验,而后是免疫荧光试验和抗原捕捉试验(MAIGA)。直到近年更为有效的技术出现,如流式细胞仪法和聚合酶链反应(PCR),这些方法可以确定中性粒细胞特异性抗原的表现型和基因型。研究表 NA antigens are the most common among multiple leaf nuclear granulocyte antigens (NA, NB, ND, NE ...). It is a glycoprotein located on the neutrophil PCR IIIb receptor and appears as NA1 and NA2. Its polymorphism and amino acid composition. Initially used for NA antigen analysis techniques are microagglutination test, cytotoxicity test, followed by immunofluorescence assay and antigen capture test (MAIGA). Until recently, more effective techniques such as flow cytometry and polymerase chain reaction (PCR) have emerged that can determine the phenotype and genotype of neutrophil-specific antigens.
