自身抗原微阵列正越来越多地被用于研究自身免疫。当比较微阵列表面、打印方法和探测条件时,观察到显著的变化。在这项研究中,使用>500用羽毛针印刷的自身抗原微阵列分析了24个表面和几个排列参数。一小部分载玻片,包括FAST®、PATH®和SuperEpoxy2,表现良好,同时保持了我们实验室以前证明的自身抗原微阵列的敏感性和特异性。通过优化我们自身抗原微阵列平台中的主要变量,可以识别血清样本中的细微差异,这将有助于揭示疾病的发病机制。
Autoantigen microarrays are being used increasingly to study autoimmunity. Significant variation has been observed when comparing microarray surfaces, printing methods, and probing conditions. In the present study, 24 surfaces and several arraying parameters were analyzed using >500 feature autoantigen microarrays printed with quill pins. A small subset of slides, including FAST®, PATH®, and SuperEpoxy2, performed well while maintaining the sensitivity and specificity of autoantigen microarrays previously demonstrated by our laboratory. By optimizing the major variables in our autoantigen microarray platform, subtle differences in serum samples can be identified that will shed light on disease pathogenesis.
