研究者应该格外注意以下步骤：为更好的解码精度，有必要验证微球均匀地悬浮在所有孵育和微球编码过程中的洗涤步骤。此外，经编码的微球需要在整个实验中，以避光。下列正确的编码和储存程序中，我们发现，总体解码准确率为99％以上。该编码微球应保存在4℃保存，避免冷冻和避光。在适当的储存条件下，编码微球是稳定超过六个月。在编码和修改步骤，需要格外小心，以?...

由于报道由Mark Schena并在90年代中期的同事第一芯片，这个强大的工具已被用于生物研究1的许多领域。能够同时检测多种蛋白质在诊断液，如血液的抗体微阵列，具有在临床诊断和生物标志物筛选2-10重要的应用。唾液，含有许多相同的分析物如血，一直被认为是一个优选的替代方案，因为血液唾液收集是安全的，非侵入性的，并且可以进行通过微创医疗人员11-13。目前，使用唾液样本复用蛋白分析是由几个重要的因素，其中包括目标分析物14的低浓度和不同的生物标记物15的宽浓度范围的限制。 。 在此，我们证明6种蛋白的分析：人血管内皮生长因子（VEGF），干扰素γ-诱导蛋白10（IP-10），白细胞介素-8（IL-8），表皮生长因子（EGF），基质金属蛋白酶9（MMP-9），和白细胞介素-1β（IL-1β） 。该方法的性能用标准溶液构成的重组蛋白分析物和封闭缓冲液中最初验证。从不同的慢性呼吸系统疾病的患者以及健康对照真正的唾液样本进行了测试表现令人满意。该协议应当适用于其他蛋白质的分析物和其他基于微球的实验。该平台提供了相当大的优势，在分析化学领域，因为它使低浓度的几种蛋白质具有广泛的动态范围，最小的非特异性相互作用，减少样品消耗和低成本的快速，精确，可重复的和同时分析在比较的类似的酶联免疫吸附试验（ELISA）。
