一种肺炎球菌抗体检测能够在单个反应中确定14种血清型。这种新研发的多通路系统是一种开放结构的、多种分析技术平台，能够迅速、准确而经济的给出生物检测的结果。

       这种多通路间接免疫荧光分析方法能够同时检测肺炎球菌多聚糖(PnPs)血清IgG浓度，包括14种PnPs血清型：1, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 12F, 14, 18C, 19F和23F。

       Luminex生物科学集团(LBG, Austin, TX, USA)已经宣布这种检测方法投放市场，这种方法是以该公司的多重分析轮廓系统(xMAP)为基础的。能够在现在使用的Luminex设备上使用。这种生物检测方法与酶联免疫吸附试验(ELISA)结果具有良好的一致性，ELISA方法目前被推荐用于肺炎球菌疫苗免疫活性的评估。
 
       Pneumococcal Assay Determines 14 Serotypes Simultaneously 
 
       A pneumococcal antibody assay can determine 14 serotypes in a single reaction vessel. The newly developed multiplexing system is an open-architecture, multi-analyte technology platform that delivers fast, accurate, and cost-effective bioassay results.

       The multiplexed indirect immunofluorescent assay for pneumococcal polysaccharides (PnPs) simultaneously determines serum IgG concentrations to 14 PnPs serotypes: 1, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 12F, 14, 18C, 19F, and 23F.

        The Luminex Bioscience Group (LBG, Austin, TX, USA) announced the market release of the assay, which is based on the company抯 multiple analyte profiling system (xMAP). It can be used on the existing installed base of Luminex instrumentation. The bioassay showed good overall agreement with the enzyme-linked immunosorbant assay (ELISA) that is currently recommended for evaluation of pneumococcal vaccine immunogenicity.
