一種肺炎球菌抗體檢測能夠在單個反應中確定14種血清型。這種新研發的多通路系統是一種開放結構的、多種分析技術平臺，能夠迅速、準確而經濟的給出生物檢測的結果。

這種多通路間接免疫熒光分析方法能夠同時檢測肺炎球菌多聚糖(PnPs)血清IgG濃度，包括14種PnPs血清型：1, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 12F, 14, 18C, 19F和23F。

Luminex生物科學集團(LBG, Austin, TX, USA)已經宣布這種檢測方法投放市場，這種方法是以該公司的多重分析輪廓系統(xMAP)為基礎的。能夠在現在使用的Luminex設備上使用。這種生物檢測方法與酶聯免疫吸附試驗(ELISA)結果具有良好的一致性，ELISA方法目前被推薦用于肺炎球菌疫苗免疫活性的評估。
 
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.
