The area of BPIFA1 peak, in relation to the standard curve, was determined and virtual blot-like images were generated using Compass software (ProteinSimple).An innate defense peptide BPIFA1/SPLUNC1 restricts influenza A virus infection, Mucosal Immunology volume 11, pages 71–81(2018).2. 脑脊液（肺炎链球菌脑炎病人）Quantitative western blottingAutomatic western blots were performed using a Wes automated system (ProteinSimple, California, USA). Purified recombinant proteins were used as calibration standards. Serial dilutions of both sample and standard were used to determine the linear dynamic range of the assay. Additionally, the optimal concentration of each antibody for use in the Wes system was determined, as this can differ from that used in traditional western blot. Samples (20 SPP, 15 hospital controls and 5 healthy controls) were mixed with a 5x sample buffer containing SDS, DTT and fluorescent molecular weight standards and heated at 95 °C for 5 min and then, loaded onto a plate prefilled with stacking and separation matrices, along with blocking and wash buffers, antibody solutions and detection reagents. Default settings were used for the analysis.Quantitative Proteomics of Cerebrospinal Fluid in Paediatric Pneumococcal Meningitis, Scientific Reports volume 7, (2017).Wes/Jess 全自动定量Western Blot特点         n  全程自动化，无需检测人员值守         n  从样本到结果，全程3小时         n  标准曲线定量检测病人样本靶蛋白浓度         n  微量样本         n  数据可追溯         n  自动数据计算存储
