目前蛋白質組學耗材成本高昂。

現有蛋白質組學方法需要很高的技術門檻。

需要建立簡單易用和隨時可用的方法。

Empore™ E系列技術簡介

E3™技術特點

高效：手動操作時間<15min；
穩定：與多種細胞裂解條件兼容（例如：尿素、SDS、RIPA、TFA等）；
經濟：彌補基因組學和蛋白質組學產品之間的差距；
易用：對入門級生物醫學工作者零技術障礙；
多樣：E3tips™、E3filter™和E3plate™可滿足不同的樣品體積、濃度、數量和自動化的需求；
簡便：無需液體轉移，無需考慮任何與游離磁珠相關的問題（蛋白與磁珠的比例、磁珠粘附在管壁和表面、交叉污染等）；
Empore™產品服務于蛋白組學領域20多年，有深厚的應用基礎。

E3filter測試結果

Fig.1 Qualitative and quantitative assessment of E3technology (E3 filter) for E. coli proteome analysis. (A-C) Comparison of the number of proteins, peptides, and PSMs between the E3filter, FASP, and SP4-GB approaches. Error bars represent three replicates. (D-E) Overlapping analyses of proteins and peptides derived from the three methods. (F) Coefficient of variation of quantified proteins by the three methods. (G) Coefficient of variation of quantified peptides. (H) Pearson correlation between replicate experiments and different methods. (I) Percentages of missed cleavages. (J-K) Volcano plot of showing significantly differential proteins between the three methods. The two curves show FDR 0.05 and 0.01, respectively. (L) Heatmap of the overall quantified proteins by the three methods. FASP, filter aided sample preparation; SP4, Solvent Precipitation SP3; GB, glassbeads.
