AQP4
AQP4,全稱為水通道蛋白4,常見別名有水通道蛋白-4、AQP-4、AQP4水通道蛋白,是一類主要表達于中樞神經系統星形膠質細胞、腎臟集合管上皮細胞的膜蛋白,是水通道蛋白家族的重要成員。它主要負責介導水分子的快速跨膜轉運,維持腦組織、腎臟等器官的水平衡,同時參與腦水腫形成、神經信號傳遞及腎臟尿液濃縮過程,保障機體相關器官的正常生理功能。
AQP4異常與多種疾病密切相關,最典型的是視神經脊髓炎譜系疾病,其相關抗體陽性是疾病診斷的重要標志,也與腦出血、腦梗死所致腦水腫、多發性硬化癥、腎臟尿濃縮功能障礙相關。目前相關研發聚焦于疾病診斷與靶向干預,相關檢測試劑已用于臨床疾病鑒別,針對其功能調控的抑制劑、抗體藥物正處于臨床前驗證及早期臨床試驗階段,為相關疾病的精準診療提供了新方向。

驗證數據
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
AQP4 Recombinant Monoclonal Antibody (CSB-RA548145A0HU)
驗證數據
IHC image of CSB-RA548145A0HU diluted at 1:50 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.33% DAB.

IHC image of CSB-PA11137A0Rb diluted at 1:370 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Immunofluorescence staining of U251 cells with CSB-PA11137A0Rb at 1:166, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
