BPI
BPI,全稱為殺菌通透性增加蛋白,常用別名內毒素中和抗菌蛋白。它主要儲存于中性粒細胞胞質當中,能夠特異性結合革蘭氏陰性菌內毒素,具備強效廣譜抗菌、中和毒性內毒素、減輕炎癥損傷等多重作用,是機體天然固有免疫防御體系中至關重要的保護分子。
BPI 體內表達水平不足或功能缺陷,會導致機體抵抗力下降,極易發生嚴重細菌性感染、膿毒癥、內毒素血癥,引發全身劇烈炎癥反應與多組織器官損傷,危及生命安全。重組 BPI 蛋白藥物曾進入臨床研究驗證療效,目前新一代優化型重組蛋白、小分子模擬激動物均處于臨床前開發階段,為重癥細菌性感染、膿毒癥救治提供全新高效治療方案。

Recombinant Human Bactericidal permeability-increasing protein (BPI) (CSB-EP002783HU)
驗證數據
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
BPI Recombinant Monoclonal Antibody (CSB-RA175604A0HU)
驗證數據
IHC image of CSB-RA175604A0HU diluted at 1:100 and staining in paraffin-embedded human tonsil tissue 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 0.05% DAB.
Immunofluorescence staining of THP-1 cell with CSB-RA175604A0HU at 1:50 ,counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Fluorescein Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
