BPI, full name bactericidal/permeability-increasing protein. It is an innate immune protein in neutrophils, which binds bacterial endotoxin, exerts antibacterial effects and relieves systemic inflammatory injury.
BPI deficiency leads to severe bacterial infection and life-threatening sepsis. Recombinant BPI analogs are under preclinical development for infection and sepsis treatment.
Recombinant Human Bactericidal permeability-increasing protein (BPI) (CSB-EP002783HU)
Validated Data
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
BPI Recombinant Monoclonal Antibody (CSB-RA175604A0HU)
Validated Data
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).
