Periostin (POSTN), also known as osteoblast-specific factor 2 (OSF-2), is a matricellular protein. It plays a crucial role in cell adhesion, migration, and proliferation. POSTN interacts with integrin receptors on the cell surface, activating intracellular signaling pathways such as the PI3K/Akt and MAPK pathways.
This protein is associated with various diseases, including cancer, fibrosis, and cardiovascular diseases. In cancer, POSTN promotes tumor growth, invasion, and metastasis. Regarding drug development, there are ongoing pre - clinical and clinical studies targeting POSTN to develop novel therapeutic agents for these diseases.
POSTN Recombinant Monoclonal Antibody (CSB-RA119753A0HU)
Validated Data
IHC image of CSB-RA119753A0HU diluted at 1:50 and staining in paraffin-embedded human liver 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 0.31% DAB.
Overlay Peak curve showing 293T cells stained with CSB-RA119753A0HU (red line) at 1:50. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-rabbit IgG(H+L) at 1:200 dilution for 35min at 4℃.Control antibody (green line) was rabbit IgG (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
