CIRBP encodes the Cold Inducible RNA Binding Protein, commonly known as CIRP. As an RNA-binding protein, it stabilizes target mRNAs and modulates translation, especially in response to cold stress. It regulates cellular processes like proliferation and apoptosis via interactions with pathways such as p53 and MAPK, mediating stress adaptation.
Dysregulated CIRBP is linked to cancers (e.g., hepatocellular carcinoma, breast cancer) where it promotes tumor growth and metastasis. It also contributes to neurodegenerative disorders like Alzheimer’s. Preclinical studies are exploring small molecule inhibitors targeting its RNA-binding domain to suppress oncogenic functions, showing early therapeutic potential.

CIRBP Recombinant Monoclonal Antibody (CSB-RA821323A0HU)
Validated Data
IHC image of CSB-RA821323A0HU diluted at 1:100 and staining in paraffin-embedded human breast 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 0.05% DAB.
IHC image of CSB-RA821323A0HU diluted at 1:100 and staining in paraffin-embedded human stomach 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 Hela cell with CSB-RA821323A0HU at 1:50, 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).
Overlay Peak curve showing A549 cells stained with CSB-RA821323A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/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 (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
