• Description: IL-27/P28 antibody
• Species/Host: Rat
• Clonality: Monoclonal
• Clone Number: 3H12.F10
• Tested applications: ELISA, FC, Multiplex Assay, WB
• Reactivity: Mouse
• Isotype: IgG2a
• Immunogen: Anti-IL-27/p28 monoclonal antibody was produced in rats by repeated immunizations with mature length recombinant mouse p28 protein (produced in E.coli) followed by hybridoma development.
• Concentration: 1.0 mg/mL
• Dilution range: ELISA: 1:10,000, FC: 1 ug / ml, WB: 1:1000
• Form/Appearance: Liquid (sterile filtered)
• Purity: IL-27 / p28 antibody is purified by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. This antibody is specific for mouse and rat p28 protein. Cross-reactivity with IL-27 from other sources has not been determined.
• Conjugation: Unconjugated
• UniProt ID: Q8K3I6
• NCBI: NP_663611.1
• Storage: Store vial at -20° C or below. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
• Buffer/Preservatives: 0.01% (w/v) Sodium Azide
• Alternative names: rat anti-IL-27/p28 antibody, rat anti-interleukin
• Note: For research use only
• Application notes: IL-27 is expressed in activated antigen presenting cells including monocytes, endothelial cells, and dendritic cells, for example mouse CD4 splenocytes. This purified antibody has been tested for use in Flow Cytometry, ELISA and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 26 KDa in size corresponding to the mature mouse p28 protein, a non-glycosylated polypeptide chain consisting of amino acids, by western blotting in appropriate cell lysate or extract.
• Expiration Date: 12 months from date of receipt.

Anti-IL-27/p28 antibody in western blot shows detection of recombinant mouse IL-27/p28. Recombinant protein (0.1 µg) was loaded on to an SDS-PAGE gel, and after separation, transferred to nitrocellulose. The expected band is approximately 26 kDa in size. The membrane was blocked with 1% BSA in TBST for 30 min at RT, followed by incubation with Biorbyt's Anti-IL-27/p28 antibody diluted 1:1000 in 1% BSA in TBST overnight at 4°C. After washes, the blot was reacted with secondary antibody HRP Goat anti-Rat IgG antibody (p/n orb347790) diluted 1:40000 in blocking buffer (p/n orb348637) for 30 min at RT.

Mouse peritoneal macrophages were grown in culture for 24 hours, stimulated with 10 ng/mL IFN gamma and 1 ug/ml LPS for 14 hours and incubated for 4 hours with Bredfeldin A. Cells were harvested, washed, aliquoted 1x106 cells per sample, and fixed and permeabilized according to a standard protocol. Samples were stained with biotinylated primary anti-mouse p28 antibody at (0.1-10 ug/ml primary antibody alongside negative controls of unstimulated cells and isotype controls. Cells were stained with 0.25 ug/ml rat anti-mouse CD107b conjugated Alexa Fluor 647 and PHYCOERYTHRIN Conjugated secondary at 1:100 and analyzed by flow cytometry. Stimulated cells showed increase PE staining (horizontal axis) when compared with unstimulated cells.
