This product is a recombinant rabbit monoclonal antibody.
Our Abpromise guarantee covers the use of ab62331 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||1/100 - 1/250.|
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
|WB||1/500 - 1/1000. Detects a band of approximately 72 kDa (predicted molecular weight: 69 kDa).Can be blocked with COX2 / Cyclooxygenase 2 peptide (ab213704).|
Blocking and dilution buffer: 5% NFDM/TBST
Immunofluorescence staining of RAW264.7 cells with purified ab62331 at a working dilution of 1/200, counter-stained with DAPI. The secondary antibody was Alexa Fluor® 488 goat anti-rabbit (ab150077), used at a dilution of 1/1000. ab7291, a mouse anti-tubulin antibody (1/1000), was used to stain tubulin along with ab150120 (Alexa Fluor® 594 goat anti-mouse, 1/1000), shown in the top right hand panel. The cells were fixed in 100% methanol and permeabilized using 0.1% Triton X 100. The negative controls are shown in bottom middle and right hand panels - for negative control 1, purified ab62331 was used at a dilution of 1/500 followed by an Alexa Fluor® 594 goat anti-mouse antibody (ab150120) at a dilution of 1/500. For negative control 2, ab7291 (mouse anti-tubulin) was used at a dilution of 1/500 followed by an Alexa Fluor® 488 goat anti-rabbit antibody (ab150077) at a dilution of 1/400.
Unpurified ab62331 staining COX2 / Cyclooxygenase 2 in Mouse 14.5 dpc tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde, permeabilized with TBS-T and blocked with 1% BSA + 1% FBS in TBS for 2 hours at room temperature; antigen retrieval was by heat mediation in Tris buffer, pH9. Samples were incubated with primary antibody (1/100 in blocking buffer) for 16 hours. An undiluted HRP-conjugated Goat anti-rabbit IgG polyclonal was used as the secondary antibody.
Flow Cytometry analysis of HeLa (human cervix adenocarcinoma) cells labelling COX2 / Cyclooxygenase 2 with purified ab62331 at 1/80 (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/2000) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG. Blue - Unlabelled control, cells without incubation with primary and secondary antibodies.
Unpurified ab62331 staining HeLa cells by ICC/IF. The cells were fixed with paraformaldehyde and permeabilized with 0.5% Triton X100 in PBS. The cells were then stained with ab62331 at 1/200 in PBS for 1h at 22°C. An Alexa Fluro 488 goat anti-rabbit polyclonal antibody at 1/200 was used as the secondary antibody. Nuclei are stained in red with DAPI. ab62331 produces the expected cytoplasmic staining pattern.
