Rabbit IgG, whole molecule
HRP conjugated anti-rabbit secondary antibody optimized for western blot and immunohistochemistry. Some customers reported seeing brown precipitates in the vials. The brown precipitates are very common with HRP conjugated antibodies; we suggest vortexing the vial and using this antibody as normal. Our customer’s feedback says the antibody worked great. If in case the antibody fails to give results then please contact our Scientific Support team for assistance.
Our Abpromise guarantee covers the use of ab6721 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/2000 - 1/20000.
Suggested working dilution of 1/3000 (see PMID: 17222046). In addition, found to work at 1/20000 (see PMID: 16936283).
Working dilutions are highlighted in the table below. Please note that the antibody can be diluted to 1:48,000 to 1:207,000 in many instances.
|Immunomicroscopy||Use at an assay dependent concentration.|
|Dot blot||Use at an assay dependent concentration.|
|ICC||1/1000 - 1/5000.|
Blocked with 5% non-fat Milk for 1 hour at 18°C
Immunohistochemical analysis of PFA-fixed paraffin-embedded rat cardiac tissue sections, labelling Conexin 43 with ab117843 at a dilution of 1/500 incubated for 12 hours at 4°C in 1% BSA in TBS. Antigen retrival was via Tris-EDTA pH 9.0 (heat mediated). Blocking was 3% BSA incubated for 1 hour at 37°C. The secondary was ab6721 at 1/500.
ab3580 staining glucocorticoid receptor in mouse epididymis tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with bouin's solution and blocked with 1.5% serum for 30 minutes at 25°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/1000) for 14 hours at 4°C. A HRP-conjugated goat anti-rabbit IgG H&L (ab6720) (1/200) was used as the secondary antibody.
