The Abpromise guarantee
Our Abpromise guarantee covers the use of ab175731 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Anti-beta Tubulin antibody - Loading Control (ab6046) at 1 µg/ml + HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate at 10 µg
Donkey Anti-Rabbit IgG H&L (Alexa Fluor® 750) (ab175731) at 1/10000 dilution
Observed band size: 50 kDa why is the actual band size different from the predicted?
This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Milk before being incubated with ab6046 overnight at 4°C. Antibody binding was detected using ab175731 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.
Cross-reactivity of the polyclonal secondary antibody ab182020 was tested using a sandwich ELISA approach. The wells were coated with the indicated IgG standards at 1 µg/ml (50 µl/well) and incubated overnight at 4°C, followed by a 5% BSA blocking step for 2h at RT. ab182020 was then added starting at 1 µg/ml and gradually diluted 1/4 (50 µl/well), followed by incubation for 2h. For the detection Goat anti-Donkey IgG H&L (HRP) (ab6988) was used at 1/20,000 dilution (50 µl/well), followed by incubation for 1h at RT.
For the batch tested, ab182020 showed a cross-reactivity below 2% towards human IgG, mouse IgG, rat IgG, goat IgG and chicken IgY.
This data was developed using the unconjugated antibody (ab182020).
