Western blot - Donkey Anti-Rabbit IgG H&L (HRP) (AB205722)

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 3% milk before being incubated with ab68153 overnight at 4°C. Antibody binding was detected using ab205722, and visualised using ECL development solution ab133406.

Western blot - Donkey Anti-Rabbit IgG H&L (HRP) (AB205722)

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 incubated overnight with 2% Bovine Serum Albumin at 4°C. Any non-specific background binding was assessed by incubating the membrane with only the secondary antibody (ab205722), and visualised using ECL development solution ab133406.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Donkey Anti-Rabbit IgG H&L (HRP) (AB205722)

IHC image of beta tubulin staining in a section of formalin-fixed paraffin-embedded normal human colon tissue*. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins, and incubated overnight at +4°C with ab6046 at 5ug/ml. An HRP-conjugated secondary (ab205722, 1/10000 dilution) was used to detect the primary for 1hr at room temperature. DAB was used as the chromogen (ab103723), diluted 1/100 and incubated for 10min at room temperature. The section was counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ELISA - Donkey Anti-Rabbit IgG H&L (HRP) (AB205722)

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).
