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 2% Bovine Serum Albumin before being incubated with ab7291 overnight at 4 C. Antibody binding was detected using ab205719, and visualised using ECL development solution ab133406. IHC image of alpha 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 ab7291 at 1/1000 dilution. An HRP-conjugated secondary (Ab205719, 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.*Tissue obtained from the Human Research Tissue Bank, supported by the NIHR Cambridge Biomedical Research Centre All lanes : Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) at 1 µg/mlLane 1 : Liver (Human) Tissue LysateLane 2 : Liver (Mouse) Tissue LysateLane 3 : Liver (Rat) Tissue LysateLysates/proteins at 10 µg per lane.SecondaryAll lanes : ab205719 (Left Image) at 1/5000 and a competitor secondary (Right Image) at 1/5000.

Antibody binding was detected using ab205719, and visualised using ECL development solution ab133406. Cross-reactivity of the polyclonal secondary antibody ab182017 was tested using a sandwich ELISA approach. The wells were coated with the indicated IgG standards at 1 g/ml (50 l/well) and incubatedovernight at 4 C, followed by a 5% BSA blocking step for 2h at RT. ab182017 was then added starting at 1 g/ml and gradually diluted 1/4 (50 l/well), followed by incubationfor 2h. For the detection Donkey anti-Goat IgG H L (HRP) (ab6885) was used at 1/10,000 dilution (50 l/well), followed by incubationfor 1h at RT.Fot the batch tested, ab182017 showed a cross-reactivity below 2% towards Chicken IgY, 6% towards Human IgG, 7% towards Rabbit IgG and 47% towards Rat IgG.This data was developed using the unconjugated antibody (ab182017). Cross-reactivity of Goat anti-Mouse IgG H L (ab182017)and Goat anti-Mouse IgG H Lobtained from two different vendors was tested using a sandwich ELISA approach. The wells were coated with the indicated IgG standards (Rabbit, Human, Mouse and Rat) at 1 g/ml(50 l/well) and incubatedovernight at 4 C, followed by a 5% BSA blocking step for 2h at RT. Secondary antibodies were then added starting at 1 g/ml and gradually diluted 1/4 (50 l/well), followed by incubationfor 2h. For the detection Donkey anti-Goat IgG H L (HRP) (ab6885)was used at 1/10,000 dilution (50 l/well), followed by incubationfor 1h atRT. This data is from a representative dilution.This data was developed using the unconjugated antibody (ab182017). To our knowledge, customised protocols are not required for this product.
