  • Relevance

    ARID1B (AT-rich interactive domain-containing protein 1B) is a component of SWI/SNF chromatin remodeling complexes involved in transcriptional activation and repression of select genes by chromatin remodeling. It binds DNA non-specifically and alters DNA-nucleosome topology.

  • ICC/IF image of ab57461 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab57461, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    This image was generated using the ascites version of the product.

  • ARID1B antibody (ab57461) used in immunohistochemistry at 3ug/ml on formalin fixed and paraffin embedded human kidney.

    This image was generated using the ascites version of the product.

  • ARID1B antibody (ab57461) at 1ug/lane + HeLa cell lysate at 25ug/lane.

    This image was generated using the ascites version of the product.

  • Overlay histogram showing HEK293 cells stained with ab57461 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab57461, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

    This image was generated using the ascites version of the product.

Lot number: GR94192-1
Inquiry: GENERAL INFORMATION Antibody Storage Conditions (temperature/reconstitution etc) As instructed. -20°C and freeze/thaw was avoided Description of the Problem (high background, wrong band size, more bands, no bands etc) Wrong band size. 2 non-specific bands between 52kDa and 30kDa Sample (Species/Cell extract/Purified protein/Recombinant protein, etc) HEK293FT, BE2-M17 neuroblastoma and human fibroblasts lysates. Sample Preparation (Buffer/Protease inhibitors/Heating sample etc.) Lysed immediately with 50mM Tris, pH 6.8, 5% SDS, 50mM EDTA on the culture plate. Sample was then sonicated to shear genomic DNA. Protein concentration was measured and appropriate amount was then mixed with the required volume of 5X SDS-PAGE sample loading buffer Amount of protein loaded 80ug Electrophoresis/Gel Conditions (Reducing or non-reducing gel, % of the gel etc.) Reducing, 10% polyacrylamide Transfer and blocking conditions (Buffer/time period, Blocking agent etc) 10v, overnight wet transfer for 16.5 hrs.

Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

I have read the details you have kindly provided and have following further questions for better understanding of the problem;

- Could you confirm if the immunoprecipitation has been done or not?
- Have you used any loading control?

Suggestions for further improvements;

-Could you try the lysates without sonicating?

Thank you very much for your cooperation. I will look forward to hearing from you soon.
