  • ATP6V1B2 was immunoprecipitated using 0.5mg Mouse Testis tissue lysate, 5µg of Rabbit polyclonal to ATP6V1B2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Mouse Testis tissue lysate lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab73404.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 57kDa; ATP6V1B2
  • ICC/IF image of ab73404 stained PC12 cells. The cells were 100% methanol fixed (5 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 (ab73404, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 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 antibody also gave a positive result in 4% PFA fixed (10 min) PC12 cells at 5µg/ml.
  • IHC image of ATP6V1B2 staining in human hippocampus formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab73404, 0.5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
  • ab73404 staining RAt incisor tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 2.5% serum for 30 minutes at 22°C. Samples were incubated with primary antibody (1/1000 in 1% BSA/ 0.5% Triton X-100 in PBS) for 16 hours at 4°C. An undiluted peroxidase-conjugated Goat anti-rabbit IgG polyclonal was used as the secondary antibody.

Thank you for contacting Abcam.

The exact immunogen sequence for ab73404, but I can say the antibody will bind between amino acids ***.

Since it is polyclonal antibody, it will most likely bind to multiply sites within that region.

If there is anything else I can help you with, please let me know.

Thank you for contacting us.Generally polyclonal antibodies are not epitope tested because they will bind many different places and not at a single site like a monoclonal antibody will do.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
