Target

  • Function

    Cytokine that binds to TNFRSF11B/OPG and to TNFRSF11A/RANK. Osteoclast differentiation and activation factor. Augments the ability of dendritic cells to stimulate naive T-cell proliferation. May be an important regulator of interactions between T-cells and dendritic cells and may play a role in the regulation of the T-cell-dependent immune response. May also play an important role in enhanced bone-resorption in humoral hypercalcemia of malignancy.

  • Tissue specificity

    Highest in the peripheral lymph nodes, weak in spleen, peripheral blood Leukocytes, bone marrow, heart, placenta, skeletal muscle, stomach and thyroid.

  • Involvement in disease

    Defects in TNFSF11 are the cause of osteopetrosis autosomal recessive type 2 (OPTB2) [MIM:259710]; also known as osteoclast-poor osteopetrosis. Osteopetrosis is a rare genetic disease characterized by abnormally dense bone, due to defective resorption of immature bone. The disorder occurs in two forms: a severe autosomal recessive form occurring in utero, infancy, or childhood, and a benign autosomal dominant form occurring in adolescence or adulthood. Autosomal recessive osteopetrosis is usually associated with normal or elevated amount of non-functional osteoclasts. OPTB2 is characterized by paucity of osteoclasts, suggesting a molecular defect in osteoclast development.

  • Sequence similarities

    Belongs to the tumor necrosis factor family.

  • Post-translational
    modifications

    The soluble form of isoform 1 derives from the membrane form by proteolytic processing (By similarity). The cleavage may be catalyzed by ADAM17.

The cells were 4% formaldehyde fixed (10 minutes) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab45039, 10 µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1 hour. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1 hour. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 µM.

    Question

    our customer told us that a control can not solve her problems. It could be useful only for the difference between the expected and observed molecular weight (in our case relative to RANKL antibody), but also in that case she's sure that there was no problem in gel running and the molecular weights were indeed those identified by the standard, because after revealing RANKL they have also revealed actin, with the band showing the expected length. Moreover, your the use of a control does not resolve the problem of OPG and ATF4 aspecificity. For this reason, she has requested the substitution of items ab10962, ab23760, ab45039. Please could you let us know when you should ship us these antibodies in substitution? Our customer needs them urgently.  

    Read More
    Answer

    Thanks for your reply. It seems that, as part of their own internal QC, the customer has already peformed the control I suggested. This is great as it does appear clear now that these 3 antibodies are not working as expected. I would be happy to request the replacement antibodies the customer asked for: 1 vial each of ab10962, ab23760, ab45039. So I can process the request, please let me know the purchase order number or Abcam order reference number associated with the initial order of these 3 antibodies. Thanks!

    Thank you for your reply.

I am sorry to confirm we have no RANK antibodies tested in rat. Regrettably I am not able to find the correct rat sequence on the protein database sites, and so am not able to check the alignments with rat.  If you have access to the rat sequence, I can suggest to try alignment to the immunogen for these antibodies. We recommend alignment should be over 85% to predict that an antibody will detect in a different species. I am sorry we also do not have an antibody tested and guaranteed in both IHC and flow cytometry. If you would like to test one of the antibodies in one of these untested applications, we would be able to provide a testing discount offer. Please let me know if you are interested, and I will be pleased to forward the details. This also applies to the rat species. If the alignment is over 70% , we would be able to provide a testing discount for you to try in rat. I am sorry we do not have an antibody that is tested to meet all your requirements on this occasion, but I hope these ones will still be of interest to you.  If you have any further questions, or are interested in the testing discount, please do not hesitate to contact me.

    Question

    What species of bone cells were being tested?   Murine Osteoblasts from calvaria What dilution of primary antibody for each?   OPG 1:100; ATF4 1:400; RANKL 1:500 Was any other antibody used successfully with these same samples?  No How much protein was loaded on the gel? 20 ug   Please, could you tell us when you'll ship us the antibodies in substitution?  

    Read More
    Answer

    Thank you for providing the additional information. The one thing I would like to recommend in this case is to run a "loading control" western blot with the murine osteoblast cell lysate. Examples of targets for this type of control would be proteins that are commonly expressed at high levels in all cell types, such as actin or GAPDH. This would serve as a control in that detection of the expected band size would indicate that all aspects of the lysate preparation and western blot protocol are working as expected. Thanks so much for your troubleshooting efforts! I look forward to hearing how things go.

    Question

    the last June our company Aurogene ordered from you the antibodies ab10962 goat polyclonal to Osteoprotegerin, ab23760 rabbit polyclonal to ATF4 and ab45039 mouse monoclonal |12A668| ro RANKL, that didn't work when used by our customer. In attachment we send you the WB images of these antibodies. The experiments were performed using lysates of bone cells that certainly synthesize proteins for which the above antibodies should be specific. As for the first 2, the customer has found a strong aspecificity, while for RANKL he has seen a single band, but the found molecular weight (65 kDa approximately) is much higher than expected (35 kDa). Please, could you substitute as soon as possible these antibodies?

    Answer

    Thank you for your enquiry regarding ab45039 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody. I can confirm that anti RANKL antibody is indeed specific to mouse tissue sections. This antibody is fully guaranteed to be used on mouse tissue sections however with additional blocking steps for mouse on mouse use. I have read the protocol you have kindly provided and I have following comments/ suggestions to make; In negative control samples you have mentioned that you have observed a brown staining with no primary antibody control, this means the anti mouse secondary is actually binding to the endogenous mouse IgG which is giving back ground staining. Please find attached pdf file in which additional blocking steps are nicely explained. https://www.abcam.com/index.html?pageconfig=resource&rid=11465 I am sure these suggestions will help to improve your results. Should you have any questions or concerns please do not hesitate to contact me.
