      ab32034 staining p27 KIP1 in MCF7 cells treated with NS 398 (ab120295), by ICC/IF. Increase in p27 KIP1 expression correlates with increased concentration of NS 398, as described in literature.
      The cells were incubated at 37°C for 6h in media containing different concentrations of ab120295 (NS 398) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab32034 (1/100 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody.

    Question

    Thanks. I am also currently looking for a VEGF inhibitor and mostly they are for the receptor. Any chemical inhibitor in line with NS-398 should work fine for us. May be if I get one, I will let you know.

    Asked on Sep 14 2012

    Answer

    Thank you for your reply.

    That is the problem with this target. I have been able to find chemical inhibitors of VEGFR but not for VEGF. There seems to be mainly antibody inhibitors of VEGF. If you do find a compound you are interested in, please do let me know and I can see if we could consider adding it to the catalogue.

    I am sorry I could not be of more help in this instance. If you have any further questions, please do not hesitate to contact us again.

    Question

    I am looking for primary HO-1 antibody (Haem oxygnase) and COX-2 (mono or polyclonal , raised in rabbit against mouse, rat and human, applicability). Can you suggest some good ones. Also, I am looking for chemical inhibitors for COX-2 (NS-398) and VEGF (I actually don’t know the name of the inhibitor), can you tell me the availability of the same?

    Answer

    I hope your grant application is going well. We have several antibodies against the targets you have mentioned which may be of interest to you:

    HO-1

    I would suggest looking at the rabbit polyclonal https://www.abcam.com/Heme-Oxygenase-1-antibody-ab13243.html. This has been shown to react with human, mouse and rat samples and has been used in ICC, IHC-Paraffin embedded, sELISA and Western blotting to date. We also have a very popular mouse monoclonal https://www.abcam.com/Heme-Oxygenase-1-antibody-HO-1-1-ab13248.htmlwhich has also been used with human, mouse and rat samples as well as in ELISA, Flow Cytometry, ICC,IHC-Frozen sections, and Western blotting. Bit I think you were more interested in antibodies raised in rabbit.

    COX-2

    For this target I would suggest having a look at the rabbit polyclonal https://www.abcam.com/COX2--Cyclooxygenase-2-antibody-ab15191.html. This has again been tested with mouse, rat and human samples and has been used in ICC/IF, IHC-Frozen sections, IHC-Parrafin embedded, IP, sELISA and Westernblotting.

    We also have the NS-398 compound (COX-2 inhibitor) which is available under the catalogue number https://www.abcam.com/NS-398-ab120295.html.

    I am afraid I have not been able to find a similar inhibitor of VEGF. Do you have a particular compound in mind? It may be that I can suggest we start stocking it.

    I hope this information has been of help. If you have any further questions, please do not hesitate to ask.
