靶标

  • 功能

    Required for brain and eye development. Promotes the disassembly of phosphorylated vimentin intermediate filaments (IF) during mitosis and may play a role in the trafficking and distribution of IF proteins and other cellular factors to daughter cells during progenitor cell division. Required for survival, renewal and mitogen-stimulated proliferation of neural progenitor cells.

  • 组织特异性

    CNS stem cells.

  • 序列相似性

    Belongs to the intermediate filament family.

  • 发展阶段

    Upon terminal neural differentiation, nestin is down-regulated and replaced by neurofilaments.

  • 翻译后修饰

    Constitutively phosphorylated. This increases during mitosis when the cytoplasmic intermediate filament network is reorganized.

    Question


    Inquiry: I ordered the RabMAb Anti-nestin antibody and I tested it using conditions recommended in the spec sheet for ICC/IF (1:200). I used this antibody at the same time as some other nestin antibodies from other companies, so I know the cells (human glioblastoma stem cells) express a lot of nestin. And I was also testing the RabMab anti-GFAP antibody (ab68428) at the same time, and this antibody worked really well. I have since repeated the experiment using different antibody concentrations and still have negative results (I get no signal). I am using the Alexafluor goat anti- rabbit 488 secondary antibody and again I was testing other rabbit antibodies at the same time and it worked at the concentration I used (1:250). My protocol is: 1. Fix in 8% PFA added directly to cells in culture media in a 1:1 ratio so it's diluted to 4% 2. wash 3. Permeabilize with 0.1% Triton-x-100 4. wash 5. Block in 10% goat serum 6. Add primary antibody in blocking solution for 1 hr at RT (I've gone as low as 1:100) 7. wash 8. Add secondary antibody in blocking solution for 1 hr at RT 9. wash 10. Add Hoescht 33342 I tried to be as detailed as possible, but please let me know if you need anymore info about my experiment. Thanks for your help.

    Answer

    Thank you for contacting us. I am sorry to hear that this antibody is not providing satisfactory results.

    The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.

    Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab105389. I would also appreciate if you can confirm some further details:

    1) How long did you permeabilize with Triton?

    2) Overnight incubation was used in the image on our datasheet. This is usually the best way to get a strong signal in your cells.

    Should the suggestions not improve the results, please do let me know.

    In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund.

    I hope this information is helpful, and I thank you for your cooperation.

    Question

    I have a question regarding one of you anti-Nestin antibodies ( ab105389 ).  On the website it lists this antibody as reacting with human, but doesn't provide any informatin regarding mouse.  I looked at a number of other Nestin antibodies and some react with both mouse and human, and some are specific to one or the other (for example a mouse ab that lists as "doesn't react with human").  I was wondering if based on the antigen used for this antibody if it if would or wouldn't react with mouse.

    Answer

    Thank you for contacting us.

    Unfortunately, alignments of the immunogen with mouse show very poor homology. As such, we cannot guarantee or recommend this product for use in this species. We do offer a number of other anti-Nestin antibodies of which nine are tested and guaranteed in mouse samples. In general, I would recommend Anti-Nestin antibody [2Q178] - Neural Stem Cell Marker (ab6142) as this product is extensively tested, published with and reviewed. However, I would be happy to help find the right product for you based on your needs.

    More information about ab6142 may be found at this location: https://www.abcam.com/nestin-antibody-2q178-neural-stem-cell-marker-ab6142.html

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