  • Function

    Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. In macrophages and melanoma cells, isoform 5 may participate in the control of podosome and invadopodia formation.
  • Tissue specificity

    Isoform 5 is expressed in non-neuronal tissues, such as monocytes/macrophages.
  • Sequence similarities

    Belongs to the sodium channel (TC 1.A.1.10) family. Nav1.6/SCN8A subfamily.
    Contains 1 IQ domain.
  • Domain

    The sequence contains 4 internal repeats, each with 5 hydrophobic segments (S1,S2,S3,S5,S6) and one positively charged segment (S4). Segments S4 are probably the voltage-sensors and are characterized by a series of positively charged amino acids at every third position.
  • Post-translational

    May be ubiquitinated by NEDD4L; which would promote its endocytosis.
  • Cellular localization

    Membrane and Cytoplasmic vesicle. Some vesicles are localized adjacent to melanoma invadopodia and macrophage podosomes. Does not localize to the plasma membrane.

Thank you for sending the additional information and for your patience.

I forwarded your protocol details to the lab for a second look, and we would have expected the antibody to work in the conditions that you've described. I am very sorry that neither of these antibodies has worked for you, and I can arrange a credit or a refund for your original purchase if you'd like. Alternatively, we do have one other antibody that is predicted to work with rat samples, ab135457-


This antibody hasn't been tested with rat samples, but since the immunogen is homologous to the rat protein it may work. I'd be happy to send this out if you'd like to try it.

I apologize again for the poor results with these Nav1.6 antibodies, but if there is anything else that we can do for you, please let me know.

Thank you very much for keeping me updated about the results with ab65166.

I'm sorry to hear that there was still no band on the blot. Would you mind telling me some more about the protocol you used with ab65166?

1) Are you still using rat hippocampus lysates? How much protein was loaded per lane of the gel?

2) Could you describe the electrophoresis and gel conditions (% of the gel etc.)?

3) Could you describe the transfer and blocking conditions (buffer, transfer time, blocking agent etc.)?

4) Does the secondary antibody work with other primaries?

5) Detection method (ECL, ECLPlus etc.)

6) Did the ladder proteins transfer, or did you confirm transfer of the high molecular proteins via Ponceau stain?

We don't have any other antibodies to Nav1.6 that have been tested in Western blot with rat lysates, but I'll see if there are any protocol suggestions that we can make. If the results are still not satisfactory, we can arrange a credit or refund for your original purchase.

Please let me know if you have further questions or comments, and I'll be happy to help.

Thank you for your helpful advice. I used Ponceau S on my most
recent blot and was able to visualize transfer of both my MW marker
and proteins in my cell lysate. It's certainly possible, however,
I could be getting over-transfer to some extent. I recently contacted
the lab that wrote the review for ab65166 on your website, and they
said that they performed a 16 h transfer at 20 V. With the new lysate,
my hope is to try both your one hour transfer conditions and the 16 h
transfer conditions and see if I see better transfer with either.
I'd also be open to trying higher MeOH and lower SDS content;
although, the aforementioned group apparently used a basic transfer
buffer with 20% MeOH and no SDS.
I'm not currently blotting for a loading control, but that is
a good suggestion. The best evidence I have for the success of my
WB protocol is that I could visualize Invitrogen's Precision
Plus MW marker after incubation with my secondary antibody.
In terms of lysing my own sample, I used the following reference to
prepare my lysis buffer (http://www.springerprotocols.com/Full/doi/
I certainly am open to try other lysis buffers but felt it might
be best to use a formulation that had been used successfully with
these channels before.
I very much appreciate the offer to send me another vial of ab30151.
From some initial reading, it looks like Nav1.6 expression increases
during maturation, so it's perhaps best to stick with the lysate
I'm already using. The order number for the original order is

Thank you for your suggestions. In reviewing my previous blots, I
realized that all the ones I had run with the commercial cell lysate
had been stained with Amido Black, which made them unsuitable for
stripping and re-probing. I consequently ran another gel, loading
15 ug of ab30151 as well as the lysate for the system I'm trying
to study. I ran my transfer similar to before (75 V for 4 hours),
using 5% MeOH and 0.5% SDS in my transfer buffer, similar to your
suggestion. After transfer, I can see my MW marker (other company) fully transferred. I then pre-blocked with 3% BSA before
incubating with my primary antibody (ab65166) in 3% BSA overnight
at 4 oC. Finally, I incubated with the secondary antibody in 3%
BSA for 1 hour at room temperature and then did 3 10 minutes washes
with TBS-Tween before a final wash with TBS.
Upon visualization with my ECL+ kit, I only saw very high background
at moderate exposure times (1 minute) and couldn't see any signal
above background at very short exposure times (5-10 seconds). In
hindsight, I believe I should have incubated with the secondary
antibody in 10% milk.
I tried stripping the blot using the mild stripping protocol on
your website but still saw an almost equally strong background
upon visualization. At this point, I assume I must still have a
lot of secondary antibody non-specifically bound to the membrane,
so my next step is to try the harsh conditions.
Even though I see my full MW ladder transferred, I could definitely
believe that my transfer is still sub-optimal. I would like to try
alternative transfer conditions, but I have very little of my
remaining lot of ab30151 left. Would it be possible for me to obtain
another lot of this lysate at a discounted price? Alternatively, is
there another item in your catalog that you would recommend as a
positive control for the primary antibody that I could pay full price

Thank you for your reply.

I have a few additional suggestions. I am not sure if my colleague had mentioned those to you:

1) You can check the transfer with Ponceau S (which is a reversible membrane stain) to be sure that you transfered the proteins. This will give you also an additonal quality control for the transfer. My feeling is that transferingat 75V for 4 h could be too long. if the gel can withstand a higher voltage, I'd suggest to try 100V for an 1 h at 4 degree with stirring.

2) Further, I'd suggest to use 10% MeOH and reduce the amount of SDS to 0.1% in the transfer buffer. You want to have some SDS to prevent hydrophobic proteins (like Nav1.6) from precipitating in the gel during the transfer, but 0.5% seems a bit high.

3) Are you blotting for any other proteins, such as actin or tubulin as loading controls? This would be another way to check if the WB protocol in general works and if the mouse brain lysate you have is OK.

4) How are your samples lysed? I would recommend using RIPA buffer since the Nav1.6 protein is very hydrophobic.

I also checked online and found the following link for WB with membrane proteins:

Our WB protocol guide can be found here: https://www.abcam.com/index.html?pageconfig=resource&rid=11375and I have it also attached to this email.

To answer your question about the lysate:

I'd be happy to send you another vial of ab30151 free of charge. Alternatively, we also have ab7188 (Brain (Mouse) Tissue Lysate - normal tissue, 0 days old) [https://www.abcam.com/Brain-Mouse-Tissue-Lysate-normal-tissue-0-days-old-ab7188.html] in the catalog, but I am not certain if newborn mice express this protein strongly.
I can send you 1 vial of either one or the other free of charge. Please let me know which one you would prefer. Please let me know your order or PO number for the lysate.

I look forward to hear back from you and assist you further.

Thank you for calling and bringing this issue to our attention.

I just wanted to make sure you were loading the correct amount of protein and to make another suggestion regarding the blocking step.

For the brain lysate, ab30151, you will want to load at least 10ug, which is a volume of about 4 microliters.

For the blocking step, you may find that a relatively short block (30 minutes) instead of overnight, followed by overnight incubation with the antibody will help develop the signal, compared to an overnight block followed by a shorter incubation with the primary. These are little modifications, though. I suspect that either the lysate is defective or the transfer was not optimal. Please let me know how your tests go. If they fail, we will be happy to discuss a replacement of either the antibody or the lysate, or both.
