La neurofibromatose de type 1 (NF1), ou neurofibromatose de von Reckinghausen, est l'une des maladies autosomiques dominantes les plus courantes chez l'homme. Une première analyse de liaison a permis de localiser le gène NF1 sur le chromosome 17. Le transcrit prédit de la NF1 code pour la protéine Neurofibromine, d'une taille de 2 818 acides aminés, également appelée protéine NF1-GAP (NF1GRP). L'analyse des séquences a démontré une similarité entre une petite région de la neurofibromine et les membres de la famille des gènes Ras GAP. Sur le plan fonctionnel, l'analyse biochimique impliquant l'hydrolyse de RAS-GAP et la complémentation fonctionnelle dans la levure ont montré que la neurofibromine ressemblait davantage à la protéine GAP. La protéine Neurofibromine est exprimée à des niveaux relativement constants dans un large éventail de lignées cellulaires et de tissus, notamment le cerveau, les poumons, le foie, les reins, la rate, les muscles et le côlon. Bien que la fonction de la Neurofibromine soit peu connue, l'homologue avec le domaine catalytique des protéines ayant une activité GTPase suggère que la Neurofibromine pourrait également interagir in vivo avec les protéines Ras.

I am using Neurofibromin (McNFn27a): sc-20017 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Rated 5 de 5 de par This antibody genuinely *does* work (even on WB)Hi. I am first author of one of the cited publications for this antibody (at least my pub still listed as 08/2025; Kahen, E. et al.) and I noticed someone else said they could not get signal on WB in their hands. I want to reassure that you really can get great WB's with this antibody for any human cell line, but it is a labor of love. Neurofibromin is a fairly large protein as you likely know, (typically considered 240 kd) often running somewhere around 210-240 kda range on a gel per MW markers. As I wrote in my methods, I had to use a tris-acetate gradient gel of 3-8% to capture NF1 and its putative isoform explicitly (Very painful gel to deal with; many gels were broken during troubleshooting). Getting the loading control was tricky because tubulin would run around the same range as a non-specific band. Alpha-actinin ran *very close* to a non-specific band so was not "publication worthy" but was good for testing, and was used, and others might benefit from this using alpha-actinin for loading control for NF1 if new antibodies more specific. I had to find perfect timing to be able to capture proper *actin* right at the bottom of the gel, which has far more specific WB antibodies for pub-worthy images. Note: Wet transfer 100% necessary to get all the NF1. Dry transfer would either over-transfer the actin or (most often) under-transfer the NF1. Very difficult to get sufficient NF1 on a membrane via dry-transfer without losing other bands for controls (and I was also really trying to get RAS on same gel). Honestly I think I legit tried dry transfer for a hilarious amount of time once and when I stained the gel out of curiosity, there was *still* so much protein in the NF1 region. I really tried many times with dry transfer- wet transfer only way to get anything useful. Then, I actually blocked membranes *overnight* in Odyssey blocking buffer. This Santa-Cruz NF1 antibody was then used at highest concentration recommended by manufacturer, again in Odyssey blocking buffer *overnight* (4degC on shaker). Very thorough washing in TBST (and I think I actually preferred lower tween 20 % but 10 min washes). I really wanted clean crisp neurofibromin showing two bands, as I did. And ultimately, I was able to get the result I wanted and reproduce it (though actin could really have looked a little prettier, but quantified accurately overall.) I suppose we should really be this detailed in our methods, explaining these sorts of things, but we tend not to be. Nonetheless, what I've described might help someone working with this antibody. Feel free to reach out via email and I will try to remember my best other than what I've written here.
