Background: Snail

Snail, also called SNAIL1 or SNAI1, is a zinc-finger transcription factor belonging to the Snail superfamily and encoded by the SNAI1 gene (1,2). Snail was first discovered in Drosophila and has homologs in many species including vertebrates and humans (1,2). The Snail family members includes Snail (Snail1), Slug (Snail2), and Smuc (Snail3) (1,2). In humans, Snail is expressed in a number of tissues including placenta, brain, and skeletal muscle, but is most highly expressed by the kidneys (1). Snail functions in repression of E-cadherin transcription which is associated with epithelial-mesenchymal transition (EMT) that is especially prominent during embryonic development (1-5). Along with Snail, other related EMT-inducing transcription factors (EMT-TFs) include the Twist and ZEB protein families (3). Snail is synthesized as a protein of 264 amino acids (aa) with an N-terminal SNAG domain, a serine-rich domain (SRD), nuclear export sequences (NES), and four C-terminal zinc-finger binding domains, with a theoretical molecular weight of 29 kDa (1,3). Snail activity is largely regulated through post-translational modifications such as phosphorylation, ubiquitination, and glycosylation, which impacts Snail's localization and stability, amongst other things (1-3, 5).

In addition to its role in embryonic development, Snail-induced EMT is also associated with cancer metastasis (1-5). Snail is expressed in a variety of cancer lines including breast cancer, cervical carcinoma, and colorectal carcinoma, and typically results in increased migration, invasion, and metastasis (1). Accordingly, Snail expression is also correlated with drug resistance and tumor recurrence (1-5). Chemical inhibitors that target Snail have shown some promise in reducing or eliminating Snail-induced EMT, increasing E-cadherin expression, and increasing tumor regression (1).

FAQs for Snail Antibody - BSA Free

Showing  1 - 2 of 2 FAQs Showing All

  • Q: Could you please let me know the secondary antibody recommended for this particular primary antibody (Catalog NumberNBP2-27293) so that I could order both primary & secondary antibodies.

    A: Our SNAIL antibody with catalogue number NBP2-27293 is a rabbit polyclonal, and as such you would require an anti-rabbit secondary to detect it. You can see our full range of anti-rabbit secondary antibodies at the following link, and by using the search filters at the left hand side of the webpage you can select a suitably conjugated product for your research: View Secondary Antibodies

  • Q: There are many kinds of antibodies you supply against SNAIL. Could you give me your recommendation? Which is the best for the IHC-P experiments the species of my samples to be tested is human.

    A: Our SNAIL antibody with catalog # NBP1-19529 has been successfully validated for IHC-P in paraffin-embedded human lung carcinoma tissue and I would highly recommend you to use the same for your samples too. The working dilutions of this antibody for IHC-P ranges from 1:50 - 1:200 and beside IHC, you can use this antibody for Western Blot and Immunofluorescence also.
