Snail Overexpression Lysate Summary


Snail Transient Overexpression Lysate

Expression Host: HEK293T

Plasmid: RC204581

Accession#: NM_005985

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.


  • Western Blot
Application Notes
This product is intended for use as a positive control in Western Blot.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
Theoretical MW
28.9 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Lysate Details for Array



HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.This product is manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.

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 Lysate (NBL1-16265). (Showing 1 - 1 of 1 FAQ).

  1. 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.
    • 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.
