Slug (SNAI2) is a widely expressed transcriptional repressor and member of the Snail family of zinc finger transcription factors. Similar to the related Snail protein, Slug binds to the E-cadherin promoter region to repress transcription during development. The binding of Slug to integrin promoter sequences represses integrin expression and results in reduced cell adhesion. Down regulation of E-cadherin expression occurs during the epithelial-mesenchymal transition during embryonic development, a process also exploited by invasive cancer cells. The tumor suppressor protein p53 induces Slug expression in g-irradiated cells; Slug protects damaged cells from apoptosis by repressing p53-induced transcription of the proapoptotic Bcl-2 family protein Puma. Deletion mutations in the corresponding Slug gene are associated with the pigmentation disorders Waardenburg Syndrome and Piebaldism, while a genetic duplication resulting in Slug overexpression is associated with a collection of congenital heart defects termed tetralogy of Fallot.
Suitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested.
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
