Product Info

• Predicted Species Reactivity: Human papillomavirus type 18
• Product Format: Liquid or Lyophilized powder
• Host: Human
• Additional Information: Protein Description: Full length
  Subcellular Location: Host cytoplasm, Host nucleus
• Reconstitution and Storage: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20C/-80C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20C/-80C. The shelf life of lyophilized form is 12 months at -20C/-80C.
  Repeated freezing and thawing is not recommended. Store working aliquots at 4C for up to one week.
• Purification: Affinity purified using IMAC
• Concentration: Varies by lot. See vial for exact concentration.

Target Info

• Gene Symbol: E7
• Alias Symbols: E7Protein E7
• Description of Target: E7 protein has both transforming and trans-activating activities. Disrupts the function of host retinoblastoma protein RB1/pRb, which is a key regulator of the cell cycle. Induces the disassbly of the E2F1 transcription factors from RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Inactivation of the ability of RB1 to arrest the cell cycle is critical for cellular transformation, uncontrolled cellular growth and proliferation induced by viral infection. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. Interferes with histone deacetylation mediated by HDAC1 and HDAC2, leading to activation of transcription.
