Recombinant BK polyomavirus Small t antigen

• CAS Number: 9000-83-3
• UniProt: P15000
• Expression Region: 1-172aa
• Organism: BK polyomavirus (strain AS) (BKPyV)
• Target Sequence: MDKVLNREESMELMDLLGLERAAWGNLPLMRKAYLKKCKEFHPDKGGDEDKMKRMNTLYKKMEQDVKVAHQPDFGTWNSSEVCADFPLCPDTLYCKEWPICSKKPSVHCPCMLCQLRLRHLNRKFLRKEPLVWIDCYCIDCFTQWFGLDLTEETLQWWVQIIGETPFRDLKL
• Tag: N-terminal 10xHis-tagged and C-terminal Myc-tagged
• Source: E.coli
• Field of Research: Others
• Assay Type: Developed Protein
• Relevance: Promotes efficient viral genome replication by accelerating both G1 and S phase progression of the cell cycle. Inhibits host PP2A by binding to the A subunit, thereby displacing lower affinity regulatory B subunit. Inactivation of PP2A in turn results in the transactivation of cyclin A and cyclin D1 promoters. Late during the infection cycle, ST may induce dephosphorylation of host MTOR, leading to the inhibition of cap-dependent translation. May establish and maintain high levels of viral genomes during persistent infection in cell culture.
• Purity: Greater than 90% as determined by SDS-PAGE.
• Activity: Not Test
• Length: Full Length
• Form: Liquid or Lyophilized powder
• Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
• Reconstitution: 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 -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Storage Conditions: 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 -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
