Epstein-Barr nuclear antigen 1 (EBNA1), partial, Biotinylated, Epstein-Barr virus, recombinant

Organism: Epstein-Barr virus (strain B95-8) (HHV-4) (Human herpesvirus 4). Source: E.coli. Expression Region: 458-641aa. Protein Length: Partial. Tag Info: N-terminal MBP-tagged and C-terminal 6xHis-Avi-tagged. Target Protein Sequence: RRKKGGWFGK HRGQGGSNPK FENIAEGLRA LLARSHVERT TDEGTWVAGV FVYGGSKTSL YNLRRGTALA IPQCRLTPLS RLPFGMAPGP GPQPGPLRES IVCYFMVFLQ THIFAEVLKD AIKDLVMTKP APTCNIRVTV CSFDDGVDLP PWFPPMVEGA AAEGDDGDDG DEGGDGDEGE EGQE. Purity: Greater than 85% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. 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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: 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 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Cell surface receptor for SEMA4C, SEMA4D and SEMA4G that plays an important role in cell-cell signaling. Plays a role in glutamatergic synapse development and is required for SEMA4A-mediated excitatory synapse development. Binding to class 4 semaphorins promotes downstream activation of RHOA and phosphorylation of ERBB2 at 'Tyr-1248'. Required for normal differentiation and migration of neuronal cells during brain corticogenesis and for normal embryonic brain development. Regulates the migration of cerebellar granule cells in the developing brain. Plays a role in RHOA activation and subsequent changes of the actin cytoskeleton. Plays a role in axon guidance, invasive growth and cell migration. May modulate the activity of RAC1 and CDC42.
