Glycoprotein Q1 (U100), partial, human herpesvirus 6B, recombinant

Organism: Human herpesvirus 6B (strain Z29) (HHV-6 variant B) (Human B lymphotropic virus). Source: E.coli. Expression Region: 25-354aa. Protein Length: Partial. Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged. Target Protein Sequence: TVHRDAGTVE STPPPDDEDN YTAKYYDDSI YFNIYDGTNP TPRRRTLPEI ISKFSTSEMS RLGGLKAFVP VDYTPTTTLE DIEDLLNYAI CDDNSCGCLI ETEARSMFGD IIICVPLSAE SRGVRNLKSR IMPMGLSQIL SSGLGLHFSL LYGAFGSNYN SLAYMERLKP LTAMTAIAFC PMTSKLELRQ NYRLEKARSN LIVNIELLKI QNHGGQTIKT LTSFAIVRKD SDGQDWETCT RFASVSIEDI LRSKPAANGT CCPPRDVHHD RPTLQSSNSW TRTEYFEPWQ DVVDAYVPIN DNHCPNDSYV VFQTLQGHEW CSRLNKNDTK. 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: Plays a role in virus entry by participating in host receptor binding at the cell surface.
