Cone-rod homeobox protein (CRX), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-299aa. Protein Length: Full Length. Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged. Target Protein Sequence: MMAYMNPGPH YSVNALALSG PSVDLMHQAV PYPSAPRKQR RERTTFTRSQ LEELEALFAK TQYPDVYARE EVALKINLPE SRVQVWFKNR RAKCRQQRQQ QKQQQQPPGG QAKARPAKRK AGTSPRPSTD VCPDPLGISD SYSPPLPGPS GSPTTAVATV SIWSPASESP LPEAQRAGLV ASGPSLTSAP YAMTYAPASA FCSSPSAYGS PSSYFSGLDP YLSPMVPQLG GPALSPLSGP SVGPSLAQSP TSLSGQSYGA YSPVDSLEFK DPTGTWKFTY NPMDPLDYKD QSAWKFQIL. 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: Transcription factor that binds and transactivates the sequence 5'-TAATC[CA]-3' which is found upstream of several photoreceptor-specific genes, including the opsin genes. Acts synergistically with other transcription factors, such as NRL, RORB and RAX, to regulate photoreceptor cell-specific gene transcription. Essential for the maintenance of mammalian photoreceptors. Reference: "Mutations in the cone-rod homeobox gene are associated with the cone-rod dystrophy photoreceptor degeneration."
