Carboxypeptidase A6 (CPA6), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 130-437aa. Protein Length: Full Length of Mature Protein. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: SLSGYNYEVY HSLEEIQNWM HHLNKTHSGL IHMFSIGRSY EGRSLFILKL GRRSRLKRAV WIDCGIHARE WIGPAFCQWF VKEALLTYKS DPAMRKMLNH LYFYIMPVFN VDGYHFSWTN DRFWRKTRSR NSRFRCRGVD ANRNWKVKWC DEGASMHPCD DTYCGPFPES EPEVKAVANF LRKHRKHIRA YLSFHAYAQM LLYPYSYKYA TIPNFRCVES AAYKAVNALQ SVYGVRYRYG PASTTLYVSS GSSMDWAYKN GIPYAFAFEL RDTGYFGFLL PEMLIKPTCT ETMLAVKNIT MHLLKKCP. Purity: Greater than 90% 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: May be involved in the proteolytic inactivation of enkephalins and neurotensin in some brain areas. May convert inactive angiotensin I into the biologically active angiotensin II.
