Recombinant Human HSP90AA1 protein, His-tagged

Specification :
| Description : The protein encoded by this gene is an inducible molecular chaperone that functions as a homodimer. The encoded protein aids in the proper folding of specific target proteins by use of an ATPase activity that is modulated by co-chaperones. Two transcript variants encoding different isoforms have been found for this gene. | Source : E. coli | Species : Human | Tag : His-tagged | Form : Liquid or Lyophilized powder | Molecular Mass : 11.2 kDa | Protein length : 233-291aa | AA Sequence : DEAEEKEDKEEEKEKEEKESEDKPE IEDVGSDEEEEKKDGDKKKKKKIKE KYIDQEELN | Purity : Greater than 85% as determined by SDS-PAGE. | Notes : Repeated freezing and thawing is not recommended. Store working aliquots at 4 centigrade for up to one week. | Storage : Store at -20 centigrade/-80 centigrade upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles. | Expiry : 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 centigrade/-80 centigrade. The shelf life of lyophilized form is 12 months at -20 centigrade/-80 centigrade. | Storage 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 centigrade/-80 centigrade. Our default final concentration of glycerol is 50%.
