Product Information

Peptide Sequence	RSIPIHQDNLKNLVKLQADTIIHRIKEHNEKLKLSPKILIGDSELYPEVPADKPIQGLGSIVDTLTTFQKILQTLPKGHVSQLHNDMSTLLEYFKDRMTFMRCTLKEPANGKSLDTFIEKNATHHITFGYMALDRLKQFMQKLIDNLDQLKSC (21-173 aa encoded by EU794002)
Activity	Not tested.
Endotoxin Level	Please contact the lab for more information. Note：Remove endotoxin and sterilization is required for cell assay.
Purity	85%, by SDS-PAGE with Coomassie Brilliant Blue staining.
Formulation	The purified protein was Lyophilized from sterile PBS (58mM Na2HPO4,17mM NaH2PO4, 68mM NaCl, pH7.4). 5 % trehalose and 5 % mannitol are added as protectant before lyophilization. The elution buffer contain 300mM imidazole.

Reconstitution and Storage

Reconstitution	Reconstitute at 0.25 µg/μl in 200 μl sterile water for short-term storage. After reconstitution with sterile water, if glycerol has no effect on subsequent experiments, it is recommended to add an equal volume of glycerol for long-term storage (see Stability and Storage for more details). If a different concentration is needed for your purposes please adjust the reconstitution volume as required (please note: the ion concentration of the final solution will vary according to the volume used). Note: Centrifuge vial before opening. When reconstituting, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution.
Shipping	The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature (see below).
Stability and Storage	Store for up to 12 months at -20°C to -80°C as lyophilized powder.
Storage of Reconstituted Protein	Short-term storage: Store at 2-8°C for (1-2 weeks). Long-term storage: Aliquot and store at -20°C to -80°C for up to 3 months, reconstitution with sterile water and addition of an equal volume of glycerol. Avoid repeat freeze-thaw cycles.
