Recombinant Exendin-4 Protein, a monomer containing 39 amino acid residues, has a predicted molecular mass of approximately 4.2 kDa.

> 98% by SDS-PAGE gel and HPLC analyses.

Less than 0.01 EU/μg of rExendin-4 as determined by LAL test.

1. Regulates Glucose levels rapidly; 2. Reduces Insulin resistance; 3. Reduces Glucagon; 4. Reduces HbA1c; 5. Stimulates beta cell growth which stimulates insulin production.

Lyophilized from a 0.22 μm filtered solution in PBS. See CoA for details.

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. Reconstitute in sterile distilled water to a concentration of 0.1-1.0 mg/mL. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.

Please use a manual defrost freezer and avoid repeated freeze-thaw cycles.

• Lyophilized protein should be stored at ≤ -20°C, stable for 12 months after receipt.
• Reconstituted protein solution can be stored at 2-8°C for 1 month.
• Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
