| Description | Leptin Human produced syntheticaly contains 35 amino acids （22-56 a.a.） having a molecular mass of 3950.6 Dalton. |
| Physical Appearance | Sterile Filtered White lyophilized （freeze-dried） powder. |
| Formulation | The protein was lyophilized from a concentrated （1mg/ml） solution with no additives. |
| Solubility | The lyophilized Leptin is very soluble in water and most aqueous buffers below and above the isoelectric point. |
| Stability | Lyophilized Leptin although stable at room temperature, should be stored desiccated below -20°C. Reconstituted Leptin is best stored refrigerated at 4°C. |
| Purity | Greater than 95.0% as determined by RP-HPLC. |
| Amino acid sequence | Val-Pro-Ile-Gln-Lys-Val-Gln-Asp-Asp-Thr-Lys-Thr-Leu-Ile-Lys-Thr-Ile-Val-Thr-Arg-Ile-Asn-Asp-Ile-Ser-His-Thr-Gln-Ser-Val-Ser-Ser-Lys-Gln-Lys. |
