| Reconstitution | It is recommended to reconstitute the lyophilized recombinant mouse pegylated leptin in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions. |

| Description | Mono-pegylated (with 20 kDa PEG)recombinant mouse leptin is an one polypeptide chain containing 146 amino, an additional Ala at N-terminus and one molecule of PEG 20 kDa at its N-terminus, having an expected molecular mass of ~ 35.6 kDa as determined by MS. However due to enlarged hydrodymanic volume recombinant mouse pegylated leptin runs on the SGS-Page as 48 kDa protein and in gel-filtration on Superdex 200 as over 100 kDa protein. Recombinant mouse pegylated leptin half-life in circulation after SC injection was over 20 hours. Recombinant mouse leptin was purified by proprietary chromatographic techniques according to Salomon et al (2006) Protein Expression and Purification 47, 128–136 and then pegylated. |
