Description | Recombinant human LEP protein is produced by our E. coli expression system and the target gene encoding Val22-Cys167 is expressed. |
Tested applications | ELISA, MS, SDS-PAGE, WB |
Reactivity | Human |
Form/Appearance | Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4. |
Purity | Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. |

Source | E. coli |
Endotoxins | Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test. |
Storage | Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months. |
Buffer/Preservatives | Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4. |
Alternative names | OB; OBS; Leptin; Obese protein; Obesity factor Read more... |
Note | For research use only |
Application notes | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
Expiration Date | 6 months from date of receipt. |
The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining. | |
The protein has a predicted molecular mass of 94.3 kDa after removal of the signal peptide. The apparent molecular mass of LEPR-His is approximately 130-250 kDa due to glycosylation. | |
Mammalian |
The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. | |
The protein has a predicted molecular mass of 42.2 kDa after removal of the signal peptide. The apparent molecular mass of LEP-hFc is approximately 35-55 kDa due to glycosylation. | |
