The Leptin is purified by proprietary chromatographic techniques.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.
Amino acid sequence
1. UV spectroscopy at 280 nm using the absorbency value of 0.201 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of Leptin rat as a Reference Standard.
