Peptide Sequence |
The sequence of the first five N - terminal amino acids was determined and was found to be Ala - Val - Pro - Ile - Arg. |
Product Format |
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3. Physical appearance: Sterile Filtered White lyophilized (freeze-dried) powder. |
Description of Target |
Recombinant Bovine Leptin |
Reconstitution and Storage |
Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution Leptin should be stored at 4C between 2-7 days and for future use below -18C. For long term storage it is recommended to add a carrier protein (0. 1% HSA or BSA). Please prevent freeze-thaw cycles. |

Additional Information |
Solubility: It is recommended to reconstitute the lyophilized Leptin in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions. |
Additional Information |
Biological Activity: Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. |
Additional Information |
Protein Content: Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.19 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENEcomputer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC,using calibrated solution of Leptin Bovine as a Reference Standard.
