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.
