Dilute the role of human menopause gonadotropin to understand

  HMG is produced from a sterile preparation of placental glucoprotein urine of post-menopausal women.

  The hMG is purified by proprietary chromatographic techniques.

  Physical Appearance:

  Sterile Filtered White lyophilized (freeze-dried) powder.

  Formulation:

  Lyophilized from a concentrated (1 mg/ml) solution in water containing no additives.

  Solubility:

  It is recommended to reconstitute the lyophilized hMG in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

  Stability:

  Lyophilized hMG although stable at room temperature for 3 weeks, should be stored desiccated below -18 C. Upon reconstitution hMG should be stored at 4 C between 2-7 days and for future use below -18 C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

  Please avoid freeze-thaw cycles.

  Purity:

  Greater than 98.0% as determined by:

  (a) Analysis by RP-HPLC.

  (b) Anion-exchange FPLC.

  (c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
