Native Human Factor VIIa Reference Standard

• Cat.No.: FVIIa-16HRS

Specification

• Species: Human
• Source: Human
• Tag: Non
• Tag: Non
• Form: Freeze dried powder
• Stability: Accelerated degradation studies have indicated that this material is suitably stable, when stored at -20 °C or below, for the assigned values to remain valid until the material is withdrawn or replaced. These studies have also shown that the material is suitably stable for shipment at ambient temperature without any effect on the assigned values.
• Usage: The standard is primarily intended for the relative potency estimation of therapeutic concentrates of activated factor VII.
• Storage: Unopened ampoules should be stored in the dark at -20 °C or below.
• Shipping: Because of the inherent stability of lyophilized material, may ship these materials at ambient temperature.
• UNITAGE: The overall mean potency assigned to each ampoule of the 2nd IS is 656 IU.
• USE OF MATERIAL: No attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution.Reconstitute the total contents of each ampoule of the standard at room temperature with 1.0ml distilled water using gentle shaking. Transfer the solution to a plastic tube. Assays should be carried out as soon as possible after reconstitution. Studies have shown that the reconstituted standard is stable for 4 hours when stored in a plastic tube on melting ice. It is not recommended to freeze aliquots after reconstitution for subsequent use.
