Native Porcine Gastrin II Reference Standard

• Cat.No.: Gastrin II-22PRS

Specification

• Species: Porcine
• Source: Porcine
• Tag: Non
• Tag: Non
• Form: Freeze-dried powder
• Stability: Reference Materials should be stored on receipt as indicated on the label. In addition, once reconstituted, diluted or aliquoted, users should determine the stability of the material according to their own method of preparation, storage and use.
• Usage: Calibrant for porcine gastrin II assays
• Storage: Store at -20°C or below in the dark.
• contents: Each ampoule contains approximately:
  Highly-purified porcine gastrin II 10μg
  Sucrose 5mg
  The residue of approx. 0.1 M Sorensen''s buffer
• Shipping: Because of the inherent stability of lyophilized material,may ship these materials at ambient temperature.
• UNITAGE: Each ampoule of the Standard contains 10 units (by definition)
• USE OF MATERIAL: No attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution.
  For all practical purposes each ampoule contains the same amount of the same materials. Dissolve the total contents in a known amount of suitable buffer solution with carrier protein (free of peptidase), where extensive dilution is required, to minimise loss by surface adsorption.
  For economy of use it is recommended that the solution be subdivided into several small containers, which are frozen rapidly to below –40°C and then stored below –40°C in the dark. Repeated freezing and thawing should be avoided.
