Application

Folate Vitamers standard reference material (SRM) is intended for use in validating methods for determining folate vitamers in human serum, and for qualifying the in-house control materials analyzed using those methods.

Notes préparatoires

  • SRM 3949 is provided as a set of three vials of frozen serum that should be allowed to thaw at room temperature for at least 30 min under subdued light.
  • The contents of a vial should then be gently mixed prior to the removal of a test portion for analysis.
  • Precautions should be taken to avoid exposure to strong ultraviolet (UV) light and direct sunlight.

Autres remarques
