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.

Preparation Note

  • 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.

Other Notes

  • SRM 3949 is intended for research use.
  • Details on expiration, storage, safety, usage, and source are provided in the NIST certificate
  • Information on biomaterials, disposal, and transport is available in the SDS

One predominant and bioactive folate vitamer circulating in the blood is 5-methyltetrahydrofolate (5-Me-THF). In this study, a method for the accurate determination of 5-Me-THF in human plasma samples of various volumes was established using isotope dilution ultra-high performance liquid chromatography-mass
