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
