General description
Pyridoxal 5′-phosphate (PLP) is the major circulating form of vitamin B6 and the most common direct measure of this vitamin in serum or plasma. A unit of the vitamin B6 standard reference material (SRM) 3950 consists of two stoppered vials of frozen human serum, one vial each at two different concentration levels. Each vial contains 1.0 mL of human serum.

Application
Vitamin B6 in frozen human serum standard reference material (SRM) 3950 is intended primarily for use in evaluating the accuracy of procedures for the determination of the vitamin B6 metabolite pyridoxal 5′-phosphate (PLP) in human serum. It is also intended for use in validating working or secondary reference materials.
Features and Benefits
The use of this material will provide confidence in the assignment of values to the in-house assay calibrators.
Preparation Note
- SRM 3950 is provided as a frozen serum that should be allowed to thaw at room temperature (20 °C to 25 °C) under subdued light.
- After the material is thawed, it should be used immediately.
- The contents of the vial should then be gently mixed prior to the removal of a test portion for analysis.
- Precautions should be taken to expose serum only under subdued lighting conditions.
Other Notes
- SRM 3950 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
