NSK-A-CE and NSK-B-CE Amino Acid and Free Carnitine/Acylcarnitine Reference Standards
- NSK-A-CE and NSK-B-CE Amino Acid and Free Carnitine/Acylcarnitine Reference Standards
The NSK-B-CE reference standard is composed of a dry mixture (packaged as 10 vials per box) of eight stable isotope-labeled standards (free carnitine and eight acylcarnitines). When used as directed (see instructions in product flyer), this product provides a solution to quantitatively measure these target analytes in a range of neonate biosamples (e.g., dried blood spot, urine) using a variety of MS-based techniques. These screens can be used toward the detection of organic acidemias (e.g., methylmalonic acidemia, propionic acidemia) and fatty acid oxidation disorders (e.g., carnitine uptake defect, medium-chain and very long-chain acyl-CoA dehydrogenase deficiencies).
For sale in European Economic Area (EEA) – EU and EFTA – only.
For professional use only.
In the US, CIL products are labeled “For research use only. Not for use in diagnostic procedures.”

Frequently Asked Questions
What is the difference between NSK-B and NSK-B-CE?
The regulated NSK-B-CE product is designed for use as a calibrator in screening, diagnosis, and monitoring procedures of organic acidemias and fatty acid oxidation disorders. This is a CE-marked IVD medical device (manufactured according to ISO 13485:2016) that is available only in the European Economic Area (EU and EFTA). The nonregulated NSK-B product, in contrast, is not designed for specific metabolic assessment procedures and is globally available for research applications.
What QC tests are performed on NSK-B-CE?
The analyte concentrations of NSK-B-CE are based on HPLC analysis of the reconstituted product against a traceable standard. The mean and standard deviations of the analyzed measurements, together with the target and prepared concentrations, are reported in the product CoAs. Isotopic enrichments (≥98%, via LC-MS) and chemical purity (1H NMR) are based on tests of the starting materials.
What is the recommended protocol for reconstituting this isotope-labeled mix?
The guidelines for reconstitution are detailed in the product flyer.
What is the storage and shelf life of this isotope-labeled mix?
The details of storage and shelf life are tabulated in the product flyer. This reflects both before and after mix reconstitution.
