NSK-A – Amino Acid Reference Standards
This set contains a dry mixture of 12 isotopically labeled amino acids. The mixture contains the following amino acids: Alanine, Arginine, Aspartate, Citrulline, Glutamate, Glycine, Leucine, Methionine, Ornithine, Phenylalanine, Tyrosine, and Valine. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce a concentrated amino acid stock standard.
NSK-B – Free Carnitine and Acylcarnitine Reference Standards
This set contains a dry mixture of eight isotopically labeled free carnitine and acylcarnitines. The mixture contains the following: Carnitine (CN), Acetylcarnitine (C2), Propionylcarnitine (C3), Butyrylcarnitine (C4), Isovalerylcarnitine (C5), Octanoylcarnitine (C8), Myristoylcarnitine (C14), and Palmitoylcarnitine (C16). Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce a concentrated acylcarnitine stock standard.
NSK-S-CAH – Congenital Adrenal Hyperplasia (CAH) Reference Standards
NSK-S-CAH Congenital Adrenal Hyperplasia (CAH) Reference Standards is designed as a calibrator for use in screening, diagnosis and monitoring procedures for metabolic disorders. When used as directed, NSK-S-CAH provides a defined concentration solution of the following steroids: 17a-Hydroxyprogesterone, 4-Androstene-3,17-dione, 11-Deoxycortisol, 21-Deoxycortisol, and Cortisol. When combined with techniques such as tandem mass spectrometry (MS/MS), LC/MS, GC/MS, etc., the solution may be used as a calibrator to measure concentrations of steroids in plasma, blood spots, urine and other bodily fluids.
