MS/MS Standards

Euriso-top has been providing amino acid and carnitine/acylcarnitine calibration standards for over 15 years. We offer both 10-vial sets or single vials of these products. CIL has custom kit capabilities. Please contact us with your custom kit needs.

NSK-A  – Amino Acid Reference Standards 

This set contains 10 vials of 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 the concentrations presented in the Standard Concentrations table. Mix well. This solution becomes the 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-B-G1 – Supplemental Acylcarnitine Reference Standards

This dry mixture contains five isotopically labeled acylcarnitines and is a supplemental mixture to the NSK-B mixture. The mixture contains:  Dodecanoylcarnitine (C12), Glutarylcarnitine (C5-DC), Hydroxyisovalerylcarnitine (C5-OH), Hydroxypalmitoylcarnitine, (C16-OH) and Octadecanoylcarnitine (C18).  Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce an acylcarnitine stock standard.

 

NSK-A-TS and NSK-B-TS

Tandem Mass Spectrometer (MS/MS) Tuning Standards, NSK-A-TS and NSK-B-TS, have been developed to complement quality assurance and quality control (QA/QC) procedures in the laboratory. The tuning standard will: ensure mass spec if operating at peak sensitivity, monitor sensitivity from the first sample to last and between runs, compare performance between multiple instruments and across laboratories,  and evaluate performance before and after instrument maintenance

 

NSK-T – Succinylacetone Reference Standards

The vial contains isotopically labeled succinylacetone (SUAC) used for lab developed tests involving Tyrosinemia Type 1. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce a concentrated succinylacetone 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.

 

NSK-A-US – Amino Acid Unlabeled Reference Standards 

This vial contains a dry mixture of 12 amino acids. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce the concentrations presented in the Standard Concentrations table. Mix well. This solution becomes the concentrated amino acid stock standard.

 

NSK-B-US – Free Carnitine and Acylcarnitine Unlabeled Reference Standards

This vial contains a dry mixture of eight free carnitine and acylcarnitines. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce the concentrations presented in the Standard Concentrations table. Mix well. This solution becomes the concentrated acylcarnitine stock standard.
