Steroid Standards Mix Set S (40X)

Product Description

NSK-S-40X is a dried-down mix containing 5 stable isotope-labelled steroids. The standard concentrations are 40x that of NSK-S (e.g., cortisol is 4 μM instead of 100 nM). It’s designed for quantitative applications in MS/MS screening and can be used in combination with other NSK (and/or MSK) mixes for a broader panel of internal standards.

* Chemical purity (CP) is 98% or greater, unless otherwise specified. CPs are based upon HPLC and/or quantitative NMR analysis of the neat material. Each CP is accounted for in calculating the compound concentration for formulation. ^† Concentrations are achieved by reconstituting the dried down mix in 1 mL of solvent.
