Example of standard curve obtained with the Kynurenine ELISA Kit. In this competitive ELISA, optical density is invertly correlated with Kynurenine levels. Only serves as example - do not use for calculation.
DatasheetMSDSProtocol
The L-Kynurenine ELISA is an easy-to-use assay tailored for the quantification of Kynurenine across large series of samples. Intended for research use only, the KYN ELISA features a lower limit of detection at 45.7ng/ml and a minimal sample volume of 20µl, thus allowing longitudinal studies in mice.
