Binding Site Human IgM Kit (for SPAPLUS), REF: NK012.S The device consists of reaction buffer, sheep anti-IgM antiserum, six calibrators and two controls. The calibrators and controls are based on stabilized human serum. All components contain sodium azide as a preservative and are provided in ready-to-use liquid format.
After running the calibration curve, the recovery of the IgM kit control results decrease demonstrating a reduction in accuracy within the same day; control results may be out of range one day after running the assay calibration curve. Samples have been shown to be similarly affected.
