Abstract
CRM-DTX2-b is a certified calibration solution designed for analytical method development and accurate quantitation of DTX2. The concentration of CRM DTX2-b makes it suitable for preparing a dilution series for calibration of liquid chromatography (LC) and liquid chromatography-mass spectrometry (LC-MS) instrumentation, as well as for spiking shellfish control samples for recovery experiments.
