Quantitative glycan standards
Quantitative Glycan Standards
Part of Ludger’s range of System Suitability Standards and Controls, our BioQuant range has been designed for glycan quantitation.
Purity of BioQuant standards is determined as > 90% by UHPLC. Correct mass identity is assessed by MALDI mass spectrometry. The exact amount of material/concentration is determined by quantitative NMR (qNMR) and quantitative monosaccharide analysis (MA). Quantity values by qNMR and MA agree within 90-110%. MA is traceable to internationally accepted references from USP and dispensed using NIST traceable labware. qNMR is traceable to a NIST SRM traceable Certified Reference Material which has been analysed to the ISO 17025 standard.
A detailed Certificate of Analysis is given for each BioQuant standard which contains comprehensive documentation, lot-specific values, expiration date and storage information.
