The amount of standard dispensed per vial is determined by quantitative Nuclear Magnetic Resonance (qNMR) of the bulk stock. Once dispensed the amount per vial is determined by monosaccharide analysis.
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.
This quantitative glycopeptide standard was developed for use during the sialic acid or monosaccharide release and labeling process. This will enable you to check the efficiency of glycan release, labeling, and recovery.
Purity: >90% as determined by UHPLC
Monoisotopic mass: 2865.1763 [M+H]+
Amount: 10 micrograms
Part number: BQ-GPEP-A2G2S2-10U
The chitotriose quantatative standard is a linear tri-N-acetylglucosamine glycan.
Quantity determined by quantitative Nuclear Magnetic Resonance (qNMR).
Can be used as an internal or external standard, spiked directly into your glycan sample or run in parallel.
Amount: 5 ± 0.30 nmol by qNMR
Part Number: BQ-CHITOTRIOSE-01
The BioQuant quantitative Man8 glycan is a purified and quantified glycan standard which can be used as an internal standard and positive control for quantitative analysis (e.g. monosaccharide analysis).
Glycan Purity determined as > 90% by UHPLC
Monoisotopic mass: 1721.6 [M+H]+
Part number: BQ-CN-MAN8-10U
