Quantitative Standards

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.

2-AB BioQuant Chitotriose


The 2-AB labeled chitotriose standard is a fluorescently tagged linear tri-N-acetylglucosamine quantitative standard. The standard has been accurately dispensed from a bulk solution the concentration of which has been determined by quantitative NMR.

The bulk chitotriose concentration value was used to determine the amount of sample to be dispensed per vial to obtain 100 pmol of chitotriose per vial.  Once dispensed the amount of chitotriose per vial is determined by monosaccharide analysis.

The dispensing error is predicted to be than less 5%.

Amount: 100 pmol by qNMR
