LudgerSep R BPT solvent x10 Concentrate,R缓冲液
货号:LS-R-BPTX10 | 规格:50ml | 价格:¥0.00 | 品牌:Ludger
LudgerSep R缓冲液用于单糖的HPLC分析的丁胺/正磷酸/四氢呋喃溶剂 (BPT)。BPT 溶剂 x10 浓缩液。50ml,制成500ml溶剂。
The LudgerSep R BPTX Solvent was developed for the analysis of monosaccharides labeled with 2-AA using the LudgerTag Monosaccharide Labeling Kit

The LudgerSep R BPT Solvent is supplied at a 10x concentration of final as
50 mL of x10 BPT solvent in a rectangular HDPE bottle with a leak-proof cap.The R BPT Solvent contains volatile components so we always recommend making the solvent up on the day of intended use.

Preparation of the LudgerSep R BPT Solvent
1. Prepare De-gassed HPLC Grade Water (Optional)
Prepare de-gassed HPLC grade water if de-gassed solvents are required for your HPLC system.

De-gassing of solvents (e.g. by vacuum, sonication or helium sparging) is required for optimal performance of some HPLC systems. Note that the BPT solvent is semi-volatile so water should be de- gassed before adding the solvent concentrate.

2. Dilute the BPT X10 Solvent
For highly accurate and reproducible solvent preparation transfer BPT solvent to 500 mL sized glass volumetric flask, add water to make up to the 500 mL mark. Stopper the flask and invert to mix.

3. Use the BPT X10 Solvent
Use the BPT solvent for monosaccharide analysis according to the LudgerSep LS-UR2-2.1×50 UHPLC column guide or the LS-R2-4.6×150 HPLC column guide. HPLC solvent line filters should be used at all times.

Overview of the Monosaccharide Release and Labeling Procedue
The method for monosaccharide analysis is as follows:
1. Release of monosaccharides from the glycoprotein by mild acid hydrolysis.
2. Fluorescent labeling of released monosaccharides with 2-aminobenzoic acid (2-AA).
3. Relative quantitative analysis of 2AA-labeled monosaccharides by HPLC or UHPLC

The kit also contains the LudgerTag MonoMix, a monosaccharide standard containing glucosamine, galactosamine, galactose, mannose and fucose. Xylose is included for use as an internal standard.

There are two hydrolysis acids provided. 2 molar trifluoroacetic acid (2M TFA) and 6 molar hydrochloric acid (6M HCl). 2M TFA is good for releasing neutral monosaccharides but is less effective with the N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc) monosaccharides for which we recommend using 6M HCl. We recommend using these acids on separate replicates of your samples.
