What equipment is needed for this method?

Basic laboratory equipment such as a kitchen blender and centrifuge is required to perform this method.

Nous décrivons une méthode simple et rapide pour la préparation et l’analyse des N- glycans de différents cultivars de radis (Raphanus sativus).

Cette méthode peut aider à répondre à des questions dans le domaine de la glycoscience végétale, telles que la façon dont les N-glycanes d’origine végétale peuvent être rapidement analysés et caractérisés. Le principal avantage de cette technique est qu’elle ne nécessite aucun changement de tampon entre la libération enzymatique de N-glycanes et les réactions de dérivatisation avec le 2-aminobenzamide. La démonstration de la procédure sera Mlle Ya-Min Du et Mlle Shen-Li Zhen ; deux étudiants diplômés du Centre de recherche en bio-ingénierie de la glycomique et des glycanes de l’Université agricole de Nanjing.

Pour commencer à isoler les protéines, utilisez un mixeur de cuisine pour homogénéiser environ 100 grammes de radis frais pendant dix minutes. Transférez la boue obtenue dans un tube à centrifuger de 50 millilitres. Centrifuger à 14 000 fois la gravité à quatre degrés Celsius pendant 20 minutes pour éliminer le matériau insoluble.
