FITC Conjugated Vicia villosa Lectin (Bushy Vetch) -VVA-

Summary

Glycans are the results of the coordinated actions of glycosyltransferases accountable for particular sugar additions. Glycans current on proteins can affect protein stability, transport, operate, and recognition, and thus can have profound results on cell–cell interactions, adhesion, and signaling occasions occurring throughout eukaryotic improvement. Lectin staining gives a great tool to detect the spatial distribution of particular glycans in creating tissues in situ. Right here we describe a technique to detect various glycans current in creating Drosophila tissues and organs utilizing fluorescently labeled lectins.

Key phrases: Glycosylation, Glycans, Lectins, Confocal microscopy, Drosophila, Growth

1 Introduction

Glycosyltransferases are accountable for the formation of particular glycan buildings that may have various organic results. Lectins are sugar-binding proteins which have been used to detect quite a lot of glycan buildings current throughout eukaryotic improvement [1, 2]. In an effort to find out the spatial distribution of glycans throughout Drosophila improvement, we’ve stained Drosophila embryos and tissues with fluorescently labeled lectins and carried out confocal microscopy [3]. This technique is appropriate with whole-mount staining, permitting one to picture glycan expression in a 3D embryo or tissue at particular developmental levels.
