Product Description
Datura stramonium lectin (DSL) binds to (beta-1,4) linked N-acetylglucosamine oligomers, preferring chitobiose or chitotriose over single N-acetylglucosamine residues. DSL also binds well to N-acetyllactosamine and oligomers containing repeating N-acetyllactosamine sequences. This lectin binds well in the acidic pH range, but its affinity decreases above pH 8.0. The lectin may be used to stain tissue sections. Biotium offers DSL conjugated to biotin and a selection of 6 bright and photostable CF® Dyes.
- Binds to (beta-1,4) linked N-acetylglucosamine oligomers
- Suitable for immunofluorescence staining in tissue sections
- Choice of 6 CF® Dyes or biotin
- Supplied at 1 mg/mL in 10 mM HEPES pH 7.5, 0.15 M NaCl, 0.08% sodium azide, 0.1 mM CaCl2
Note: CF® Dye DSL conjugates are formulated with sodium azide and are not suitable for use in vivo or live cell culture
Find the Right Stain for Your Application
DSL and other lectins are carbohydrate binding proteins that recognize specific sugar moieties on glycoproteins. The presence and distribution of these targets vary between cell types and tissues. As a result, other cell surface stains or other lectin conjugates, Ulex europaeus agglutinin I (UEA I), Lycopersicon esculentum (Tomato), Phaseolus vulgaris leucoagglutinin (PHA-L), Wheat Germ Agglutinin (WGA) conjugates, Concanavalin A (Con A) and Arachis hypogaea (PNA) conjugates, may produce better surface staining and may be more appropriate for your cell type. Lectin conjugates can be used to selectively stain the cell surface of live cells, and withstand fixation and permeabilization. When cells are fixed and permeabilized before staining, fluorescent lectins stain both cell surface and organelles in the secretory pathway. Lectins may be toxic or stimulatory to live cells depending on cell type. To find the right stain for your application, see our Membrane & Cell Surface Stains Comparison. See our Cellular Stains Table for more information on how our dyes stain various organisms.
