Sambucus Nigra Lectin (SNA, EBL) Conjugates

SNA lectin binds to sialic acid attached to terminal galactose. SNA lectin is a carbohydrate-binding protein that can induce apoptosis in insect cells and cultured mammalian cell cancer cells. Biotium offers SNA lectin conjugated to biotin and a selection of 6 bright and photostable CF® Dyes.

Product Description

Sambucus nigra lectin, also known as elderberry bark lectin (EBL) and Sambucus nigra agglutinin (SNA), belongs to the group of type 2 ribosome-inactivating proteins. It is composed of an A-chain with enzymatic activity and a B-chain with carbohydrate-binding activity, and has a combined molecular weight of ~140,000 Da. Sambucus Nigra Lectin (SNA, EBL) CF® Dye Conjugates bind to sialic acid attached to terminal galactose in α-2,6 and to a lesser degree, α-2,3 linkage. SNA can induce apoptosis in insect cells and cultured mammalian cell cancer cells. This effect depends on the carbohydrate binding of the B-chain.

  • Binds to sialic acid linked to terminal galactose
  • 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: SNA CF® Dye 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

SNA 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, Datura stramonium lectin (DSL), 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.

Superior CF® Dyes

SNA lectin is available conjugated to biotin and a selection of bright and photostable CF® Dyes. Biotium’s next-generation CF® Dyes were designed to be highly water-soluble with advantages in brightness and photostability compared to other fluorescent dyes. Learn more about CF® Dyes.
