Sambucus nigra lectin (SNA, EBL), Fluorescein labeled

Product Details

Sambucus Nigra Lectin (SNA, EBL), Fluorescein, 2 mg, isolated from elderberry bark, binds preferentially to sialic acid attached to terminal galactose in alpha-2,6 and to a lesser degree, alpha-2,3 linkage. Binding is also inhibited to some extent by lactose or galactose. This lectin does not appear to bind sialic acid linked to N-acetylgalactosamine. SNA has been reported to inhibit cell-free protein synthesis. This product has an appropriate number of fluorochromes to provide the optimum staining characteristics and is supplied essentially free of unconjugated fluorochromes. The excitation maximum is at 495 nm, and the emission maximum is at 515 nm. Accompanying each fluorescent lectin is an analysis data sheet summarizing the results of quality control tests and providing pertinent information on the product. Supplied as solution preserved with sodium azide. Elution: 500 mM lactose in buffered saline followed by 500 mM lactose in acetic acid.
