Erythrina Cristagalli Lectin (ECL, ECA), Biotinylated, 5 mg. Features: Matrix is heat-stable, crosslinked 4% agarose beads with a molecular exlusion of about 2x107 daltons; Bead diameter ranges in size from 45–165 microns; Matrix is stable in solutions at pH 3–11 as well as many organic solvents; Immobilized lectins are prepared using affinity-purified lectins; Covalent attachment preserves lectin activity and minimizes conformational changes that might result in non-specific or hydrophobic interactions; Hydrophilic spacer arm is inserted between the lectin and the matrix; Conjugated proteins are not leached off the beads by Tris or other routinely used buffers; No residual charges present after conjugation, minimizing non-specific binding to the matrix. Product supplied as a 1:1 suspension in buffer (2 mg lectin/ml gel). Inhibiting/Eluting Sugar: 100 mM L-fucose or Glycoprotein Eluting Solution (Cat. No. ES-3100).
