Features: Matrix is heat stable, cross-linked 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 nonspecific 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. This minimizes non-specific binding to the matrix. Product supplied as a 1:1 suspension in buffer 3 mg lectin/ml gel Inhibiting/Eluting Sugar: 200 mM lactose or Glycoprotein Eluting Solution (ES-1100)
