 Conjugate Details

Sigma has the largest selection of lectins and lectin conjugates available for the life scientist. Over 100 products from over 35 naturaLsources. Conjugates include:

  • Agarose
  • FITC
  • Peroxidase
  • Biotin
  • Gold

Many lectins are available as conjugates. Conjugation does not alter the specificity of the lectin. The degree of conjugation is expressed as 1) a mole dye per mole lectin basis 2) a unit enzyme activity per mg protein or 3) a mg protein per mLpacked geLbasis. For colloidaLgold conjugates, the activity of the lectin is determined by a dot blot assay using an appropriate glycoprotein. Agglutination activity is expressed in microgram per mLand is determined from seriaLdilution studies of a 1 mg per mLsolution. This activity is the lowest concentration of lectin to agglutinate a 2% suspension of appropriate erythrocytes after 1 hour incubation at 25 °C.
