Conjugate Details:

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

• Agarose • FITC • Peroxidase • Biotin • TRITC • 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 ml packed gel basis. For colloidal gold conjugates, the activity of the lectin is determined by a dot blot assay using an appropriate glycoprotein. Agglutination activity is expressed in microgram per ml and is determined from serial dilution studies of a 1 mg per ml solution. This activity is the lowest concentration of lectin to agglutinate a 2% suspension of appropriate erythrocytes after 1 hour incubation at 25 0C.
