## Abstract A practical and convenient method for discriminating between the presence and the absence of sialic acid in carbohydrate chains of glycoproteins was devised using paramagnetic beads and two lectins, __Sambucus sieboldiana__ lectin (SSA) and __Ricinus communis__ agglutinin (RCA120). The

✦ Synopsis
The quantitative determination of glycoproteins and lectins by laser nephelometry is based on the fact that these two compounds form a complex comparable to the antigenantibody precipitate. Due to the high sensitivity and reliability of this technique less than 25 pmol of glycoprotein or 4.5 pmol of lectin can be determined, thus providing a suitable method (a) to investigate the specificity of different lectins for certain carbohydrate residues, (b) to study the mode of interaction, and (c) to explore mammalian tissue for still-unknown lectin-like substances.
