Solanum Tuberosum (Potato) Lectin (STL, PL), Unconjugated

This lectin binds oligomers of N-acetylglucosamine and some bacterial cell wall oligosaccharides containing N-acetylglucosamine and N-acetylmuramic acid. Although the carbohydrate binding specificity is similar to wheat germ agglutinin and Datura stramonium lectin, several differences have been reported for potato lectin.

Technical Information

Solanum tuberosum lectin consists of two identical 50 kDa subunits. The subunits can dissociate in solution to produce a monomeric form of the lectin which does not agglutinate cells. This lectin binds oligomers of N-acetylglucosamine and some bacterial cell wall oligosaccharides containing N-acetylglucosamine and N-acetylmuramic acid. Although the carbohydrate binding specificity is similar to wheat germ agglutinin and Datura stramonium lectin, several differences have been reported for potato lectin.
