Pisum sativum Lectin (PSA/PSL) - Ferritin
Price: Regular price $176.27
Product Description
Affinity purified Pisum sativum lectin or agglutinin (PSA) is a heterodimer that consists of four subunits. It has a carbohydrate specificity towards α-linked mannose-containing oligosaccharides. It’s hemagglutinating activity can be inhibited by glucose, mannose, and sucrose. It does not have a blood group specificity. The N-terminal sequence of the lectin has shown some degree of homology compared to lectins from other legume species. Pisum sativum lectin has also shown mitogenic effect toward murine splenocytes and could inhibit activity of HIV-1 reverse transcriptase. PSA is often used to differentiate virally transformed from normal cells. Calcium and manganese ions are required for activity.
Pisum sativum Lectin (PSA/PSL) is conjugated to ferritin, that has a molecular weight of 474,000 g/mol (all 24 subunits combined). Ferritin-conjugated lectins can be used to visualize localization of specific saccharide moieties and examine the distribution of plasma membrane glycoproteins. These conjugates can be viewed via electron microscopy.
