Pisum sativum agglutinin is nearly identical in structure and carbohydrate specificity to Lens culinaris agglutinin. PSA has four subunits, two of approximately 17,000D and two of about 6,000D. Isoelectric focusing has revealed two isolectins with isoelectric points of pH 5.9 and pH 7.0. The lectin has specificity toward a-linked mannose-containing oligosaccharides, with an N-acetylchitobiose-linked a-fucose residue included in the receptor sequence. Calcium and manganese ions are required for activity. PSA has been used to fractionate cells, to isolate glycoproteins and glycopeptides, to distinguish between normal and virally transformed cells, as a T-cell mitogen, and as an inhibitor of allograft rejection.

Applications:
Suitable for use in ELISA. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Inhibiting/Eluting Sugar:
200mM a-methyl mannoside/200mM a-methyl glucoside mixture
