Anti-Ricin A Chain Antibody, clone RAC18

29.89 kDa calculated.

Ricin is a dimeric toxin derived from Ricinus communis (Caster bean). It is composed of a sugar-binding subunit (B chain) that attached to cell surface receptors and facilitate the entry of toxin into the target cell and a second subunit (A chain), whcih has glycosidase activity that inactivates ribosomes by depurinating a single adenosine residue from an exposed loop of the 28S ribosomal RNA. This leads to inhibition of protein synthesis in cells. The toxic effects of Ricin are attributed to the A chain. Clone RAC18 displays high avidity for intact ricin and inhibits its activity without affecting binding of ricin to cells. Immunization with RAC18 is shown to offer significant protection against ricin toxicity. (Ref.: Maddaloni, M., et al. (2004). J. Immunol. 172; 6221-6228).
