Ricin (RTA subunit), clone MMA

Ricin is a protein found in castor bean (Ricinus communis) acting as protein synthesis inhibitor. It is a toxin involved in plant defence. A chain of ricin can inactivate few thousands of ribosomes per minute. B chain facilitates the entry of A chain into the cell. 

ricin, RTA subunit

store at -70°C; avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes. For storage at 4°C sodium azide can be added.

ELISA (ELISA), immunohistochemistry (IHC)

AS09 649 | ricin whole molecule, clone MMH

collection of antibodies to food proteins

Antibodies have been purified by affinity chromatography on Protein G from tissue culture supernatant.

Ricin detection limit is 5 ng/ml, signal to noise ratio is 15-50 up to 100 ng/ml
