Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.

NR-32831 is a preparation of Abrin which has been chemically inactivated by treatment with formalin. Mature Abrin toxin has a molecular weight of approximately 60,000 daltons, however, formalin fixation can induce cross linking which may interfere with how the toxoid behaves in SDS-PAGE and the band may appear larger than expected.

Each vial of NR-32831 contains approximately 0.1 mg of Abrin toxoid in PBS.

NR-32831 is reactive with anti-Ricin polyclonal antiserum, NR-862 on western blots. Abrin does share similarity with Ricin and some cross reactivity is expected. NR-32831 is approximately 100,000 times less active than the active toxin in an in vitro cytotoxicity assay using Vero cells.
