NR-43946 is a preparation of the B subunit of abrin toxin from Abrus precatorius (A. precatorius) seeds. The B subunit was separated from the A subunit by galactose affinity chromatography and has a molecular weight of approximately 31,000 daltons. This preparation may contain several isotypes of the B subunit.

Each vial contains approximately 0.05 mg of the B subunit of abrin toxin in PBS.

NR-43946 is reactive with anti-Ricin polyclonal antiserum, BEI Resources NR-862, on western blots. Abrin shares some similarities to Ricin and cross-reactivity is expected. NR-43946 shows approximately 3 logs less toxicity than the active toxin in an in vitro cytotoxicity assay using Vero cells.
