Toxicon, 1971
Abstract Crystalline abrin contained 4·9 per cent of neutral sugar in addition to 9·3 residues of glucosamine per mole of abrin (molecular weight 65,000). The neutral sugars consist of mannose, xylose and fucose in ratios of 2·08:1·00:0·94. When abrin was treated with periodate, the residual toxicity was only a few per cent of that of native abrin ...

Trends in the analysis of abrin poisoning for forensic purposes.
Journal of Forensic and Legal Medicine, 2023Abrus precatorius is a poisonous plant known since ancient times. Accidental poisoning is more common due to the intake of plant seeds containing deadly abrin which is a highly toxic and a thermolabile plant toxalbumin. Abrin has also been reported to be

Abrin is a toxic protein obtained from the seeds of Abrus precatorius (jequirity bean), which is similar in structure and properties to ricin. Abrin is highly toxic, with an estimated human fatal dose of 0.1-1 microgram/kg, and has caused death after accidental and intentional poisoning.

Abrin is a toxin from the seeds of Abrus precatorius. Abrin is considerably more toxic than ricin and a potent bio-warfare agent. The mechanism of abrin induced hepatotoxicity remains unclear.

ISOLATION OF ANTITUMOR PROTEINS ABRIN‐A AND ABRIN‐B FROM ABRUS PRECATORIUS*
International Journal of Peptide and Protein Research, 1978Two toxic proteins were purified from the seeds of Abrus precatorius by DEAE‐A 50 and Sepharose 4B chromatography. One of them does not bind on the Sepharose 4B column (Abrin‐b) and the other (Abrin‐a) is eluted with 0.2 M galactose. The amino acid compositions and tryptic maps of these two proteins were similar, but not identical.

Here we describe an affinity molecule-directed surface plasmon resonance (SPR) immunosensor for a label-free, differentiation and quantification of ricin and abrin from their structural highly like agglutinin biotoxins. By an introduction of protein G as

Toxicon, 2017
Abrin, a type II ribosome inactivating protein from the Abrus precatorius plant, is extremely toxic. It has been shown to be 75 times more potent than its infamous sister toxin, ricin and their potential use in bio-warfare is a cause of major concern.

Radioimmunoassays of abrin and ricin in blood
Journal of Toxicology and Environmental Health, 1981Radioimmunoassays for abrin and ricin are described. There is little cross-reactivity between the two toxins. The procedures described are capable of determining blood concentrations down to 50-100 pg/ml, permitting identification of abrin and ricin poisoning and monitoring of the blood concentrations in cancer patients treated with these agents.
