Description

Actions biochimiques/physiologiques

BS-I has a major affinity for terminal α-D-galactosyl residues with a secondary affinity for terminal N-acetyl-α-D-galactosaminyl residues.

Autres remarques

BS-I is a tetrameric lectin consisting of two types of subunits designated A and B. There are five BS-I isolectins with different subunit composition: BSI-B₄, BSI-AB₃, BSI-A₂B₂, BSI-A₃B and BSI-A₄. BSI-B₄ is blood group B specific and has an exclusive affinity for terminal α-D-galactosyl residues, whereas BSI-A₄ has blood group A specificity and has a major affinity for terminal N-acetyl-α-D-galactosaminyl residues.

Notes préparatoires

Purified by affinity chromatography using the method of Hayes, C. E., and Goldstein, I. J., J. Biol. Chem., 249, 1904 (1974).

Remarque sur l'analyse

Agglutination activity is expressed in μg/mL and is determined from serial dilutions of a 1 mg/mL solution using phosphate buffered saline, pH 6.8, containing, for each lectin, calcium, magnesium, and manganese at different concentrations. This activity is the lowest concentration to agglutinate a 2% suspension of appropriate erythrocytes after 1 hr incubation at 25 °C.
