Application

Lectin from Phaseolus vulgaris (red kidney bean) is used in Lymphocyte Transformation Assay and culture medium.

Biochem/physiol Actions

La PHA consta de dos especies moleculares, la eritroaglutinina (PHA-E), que tiene poca actividad mitógena y elevada actividad de eritroaglutinina, y la leoucoaglutinina (PHA-L), que tiene elevada actividad mitógena y leoucoaglutinante, pero muy baja actividad eritroaglutininante
La PHA-E no es específica de grupo sanguíneo, pero la aglutinación puede ser inhibida por ciertos oligosacáridos. La PHA-P es la forma proteica de la PHA antes de la separación y la purificación de la eritroaglutinina y la leoucoaglutinina. La PHA-M es la forma mucoproteínica. Los conjugados se preparan a partir de las correspondientes lectinas purificadas.

Analysis Note

Agglutination activity is expressed in μg/mL and is determined from serial dilutions of a 1 mg/mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes in phosphate buffered saline, pH 6.8, after 1 hr incubation at 25 °C.

Co-stimulatory 4-1BB receptors on tumor-infiltrating T cells are a compelling target for overcoming resistance to immune checkpoint inhibitors, but initial clinical studies of 4-1BB agonist mAbs were accompanied by liver toxicity. We sought to engineer a tri-specific antibody-based molecule that
