Lectin from Phaseolus vulgaris (red kidney bean) is used in Lymphocyte Transformation Assay and culture medium.[1]

Azioni biochim/fisiol

PHA consists of two molecular species, an erythroagglutinin (PHA-E) which has low mitogenic activity and high erythroagglutinin activity, and leucoagglutinin (PHA-L) which has high mitogenic and leucoagglutinating activity, but very low erythroagglutinating activity.
PHA-E is not blood group specific, but agglutination can be inhibited by certain oligosaccharides. PHA-P is the protein form of PHA prior to separation and purification of erythroagglutinin and leucoagglutinin. PHA-M is the mucoprotein form. Conjugates are prepared from the corresponding purified lectins.

Risultati analitici

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.

Domande

  1. What do the designations -P, -L, -M, and -E represent in the names of PHA products?

    1 risposta

    1. Generally, PHA-P or PHA-L is utilized to stimulate lymphocytes, although PHA-M will also work, but not to the same degree. The most active form is PHA-L (the mitogenic concentration is < 5μg/ml). PHA, or Phytohemagglutinin, comprises two molecular species:

      1. Erythroagglutinin (PHA-E), which demonstrates low mitogenic activity and high erythroagglutinating activity.

      2. Leucoagglutinin (PHA-L), which possesses high mitogenic and leucoagglutinating activity, accompanied by very low erythroagglutinating activity.

      PHA-P represents the protein form of PHA before the erythroagglutinin and leucoagglutinin components are separated and purified. PHA-M refers to the mucoprotein form of Phytohemagglutinin.
