What is PHA in cell culture?

Phytohemagglutinin (PHA) is a lectin, obtained from the red kidney bean that binds to the membranes of T-cells and stimulates metabolic activity, cell division, etc. Our results indicate that the preparation of fresh Phytohemagglutinin at the time of cell division and cell culture procedure reveals satisfactory score.
