Biological Activity

Pokeweed mitogen (PWM) is extracted from pokeweed roots. This protein has hemagglutinating, leukoagglutinating, and mitogenic properties. PWM is not blood group specific, but has affinity for N-acetyl-β-D-glucosamine oligomers.

Lectins are proteins of plant origin, which have the ability to bind to certain neuronal surface glycoproteins and glycolipids. Pokeweed lectin (PL) is a lectin specific for N-acetylglucosamine-containing saccharides that stimulate peripheral lymphocytes to undergo mitosis by binding to their cell surfaces.

Lectin from Phytolacca americana (pokeweed) is used for proliferation Assay. (Cellular proliferative responses were measured by the incorporation of 3H thymidine in newly synthesized DNA, using a conventional assay).

Chemical Information
CAS Number 63231-57-2
Solubility (25°C) PBS: 1 mg/mL
Storage 2-8°C, sealed
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
