Product Specifications
Description
Phytohemagglutinin is a lectin extracted from red kidney beans (Phaseolus vulgaris). The protein consists of two mo- lecular species, a leucoagglutinin (PHA-L) and an erythroagglutinin (PHA-E). Each of the proteins contains a family of five isolectins, each being a tetramer held together by noncovalent forces. PHA-M is the mucoprotein form and is a crude extract used for the stimulation of cell proliferation in lymphocyte culture. PHA-M also has a powerful erythroagglutinating property and it was originally used for separating leukocytes from whole blood.
Storage and Shelf Life
Store at ≤-15 °C. After thawing, the PHA-M is stable for at least 1 month at +2 °C to +8 °C. PHA-M may appear cloudy at +2 °C to +8 °C. The turbidity has no effect on the activity of PHA-M.
