Application: | Phytohemagglutinin-L (PHA-L) consists of only L-type subunits (isolectin L4, "leuko-agglutinin"), and is well suited for high-efficiency induction and the functional analysis of T-lymphocytes. It is highly purified and tested for high-efficiency stimulation of human lymphocytes. It is also used as positive controls for peripheral blood mononuclear cells (PBMC) stimulation. |
Biochem/physiol Actions: | Phytohemagglutinin (PHA) has mitogenic and potent cell agglutinating activities. It binds to T-cell membranes and stimulates cell division and metabolic activity. PHA has the ability to stimulate close contacts between cell membranes. |
General description: | PHA-L is purified from Phaseolus vulgaris (red kidney bean) by standard chromatographic techniques. Phytohemagglutinin (PHA), the lectin extract from the red kidney bean, consists of only L-type subunits (isolectin L4, "leuko-agglutinin"). It is an N-acetylgalactosamine/gala |
Other Notes: | For life science research only. Not for use in diagnostic procedures. |
Preparation Note: | Working concentration: 1 to 5 μg/ml Approximately 1 to 5 μg/ml for the stimulation of human peripheral blood lymphocytes Storage conditions (working solution): -15 to -25 °C The reconstituted solution is stable at -15 to -25 °C. Note: Store the reconstituted solution in aliquots at -15 to -25 °C. Avoid repeated freezing and thawing. |
Sequence: | PHA-L is a tetramer of 4 L-type subunits held together by noncovalent forces. |
Specifications: | Biological activity: <5μg/ml for maximal stimulation of DNA synthesis (BrdU incorporation) with human peripheral blood lymphocytes |
