Reconstituted by adding 0.5 mL sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C.
Cross-reactivities against enzymes of other sources may occur but have not been determined.
Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at 4°C, not refrozen, and preferably used t he same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the product.
Phospholipase C (PLC) is a class of membrane-associated enzymes that cleave phospholipids just before the phosphate group by hydrolizing a glycerophospholipid at the phosphodiester bond between the glycerol backbone and the phosphate group. All known eukaryotic PLCs utilize only phosphoinositides as substrates. Upon its activation, PLC hydrolyzes PIP2 to modulate numerous PIP2-dependent cellular processes. The two PIP2 cleavage products, inositol 1,4,5-trisphosphate (IP3) and 1,2-diacylglycerol (DAG), are critical second messengers to mediate calcium signaling in animal cells. Thirteen different mammalian PLCs have been identified, grouped into six subfamilies based on their primary structures.
