The average basal level expression of PLC (equivalent to the number of G proteins) per uM2 is 1 to 40 (study from FRET assay, http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812500/).
The average diameter of mammalian cell is 15 uM, So surface area is around 707 uM2. Then the number of PLC per cell varies from 707 to 28280 based on the type of cell.
