C	Healthy humanc				5.12	0.39d

^a Precursor activity <0.85 is unable to support activation of macrophages and that is considered to be loss of activity

^b Nagalase assayed before entering GcMAF therapy

^c Average of six healthy humans

^d This activity level is enzyme activity of α-galactosidase and not of Nagalase
