Hi cort, this is the definition given in some of Yamamoto's studies:
Gc1F protein was purified using 25-hydroxyvitamin D3-affinity chromatography [Link et al., 1986]. Stepwise incubation of the purified Gcprotein with immobilized bgalactosidase and sialidase yielded probably the most potent macrophage activating factor (GcMAF) ever discovered
The molecular structure of GcMAF is identical to thatof the native human MAF
Gc protein carries one trisaccharide composed of N-acetylgalactosamine with dibranched galactose and sialic acid termini at 420 threonine residue [Yamamoto and Homma, 1991; Yamamoto, 1993, 1996; Yamamoto and Kumashiro, 1993]. Stepwise hydrolysis of Gc protein with the inducible membranous b-galactosidase (Bgli) of inflammation- primed (or lyso-Pc-treated) B lymphocytes and the Neu-1 sialidase of T lymphocytes yields the macrophage activating factor (MAF)
Hope this help...
Saluditos,
