Macrophage phagocytic activity assay using macrophage cell line THP-1 and fluorescent beads.
Macrophage cell line THP-1 incubated (A) without GcMAF and (B) with second-generation GcMAF (500 ng/ml GcMAF for 120 min) after addition of fluorescent beads (red) starts to give off red fluorescence after engulfment. Although red fluorescent beads were found within macrophages in both treatment groups A and B (indicated by white arrow), a much larger number of florescent beads were stacked beside the nucleus (blue) in the GcMAF treatment group. This result shows that second-generation GcMAF strongly activates macrophages and enhances the engulfment of beads used in this assay system. THP-1 cell line macrophages were induced by 10ng/ml 12-O-Tetradecanoylphorbol-13-acetate (TPA).

(B) Macrophages activated by Second-Generation GcMAF show very high phagocytic activity seen by the much larger number of red florescent beads engulfed by the macrophages.

Increased rate of maturation of dendritic cells (DCs) in vitro
In vitro experiments conducted by Saisei Mirai indicate increased rate of maturation of dendritic cells (DCs), a type of immune cell, with second-Generation GcMAF. This graph shows specific marker expression of dendritic cells grown from normal peripheral blood with and without second-generation GcMAF after 6 and 8 days cultivation. From this preliminary experiment we observed that second-generation GcMAF increases the rate of maturation of dendritic cells.
The ability of dendritic cells to regulate immunity is dependent on DC maturation. The process of DC maturation, results in an increase in the surface expression of costimulatory molecules, morphological changes (such as formation of dendrites), secretion of chemokines, cytokines and proteases, and surface expression of adhesion molecules and chemokine receptors.

How Does the Test Work?
Mature DCs are detected by the presence or absence of various molecules on their cell surface. These include molecules such as CD83+, HLA-DR+, CD86+, CD1a, CD11c which can be measured.

Oral Colostrum GcMAF macrophage activity assay
100 ng Oral Colostrum MAF has a macrophage phagocytic activity equivalent to 10 ng of first-generation GcMAF. Pure colostrum shows no significant activity compared to the control sample, so pure colostrum does not activate macrophages unless modified using our patented technology.
Oral colostrum MAF (macrophage activating factor) is administered orally in the gut in enteric capsules and as a powder. This activates macrophages in the lymphoid tissue of the gut and mouth which are important parts of the human immune system.
