2012 Stability of GcMAF in Serum

  • This experiment was conducted at the University of Tokushima in Japan, using our second-generation GcMAF demonstrating macrophage phagocytic activity after short-term and long-term storage. The results show that second-generation GcMAF in serum is stable for 1 year at 4 °C, for 14 days at room temperature (around 20 °C), and for 7 days at 40 °C.
  • Please note that these values only apply to second-generation GcMAF produced with our production process, patent pending.
  • GcMAF produced using the old method using vitamin D affinity chromatography does not have the same stability as second-generation GcMAF because it is susceptible to much faster oxidation. This difference in stability is due to the different production process, not to the GcMAF itself.

Macrophage phagocytic activity assay of second-generation GcMAF

Macrophage phagocytic activity assay using mouse macrophage

Second-generation GcMAF is tested for macrophage phagocytic activity using mouse macrophages and sheep red blood cells at the University of Tokushima. The red blood cells are opsonized which marks them for ingestion and destruction by activated macrophages, seen as purple areas in the clear cells. From this we calculate the Phagocytosis (ingestion) Index (PI).

The purple color are macrophages activated by GcMAF phagocytizing (ingesting) opsonized red blood cells which are clear in color. Photo courtesy, University of Tokushima.

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.
