M-CSF ELISA Kit (Macrophage Colony-Stimulating Factor)

INTENDED USE

Human M-CSF ELISA kit is a reliable quantitative procedure for measuring macrophage colony-stimulating factor (M-CSF, MCSF) in human tissue homogenates, plasma, biological fluids and serum. This assay has a minimum sensitivity detection limit of 18.75 pg/ml.

BACKGROUND

Macrophage colony stimulating factor (MCSF, M-CSF) is a hematopoietic growth factor. It is important for the proliferation, differentiation, survival of macrophages, bone marrow progenitor cells and monocytes. It affects monocytes or macrophages by both increasing the cytotoxicity of tumour cell and increasing the stimulation of chemotactic/ phagocytic activity.

There is evidence that eukaryotic cells produce M-CSF in order to combat any intercellular viral infection. It is also known to play a crucial role in renal pathology that includes chronic renal failure and acute kidney injury. Also, through the interaction with its M-CSF-receptor it can modulate the proliferation of earlier hematopoietic progenitors, resulting in influencing a number of physiological processes that are involved in metabolism, fertility, pregnancy and immunology.
