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.


Macrophage colony stimulating factor (MCSF, M-CSF) which is also known as colony stimulating factor 1 (CSF1) is a hematopoietic growth factor that is important for the proliferation, differentiation, and survival of macrophages, bone marrow progenitor cells and monocytes. Human M-CSF are able to affect monocytes or macrophages in many ways including increasing the cytotoxicity of tumour cell and increasing the stimulation of chemotactic or phagocytic activity. Also, through the interaction with its membrane 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.

There is evidence that eukaryotic cells are able to 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.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
