M-CSF Protein, Cynomolgus/Rhesus Macaque (HEK293, Fc)

The M-CSF protein regulates hematopoietic precursor cells, promoting their survival, proliferation, and differentiation. M-CSF Protein, Cynomolgus/Rhesus Macaque (HEK293, Fc) is the recombinant Rhesus Macaque, cynomolgus-derived M-CSF protein, expressed by HEK293 , with C-hFc labeled tag. The total length of M-CSF Protein, Cynomolgus/Rhesus Macaque (HEK293, Fc) is 190 a.a., with molecular weight of ~45.1 kDa.

M-CSF Protein assumes a crucial role in orchestrating the regulation of survival, proliferation, and differentiation of hematopoietic precursor cells, particularly mononuclear phagocytes, including macrophages and monocytes. Its significance extends to promoting the release of pro-inflammatory chemokines, thereby playing a pivotal role in innate immunity and inflammatory processes. Moreover, M-CSF is a key player in the regulation of osteoclast proliferation and differentiation, influencing bone resorption and contributing to normal bone development. Beyond its impact on the skeletal system, M-CSF is indispensable for normal male and female fertility. The cytokine also plays a role in lipoprotein clearance and contributes to cellular processes such as reorganizing the actin cytoskeleton, regulating the formation of membrane ruffles, cell adhesion, and cell migration. M-CSF can exist in various forms, including a homodimer with two identical 150-200 kDa proteoglycan subunits, a heterodimer with a 150-200 kDa proteoglycan subunit and a truncated 43 kDa subunit, and a homodimer with two identical 43 kDa subunits. It interacts with its receptor CSF1R to exert its diverse functions.

Measured in a cell proliferation assay using M-NFS-60 mouse myelogenous leukemia lymphoblast cell. The ED₅₀ for this effect is typically 25-140 ng/mL.

Approximately 45.1 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
