商品介绍
Species: Human
Host Species: Silkworm
MW: 21 kDa
Genbank #: P09603
a.a: 33–181
Background:
M-CSF is produced by monocytes, granulocytes, endothelial cells, and fibroblasts. After cell activation, B-cells and T- cells and also a number of tumor cell lines are capable also of synthesizing this factor. M-CSF has been found to be synthesized by uterine epithelial cells in vivo. The M-CSF receptor (CD115) is identical with the proto-oncogene fms. The receptor is a transmembrane protein with an extracellular ligand-binding domain of 512 amino acids, an intramembrane domain of 25 amino acids, and a cytoplasmic domain of 435 amino acids encoding a tyrosine kinase. Human M-CSF is active in mouse and rat cells. The murine factor is active in rat cells but inactive in human cells. M-CSF is a specific factor in that the proliferation inducing activity is more or less restricted to the macrophage lineage. M-CSF is a potent stimulator of functional activities of monocytes.
Description:
Recombinant Human M-CSF is a disulfide-linked homodimeric protein consisting of two 149 amino acid residues, and migrates as an approximately 42 kDa protein under non-reducing and as 20-21 kDa under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human M-CSF extracellular domain was expressed in baculovirus infected Bombyx mori.

Purity:
≥95% by SDS-PAGE and HPLC
Endotoxin Level:
<0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity:
The ED50 was determined by the dose-dependent stimulation of the proliferation of of M-NFS-60 cells is < 1.0 ng/ml, corresponding to a specific activity of > 1 x 106 units/mg.
Formulation:
Lyophilized from a 0.2 µm filtered PBS solution pH 7.0 containing 1% HSA, 3% mannitol.
Format:
lyophilized protein
Reconstitution:
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability:
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
