Product Description	Recombinant Human M-CSF/CSF-1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Glu33-Asn190.
Product Background	CSF-1, also known as M-CSF , is a four alpha -helical-bundle cytokine that is the primary regulator of macrophage survival, proliferation and differentiation. CSF-1 is also essential for the survival and proliferation of osteoclast progenitors.CSF-1 is cytokine that plays an essential role in the regulation of survival, proliferation and differentiation of hematopoietic precursor cells, especially mononuclear phagocytes, such as macrophages and monocytes.

Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
