Macrophage Colony Stimulating Factor Human Recombinant, HEK

Description	M-CSF Human Recombinant produced in HEK cells is a glycosylated homodimer, having a molecular weight range of 35-40kDa due to glycosylation. The M-CSF is purified by proprietary chromatographic techniques.
Synonyms	Macrophage Colony Stimulating Factor, CSF-1, Lanimostim, MCSF, MGC31930, M-CSF.
Source	HEK.
Purity	>96% as determined by SDS-PAGE and HPLC
Formulation	Sterile Filtered White lyophilized (freeze-dried) powder. The M-CSF was lyophilized from 1mg/ml in 1xPBS.
Stability	The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity	The specific activity was determined by the dose-dependent stimulation of the proliferation of murine M-NFS-60 cells (Mouse Myeloid Leukemia indicator cell line) and is typically 0.5-4ng/ml.
Solubility	It is recommended to reconstitute the lyophilized M-CSF in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Usage	LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
