产品描述

概述

Macrophage Colony Stimulating Factor (M-CSF), also named CSF-1, is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. It is produced by osteoblasts (as a result of endocrine stimulation by parathyroid hormone) exerts paracrine effects on osteoclasts and can interact with CSF1R. M-CSF is a four α-helical bundle cytokine and its active form is found extracellularly as a disulfide-linked homodimer. Four transcript variants encoding three different isoforms have been reported for M-CSF gene. Although forms may vary, all of them contain the N-terminal 150 a.a. portion that is necessary and sufficient for interaction with the receptor. The first 229 a.a. of mature mouse M-CSF shares 87 %, 83 %, 82 % and 81 % sequence identity with corresponding regions of rat, dog, cow and human M-CSF, respectively. Human M-CSF is active in the mouse, but mouse M-CSF is reported to be species-specific.

技术规格

Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Purity > 95 % by SDS-PAGE and HPLC analyses.
Source Escherichia coli.
Biological Activity Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine M-NFS-60 cells is less than 2 ng/ml, corresponding to a specific activity of > 5.0 × 105 IU/mg.
Formulation Lyophilized from a 0.2 μm filtered solution in 20 mM Tris, 500 mM NaCl, pH 7.4.
Endotoxin Less than 1 EU/μg of rMuM-CSF as determined by LAL method.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
