Cytokine, Chemokines & Growth Factors |
| Description |
GM-CSF was initially characterized as a growth factor that can support the in vitro colony formation of granulocyte-macrophage progenitors. It is produced by a number of different cell types (including activated T cells, B cells, macrophages, mast cells, endothelial cells and fibroblasts) in response to cytokine or immune and inflammatory stimuli. Besides granulocyte-macrophage progenitors, GM-CSF is also a growth factor for erythroid, megakaryocyte and eosinophil progenitors. On mature hematopoietic cells, GM-CSF is a survival factor for and activates the effector functions of granulocytes, monocytes/macrophages and eosinophils. |
| M.W. |
Approximately 14.4 kDa, a single non-glycosylated polypeptide chain containing 127 amino acids. |
| Purity |
>98% by SDS-PAGE and HPLC analyses. |
| Endotoxin Level |
Less than 0.2EU/ug of rRhGM-CSF as determined by LAL method. |
| Specific Activity |
Fully biologically active when compared to standard. The ED50 as calculated by the dose-dependant stimulation of the proliferation of human TF-1 cells is less than 0.1 ng/ml, corresponding to a Specific Activity of 1.0x107 IU/mg. |
| Storage |
This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 C to -70 C. Avoid repeated freeze/thaw cycles. |
| Formulation |
Lyophilized from a 0.2um filtered concentratedcsolution in PBS, pH 7.4. |
| 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 <-20C. Further dilutions should be made in appropriate buffered solutions. |
| Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
