Active Recombinant Human CSF2 Protein

• Cat.No.: CSF2-142H
• Product Overview: Recombinant Human Granulocyte-Macrophage Colony-Stimulating Factor is produced by our Yeast expression system and the target gene encoding Ala18-Glu144 is expressed.

Specification

• Species: Human
• Source: P.pastoris
• ProteinLength: 18-144 a.a.
• 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 of immune and inflammatory stimuli. Besides granulocyte-macrophage progenitors, GM-CSF is also a growth factor for erythroid, megakaryocyte and eosinophil progenitors. On mature hematopoietic, monocytes/macrophages, and eosinophils, GM-CSF has also been reported to have a functional role on non-hematopoitic cells. It can induce human endothelial cells to migrate and proliferate. Additionally, GM-CSF can also stimulate the proliferation of a number of tumor cell lines, including osteogenic sarcoma, carcinoma and adenocarcinoma cell lines.
• Form: Lyophilized from a 0.2 um filtered solution of 10mM TrisHCl, 4% Mannitol, 1% Sucrose, pH 8.5.
• Bio-activity: Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells. The ED50 for this effect is 6-30 pg/ml.
• Molecular Mass: Predicted Molecular Weight: 14.4kDa
  Apparent Molecular Weight: 24-35kDa, reducing conditions.
• AA Sequence: Ala18-Glu144
