GMP Recombinant Human Granulocyte Macrophage-Colony Stimulating Factor (rh GM-CSF)
Order No.: 1012-050
Source
A DNA sequence encoding the mature GM-CSF protein (Cantrell,M. et al., 1985,PNAS 82:6250-6254; Lee, F. et al., 1985, PNAS 82:4360-4364; and Wong. et al.,1985, Science 228:810-815) was expressed in E. coli
Molecular mass
The methionyl form of the E. coli expressed mature human GM-CSF contains 128 amino acid residues and has a molecular mass of approximay 14.5 kDa
Identity
Confirmed by DNA-sequencing of the expression plasmid in end of production (EOP)-cells and N-terminal sequencing of the final product
Purity
≥97%, as determined by SDS-PAGE(under reducing and non-reducing conditions) and visualized by Coomassie staining
Endotoxin level
< 1000 EU/mg, as determined by LAL gel clot test according to Ph.Eur.typically < 100 EU/mg
Residual host-cell DNA
≤200 ng/mg, as determined by a fluorimetric assay
Activity
0.5x107–2.0x107IU/mg calibrated with the 1st International Standard NIBSC,# 88/646Measured in a cell proliferation assay using a human factor-dependent cell line,TF-1 (Kitamura, T. et al., 1989, J. Cell Physiol. 140:323-334)
Sterility
Sterility test according to Ph.Eur. of the vialed product (direct inoculation)
Formulation
Lyophilized from a 250 μg/ml, 0.2μm sterile-filtered solution in PBS without anycarrier materials and preservatives
