Recombinant Human CSF3 Protein
Recombinant human GCSF isoform b (NP_757373.1) (Ala30-Pro204) was expressed.
Predicted N Terminal:
Lyophilized from sterile sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Measured in a cell proliferation assay using NFS-60 mouse myelogenous leukemia lymphoblast cells.The ED50 for this effect is typically 0.04-0.2 ng/mL.
The recombinant human GCSFb consists of 175 amino acids and has a calculated molecular mass of 18.7 kDa. It migrates as an approximately 18 kDa protein in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>90 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
