Human G CSF Protein

SKU: orb425607

Description

Recombinant of human G CSF protein

Research Area

Immunology & Inflammation

Images & Validation

Application Notes
Protein content: GCSF quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 0.815 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of GCSF as a Reference Standard

Key Properties

SourceEscherichia Coli
Biological ActivityThe ED50, calculated by the dose-dependant proliferation of murine NFS-60 indicator cells (measured by 3H-thymidine uptake) is < 0.1 ng/ml, corresponding to a Specific Activity of 100,000,000 IU/mg.
PurityGreater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Protein SequenceThe sequence of the first five N-terminal amino acids of GCSF was determined and was found to be Met-Thr-Pro-Leu-Gly

Storage & Handling

StorageStability: Lyophilized GCSF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GCSF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles
Form/AppearanceSterile Filtered White lyophilized (freeze-dried) powder.
Buffer/PreservativesGCSF was lyophilized after extensive dialysis against 10mM sodium acetate buffer pH= 4.
Expiration Date6 months from date of receipt.
DisclaimerFor research use only
