Mouse IGF1 Protein

Recombinant of Mouse IGF1 protein

Product Specifications

Product Name Alternative

Somatomedin C, IGF-I, IGFIA, IGF1.

Source

Escherichia Coli

Purity

Greater than 98.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.

Bioactivity

The ED50, calculated by the dose-dependant proliferation of murine BALB\C 3T3 cells (measured by 3H-thymidine uptake) is < 1.0 ng/ml, corresponding to a specific activity of 1MU/mg.

Form

Sterile Filtered White lyophilized (freeze-dried) powder.

Solubility

It is recommended to reconstitute the lyophilized IGF1 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.

Storage Conditions

Stability: Lyophilized IGFI although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IGF-1 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

Notes

For research use only.

Applications Notes

Protein content: Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.47 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 IGF-I as a Reference Standard
