The ED50, calculated by the dose-dependant proliferation of BALB/c 3T3 indicator cells (measured by 3H-thymidine uptake) is < 1ng/ml, corresponding to a Specific Activity of 1MIU/mg.
Lyophilized from 10mM Acetic Acid.
Sterile Filtered White lyophilized (freeze-dried) powder.
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.55 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 standard solution of PDGF-BB as a Reference Standard.
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Platelet-derived Growth Factor-BB in 100mM Acetic Acid.
Lyophilized Platelet-derived Growth Factor BB although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution PDGF BB should be stored at 4oC between 2-7 days and for future use below -18oC.
Please prevent freeze-thaw cycles.
