The ED50 as determined by the dose-dependent stimulation of thymidine uptake by 3T3 cells in the presence of heparin is 0.5 ng/ml, corresponding to a specific activity of >2 x10^5units/mg.
1 mg/ml solution of 5 mM NaP, pH 7.5 + 75 mM NaCl.
Storage
Reconstitute in water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4ºC for 1 week or –20ºC for future use. Repeated freeze/thaw cycles will result in some loss of activity.
Antigen Species
Mouse
Expression System
E. coli
Purification
Purity was assessed by SDS-PAGE (≥98%) and by HPLC (≥98%).
