Stability Data for LongTMR3IGF-I (Liquid Formulations)

The stability of a liquid solution of LongTMR3IGF-I was monitored for a period of two years at storage conditions of -20 C, +4 C, +22 C, and +37 C. The final concentration of LongTMR3IGF-I was in acetic acid. At various time points, samples were taken and compared to a lyophilized control (stored at 4 C). Listed below are the stability results for each respective storage condition.

 Storage Condition: -20 C

Biological Potency No Change up to 2 years
Immunological Activity No Change up to 2 years
Mobility of Protein No Change up to 2 years
Elution Profile by reversed phased HPLC No Change up to 2 years

 Storage Condition: +4 C

Biological Potency No Change up to 2 years
Immunological Activity No Change up to 2 years
Mobility of Protein No Change up to 2 years
Elution Profile by reversed phased HPLC No Change up to 2 years

 Storage Condition: +22 C

Biological Potency No Change up to 2 years
Immunological Activity No Change up to 2 years
Mobility of Protein No Change up to 2 years
Elution Profile by reversed phased HPLC No Change up to 2 years

 Storage Condition: +37 C

Biological Potency No Change up to 1 year
Immunological Activity No Change up to 1 year
Mobility of Protein No Change up to 1 year
Elution Profile by reversed phased HPLC No Change up to 1 year

 Conclusions

o There is no significant difference in the potency of LongTMR3IGF-I associated with the storage of the liquid formulation when stored at this range of temperatures.
o There is no evidence for loss of biological activity at any of the tested temperatures when stored as a liquid product.

Did you mix it with acetic acid,if so then it will be fine.
