Lifespan of IGF-1

The stability of a liquid solution of LR3IGF-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 LR3IGF-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 (-4 F)
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 (39.2 F)
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 (71.6 F)
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 (98.6 F)
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

Bacteriostatic can still be used, but IGF calls for Acetic Acid since it`s the PH levels in the acid that maintain the integrity and quality of the IGF...BW reconstitution will last for about 1 to 2 weeks on average...

Now with BW, are we talking it begins to degrade after a week or 2 ?

or does it not have any traces of IGF1 after the 2 week period?

interesting stuff action, mines still staying in the fridge though but good to know!

Ya, that's my understanding...I was using the 1000 mcg kit from Chem One Research but I'm now using the Chinese blue top 100 mcg vials...So BW is fine because it takes me 2 days to finish one vial once reconstituted...
