Pozdrav svima.
Dosao sam u posed nekih peptida od kojih je jedan IGF LR3 (Magnus) i sad u toku istrazivanja o istim naisao sam na jedan problem a to je cuvanje tj skladistenje gde neka zvanicna istrazivanja pisu jedno a na samom uputstvu nesto sasvim drugo. Na samom uputstvu pise da se moze cuvati na sobnoj temperaturi do mesec dana a u frizideru 20 dana,pa tu onda ljudi diskutuju o tome da to nije tacno i da na sobnoj temperaturi dolazi do "izumiranja peptida "... Posto nisam obavesten dobro o peptidima (sem citanja raznih foruma itd) zanima me vase misljenje i iskustva.
A evo i tog istrazivanja -
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
