Dissolved 13C6-L-Leucine in saline stability at -20/80ºC?

06 March 2024 1 2K Report

I am working with isotopic tracing studies. I was wondering if we can resuspend the whole vial of 13C6-Leucine with saline, aliquot it and freeze it at -20 or -80ºC? Is it stable? For how long?

Eef Dirksen

I think you'll be fine, especially when freezing at -80. You can probably keep it stable for several years.
