Storing Glutathione: Best Practices
Polvo Liofilizado
Almacenar a -20°C para una estabilidad óptima a largo plazo, o a 2–8°C para almacenamiento de rutina. La forma de polvo seco es relativamente estable, pero debe mantenerse en recipientes opacos y herméticamente sellados para protegerlo de la luz y la humedad. El glutatión es altamente susceptible a la oxidación en presencia de aire y humedad elevada (actividad acuosa >0,3).
Solución Reconstituida
Disolver en agua estéril o PBS (solución salina tamponada con fosfato). Las soluciones acuosas de GSH se oxidan rápidamente a GSSG cuando se exponen al aire. Alicuotar las soluciones madre inmediatamente después de su preparación para minimizar los ciclos de congelación-descongelación. Almacenar las alícuotas a -20°C y utilizarlas con prontitud después de descongelar. Para uso a corto plazo, mantener a 2–8°C y consumir dentro de las 24 horas.
Calidad y Manejo
Suministrado como polvo cristalino blanco. Pureza: ≥98% por HPLC. Identidad verificada por HPLC, espectrometría de masas (307,32 g/mol) y ensayo de reciclaje enzimático. Incompatible con agentes oxidantes fuertes. En entornos de laboratorio, las soluciones preparadas deben mantenerse con temperatura controlada y protegidas de la luz hasta inmediatamente antes de su uso. CAS: 70-18-8, PubChem CID: 124886.
