Storage/Handling: Upon receipt, aliquot and store MesenFectagen reagent A at -20°C, avoid repeated freezing/thawing cycles. Once thawed, store MesenFectagen reagent A at 4°C and use in a month. MesenFectagen reagent B can be keptat 4°C.
Quality Control: Each lot of MesenFectagen is performance tested by transfecting Human Mesenchymal Stem Cells (HMSCs,Cat. No. SC7500, ScienCell™) with Promega® ρSV-bata-Galactosidase control vector. Gene expression is assayedby X-gal staining 24 hours post transfection. Typically, 20-35% transfection efficiency can be achieved.
