Storage/Handling: Upon receipt, aliquot and store AstroFectagen reagent A at -20°C, avoid repeated freezing/thawing cycles. Once thawed, store AstroFectagen reagent A at 4°C and use in a month. AstroFectagen reagent B can be kept at 4°C.
Quality Control: Each lot of AstroFectagen is performance tested by transfecting Human Astrocytes (HAs, Cat. No. SC1800) with Promega® ρSV-bata-Galactosidase control vector. Gene expression is assayed by X-gal staining 24 hours post transfection. Typically, 20-45% transfection efficiency can be achieved.
