The BRAND Insert 2in1 can be used as both a standing insert and a hanging insert. When used as a hanging insert, it fits nearly all standard multi-well plates. In larger wells and culture dishes, the insert can be used in a standing position. The cell culture insert is available for 6-, 12-, and 24-well plates and in two pore sizes (0.4µm and 8.0µm) with PC or PET membrane. The cellGrade™ plus surface of the membranes ensures optimal cell attachment and growth. They are available individually packed or in multi-packs. Common applications include co-culture, transmigration, chemotaxis, transport/barrier analysis (TEER), cytotoxicity and air-lift culture assays.
