Specially designed western blot boxes to fit blots of any size, including whole blots, half blots, and strips. The blot boxes are constructed of ultra-clear, durable, polystyrene plastic with a flat, smooth inner surface and hinged lids to reduce evaporation. The 90â° edges create optimal membrane movement for more efficient incubation. With multiple sizes available, you can use a properly sized blot box for your needs to reduce the volume of antibodies required.
