The Applied Biosystems® MicroAmp® Optical 384-Well Reaction Plate with Barcode is designed to provide unmatched temperature accuracy and uniformity for fast, efficient PCR amplification. This plate, constructed from a single rigid piece of polypropylene in a 384-well format, is designed to work with Applied Biosystems® 384-well Real-Time PCR systems and thermal cyclers.- Frosted to minimize interfering fluorescence from wells of cycling block- Screened to eliminate auto-fluorescent plates- Unique design provides a barrier to ambient air to help ensure well-to-well temperature uniformity- Each reaction plate includes a unique serialized, eight character number label (barcode) that is user-readable and machine-readable to prevent tracking errors
