These plastic containers in which the UltraGAPS™ Coated Slides are shipped also function as storage boxes for printed arrays. The orange colored plastic has low transmittance in the 500 to 700 nm wavelength range which helps protect Cy®3 and Cy®5 dyes from photobleaching. These rigid plastic containers do not shed particles or out-gas volatile chemicals that may contaminate microarray slides. The Corning® 25 Slide Holder has a lift off lid which is easy to open and close. -Cy is a registered trademark of Amersham plc, Buckinghamshire, England.
