The SYPRO® Photographic Filter optimizes the sensitivity of detection when gels and blots stained with SYPRO® Stains (e.g., SYPRO® Ruby Gel Stain, SYPRO® Tangerine Gel Stain, or SYPRO® Ruby Protein Blot Stain) are photographed with a Polaroid® camera and Polaroid® black and white print film. This filter also provides the ideal photographic filter for Coomassie Fluor™ Orange Gel Stain, and DDAO, the red-fluorescent product used in Pro-Q® Western Blot Immunodetection Kits. Obtain high sensitivity without the need for investing in expensive imaging devices. For CCD camera systems and laser scanners, contact the camera manufacturer for recommendations on the most suitable filter.
