Abstract
The present invention concerns methods and apparatus for detecting and/or identifying analytes, using arrays of binding moieties. In preferred embodiments, the arrays are attached to glass slides. Fluorescent signals obtained from the slides are analyzed by a digital image subtraction method. In preferred embodiments, the glass slides are labeled using a binary code that may be used to identify the lot number and/or date of manufacture of the arrays.
