Abstract: The invention provides systems and methods for evaluating synthetic reactions such as polymer synthesis reactions. Evaluation of a synthetic reaction product can be based on a quantitative measure of synthesis such as coupling efficiency or yield, and various parameters determined from a separation record obtained for the synthetic reaction product. The invention further provides methods for evaluating a separation method based on various parameters determined from a separation record. The invention can be used to select an appropriate treatment for a synthetic reaction product such as a separation treatment or treatments related to further processing for the desired product. The methods are particularly useful for automated selection of treatments for synthetic reaction products.

Abstract: The present invention provides a method for detecting a target analyte by providing a substrate having attached polynucleotides and a stabilization polymer layer; removing the stabilization polymer layer; contacting the substrate with a target analyte; and detecting the target analyte.

Abstract: The subject invention provides a method for analyzing the metabolic activity in cells by improving the retention of a detectable reporter molecule only in intact cells where a particular enzyme is present. In particular, improved retention results from a two part process involving conjugation of haloalkyl-substituted derivatives of a reporter molecule with intracellular cysteine-containing peptides while unblocking the reporter molecule. The method for analyzing metabolic activity of cells involves the use of a substrate having the formXR-REPORTER-BLOCKwherein -BLOCK is a group selected to be removable by action of a specific analyte, to give REPORTER spectral properties different from those of the substrate,-REPORTER- is a molecule that, when no longer bound to BLOCK by a BLOCK-REPORTER bond, has spectral properities different from those of the substrate, andXR-- is a haloalkyl moiety that can covalently react with an intracellular thiol (Z--S--H) to form a thioether conjugate (Z--S--R--).

Abstract: Novel fluorescent precipitating substrates made from a class of fluorophores, generally including quinazolinones (quinazolones), benzimidazoles, benzothiazoles, benzoxazoles, quinolines, indolines, and phenanthridines, having the general formula: ##STR1## where carbon atoms of --C.sup.1 .dbd.C.sup.2 -- are further joined so as to complete a first 5- or 6-membered aromatic ring which may contain at least one of the hetero atoms N, O or S,where carbon atoms of --C.sup.4 --N.dbd.C.sup.3 -- are further joined so as to complete a second 5- or 6-membered aromatic ring that contains at least the nitrogen between C.sup.3 and C.sup.4 and may contain at least one additional hetero atom N, O or S,where the first and second aromatic rings may be joined by a 5- or 6-membered bridging ring that contains at least the C.sup.2 from the first aromatic ring and the C.sup.
