Provided herein are compositions and methods for the assembly of a bioluminescent complex from two or more non-luminescent (e.g., substantially non-luminescent) peptide and/or polypeptide units. In particular, bioluminescent activity is conferred upon a non-luminescent polypeptide via structural complementation with another, complementary non-luminescent peptide.

Activation of bioluminescence by structural complementation

Activation of bioluminescene by structural complementation

The present invention relates in general to cellular analysis tools and more particularly to methods and systems for detecting or determining cyclic nucleotide concentrations and related pathway activation in samples. Samples containing cyclic nucleotides may be contacted with a cyclic nucleotide-dependent protein kinase (e.g., cAMP- and cGMP-dependent protein kinases) and a detection system that includes a substrate capable of being phosphorylated by the cyclic nucleotide-dependent protein kinase. The activity of cyclic nucleotide related cell signaling pathways may be measured based on detecting the activity of the cyclic nucleotide-dependent protein kinase.

Systems and methods for determining cyclic nucleotide concentration and related pathway activation

The present invention relates in general to cellular analysis tools and more particularly to methods for detecting or determining cyclic nucleotide concentrations in samples. Samples containing cyclic nucleotides may be contacted with a cyclic nucleotide-dependent protein kinase and a detection system which includes a substrate for the cyclic nucleotide-dependent protein kinase. The activities in cyclic nucleotide related pathways may be measured using the detection system.

Methods for cyclic nucleotide determination

Provided herein are methods for detecting and quantifying succinate in a sample. Also provided are methods for detecting and quantifying 2-oxoglutarate oxygenase enzyme and/or 2-oxoglutarate oxygenase activity in a sample and methods for screening for modulators of 2-oxoglutarate oxygenase activity.

Bioluminescent succinate detection assay

The invention provides compositions and methods to determine or detect the activity of enzymes, including phosphotransferases such as kinases (e.g., protein, lipid, and sugar kinases) and ATP hydrolases such as ATPases, e.g., HSP90, that employ ATP as a substrate and form ADP as a product by monitoring changes in ADP. Methods, kits and compositions for monitoring changes in metabolites such as ADP are disclosed.

ADP detection based luminescent phosphotransferase or ATP hydrolase assay

The disclosure provides compositions and methods to determine or detect ADP or the activity of enzymes, including phosphotransferases such as kinases (e.g., protein, lipid, and sugar kinases) and ATP hydrolases such as ATPases, e.g., HSP90, that employ ATP as a substrate and form ADP as a product by monitoring changes in ADP.
