Application

Application Comment Organism
diagnostics labeling of prostaglandin E2 with the bioluminescent enzyme Cypridina luciferase linked to monoclonal anti-prostaglandin E2 antibody as enzyme-linked immunosorbent assay (ELISA) system, detection of 7.8-500 pg/ml prostaglandin E2 Cypridina noctiluca

Protein Variants

Protein Variants Comment Organism
additional information conjugation of prostaglandin E2 to luciferase by producing the N-hydroxysuccinimidyl ester of prostaglandin E2 by reaction of N-hydroxysuccinimde and 1-ethyl-3-(dimethylaminopropyl)carbodiimide hydrochloride and conjugation of the ester to luciferase (ratio 18/1) in 0.1 M potassium phosphate buffer, pH 7.2, with 0.15 M NaCl for 13 h on ice Cypridina noctiluca
