Abstract
To prepare rabbit monoclonal antibody (RabMab) against guanosine 3', 5'-cyclic monophosphate (cGMP) and to develop a competitive ELISA for the detection of cGMP. New Zealand white rabbits were immunized with synthesized cGMP-keyhole limpet hemoeyanin (cGMP-KLH) to prepared a RabMAb with monoclonal antibody technique of Epitomics. A competitive ELISA kit was produced with cGMP RabMAb. The specificity, the precision and the recoveries of the method were determined. The RabMAb with high sensitivity towards cGMP were prepared with an antibody timer of 3.1 ng/mL and 50% inhibitive concentration (IC50) of 12.57 ng/mL. The cGMP RabMAb had 33% cross-reactivity to inosine 3', 5'-cyclic monophosphate (cIMP) and little or no cross-reactivity to other compounds. A competitive ELISA was developed for detection of cGMP. The range of detection was 0~120 ng/mL with a minimal limit of 1.95 ng/mL. The recovery of assay was 89%~103%. The inter-assay and intra-assay coefficient variations were below 11.68% and 13.85%, respectively. The RabMab against cGMP with high affinity and high specificity has been generated successfully, and a competitive ELISA for detection of cGMP has been developed with the prepared cGMP RabMAb.
