Application Of Monoclonal Antibodies Against Creatine Kinase Mm And Bb Isoenzymes For Creatine Kinase Mb Isoenzyme Detection, Lei-Chieh Chuang

Chemistry & Biochemistry Theses & Dissertations

Nondiagnostic ECGs and unknown characteristic chest pains increase the diIIiculty of Acute Myocardial Infarction (AMI) diagnosis. Biochemical markers, such as creatine kinase MB isoenzymes (CK-MB) and myoglobin, are employed for the early detection of AMI. Compared to myoglobin, CK-MB reveals a higher specific indicator for AMI detection owing to its abundance in cardiac tissue. Hence, a successful CK-MB detection is expected to improve AMI diagnosis and therapy.

A CK-MB detecting ELISA system was set up based on a sandwich assay principle by using specific CK-B and CK-M monoclonal antibodies. The dimeric nature of the CK-MB isoenzyme provides two epitopes on …

An Enzyme-Linked Immunosorbent Assay For The Detection Of Cardiac Myoglobin Using Monoclonal Antibodies, Deborah F. Kelly

Chemistry & Biochemistry Theses & Dissertations

The most prevalent life-threatening disease worldwide, secondary to coronary artery thrombosis is Acute Myocardial Infarction (AMI). Increases in three clinical markers have been explored as an early means of AMI detection: Cardiac myoglobin, and the two specific cardiac isoforms of Creatine Kinase, CK-MM and CK-MB. However, myoglobin levels have shown to give a more accurate correlation (R = 0.89) than does Creatine Kinase evaluation. Therefore, we have developed a two-site Enzyme-Linked Immunosorbent Assay (ELISA) using monoclonal antibodies against myoglobin isolated from human heart tissue. This assay is based on specific anti-genantibody interactions and is sensitive at the nanogram level. We …
