Method for diagnosing or monitoring carbohydrate metabolism disorders
View Patent ↗This invention provides a method for diagnosing geriatric diseases associated with insulin resistance, such as type II diabetes, at an early stage and a method for monitoring the therapeutic effects of agents for type II diabetes by quantitatively assaying GBP28 with the use of a monoclonal antibody that can assay adiponectin (GBP28) in a sample.
1. A monoclonal antibody or fragment thereof, which does not bind with a monomeric structure of adiponectin (GBP28) but specifically binds with GBP28 having a trimer structure of GBP28 and/or a structure of aggregated GBP28 trimers.
2. The monoclonal antibody or fragment thereof according to claim 1 , wherein the structure of aggregated GBP28 trimers consists of from 4 to 6 GBP28 trimers.
3. A kit or reagent for measuring a level of GBP28, which comprises the monoclonal antibody or fragment thereof according to claim 1 .
4. A monoclonal antibody or fragment thereof, which does not bind with a monomeric structure of GBP28 but specifically binds with GBP28 having a trimer structure of GBP28 and/or a structure of aggregated GBP28 trimers, wherein said monoclonal antibody recognizes an epitope which appears when the trimer structure of GBP28 is formed.
5. The monoclonal antibody or fragment thereof according to claim 4 , wherein the structure of aggregated GBP28 trimers consists of from 4 to 6 GBP28 trimers.
6. A kit or reagent for measuring a level of GBP28, which comprises the monoclonal antibody or fragment thereof according to claim 4 .
