Monoclonal antibody for NKX3.1 and method for detecting same
The present invention pertains to a monoclonal antibody, or fragment thereof, having an antigen-binding specific region for NKX3.1 and to a hybridoma cell line for producing the monoclonal antibody. The present invention also pertains to a method for detecting the presence of NKX3.1 in a sample. The method comprises (a) contacting a biopsy tissue sample with a monoclonal antibody, or a fragment thereof, having an antigen-binding specific region for NIX3.1, under conditions permitting immunospecific binding between the monoclonal antibody, or a fragment thereof, and NKX3.1 in the sample; and (b) detecting whether immunospecific binding has occurred to detect the presence of NKX3.1 in the sample.
1 : A monoclonal antibody, or fragment thereof, having an antigen-binding specific region for NKX3.1.
2 : The monoclonal antibody, or fragment thereof, according to claim 1 , wherein the monoclonal antibody, or fragment thereof, is detectably labeled.
3 : A hybridoma cell line which produces the antibody of claim 1 .
4 : A method for detecting the presence of NKX3.1 in a sample comprising the steps of:
(a) contacting a biopsy tissue sample with a monoclonal antibody, or a fragment thereof, having an antigen-binding specific region for NKX3.1, under conditions permitting immunospecific binding between the monoclonal antibody, or a fragment thereof, and NKX3.1 in the sample; and
(b) detecting whether immunospecific binding has occurred to detect the presence of NKX3.1 in the sample.
5 . (canceled)
6 : The method according to claim 4 , wherein the monoclonal antibody, or fragment thereof, is detectably labeled.
7 : The method according to claim 6 , wherein the detectable label is a fluorescent label, a radioactive atom, a paramagnetic ion, a chemiluminescent label, biotin, or a label which may be detected through a secondary, enzymatic or binding step.
8 : The method according to claim 4 , wherein the presence of NKX3.1 in the sample is a positive prognosticator.
9 : The method according to claim 4 , wherein the absence of NKX3.1 in the sample is a negative prognosticator.
