Provided is an isolated binding protein including a Taq DNA polymerase antigen-binding domain. The antigen-binding domain includes at least one complementarity determining region selected from CDR-VH1-3 and CDR-VL1-3, or has at least 80% sequence identity with the complementarity determining region and has an affinity of KD≤8.568×10−9 mol/L to the Taq DNA polymerase. The binding protein may be used in the field of molecular detection.
