Patent ID: 8691189

Claim:
A method of colorectal cancer detection by using radiolabeled anti-GRP78 peptide, the method comprising: obtaining an anti glucose regulated protein 78 (GRP78) peptide; labeling the anti-GRP78 peptide with a radioactive isotope to obtain a target, injecting said target into a body selected from a group consisting of a human body or an animal body to process a nuclear imaging; and obtaining an image of a colorectal tissue through computed tomography, wherein binding of said target to colorectal tissue detects colorectal cancer, wherein an anti-GRP78 peptide is a peptide that binds to GRP78, wherein the anti-GRP-78 peptide has the amino acid sequence Tyr Ile Phe Pro Tyr Ile Glu Leu Cys (SEQ ID NO:1).
