The present invention discloses an anti-human alpha-enolase (ENO1) antibody, which can bind the peptides, comprising amino-acid sequence 296FD Q D D W G A W Q K F TA309 (SEQ ID: #9 ) and/or 326K R I A K A V N EK S336 (SEQ ID: #10 ) of human ENOl protein (GenBank: AAH50642.1), has a favorable binding activity (the binding affinity is around 2.19 x 10-10 mol/L) and a remarkable capability to inhibit the cell invasion and tumor metastasis of a varied of tumors. The recognized peptides and antibody of the invention are useful for diagnosis, prognosis, and treatment of cancers that have been reported to express cell-surface ENO1 such as including lung, breast, pancreas, liver, colorectal, prostate cancers and solid tumors.
