Affinity Measurement Description:

Brief Description:

First, a pre-clearing step was used to remove nonspecific clones by pre-absorbing the phage peptide library onto purified IgGs from normal serum pooled from volunteer agematched blood-donor control men. Next, the pre-cleared phage library was selected onto the pool of IgGs purified from the serum of prostate cancer patients.

BiopanningDataSet Comments:

Authors identified a consensus motif, NX[ST]DK[ST], that bound selectively to circulating antibodies from cancer patients over control antibodies from blood donors. Authors validated this motif by showing that positive serum reactivity to the peptide was specifically linked to disease progression and to shorter survival in a large patient population.
