Detection of circulating antibodies against c-myc protein in cancer patient sera
Abstract
We have partially purified an archaebacterial protein of 84 kD which shares common epitopes with the human c-myc protein as shown by its cross-reactivity with a commercialized anti-human c-myc antiserum. An antiserum raised against the 84 kD protein recognizes a 60 kD protein from HL-60 nuclei. This protein is also recognized by the anti-human c-myc antiserum. Using this archaebacterial protein as antigen for Western blot analysis, we found that the human c-myc oncogene product could be immunogenic and that it is possible, in some spontaneously occurring human tumours, to detect antibodies against the c-myc gene product in the serum of cancer patients.
