The relative expression of host specific proteins among the sera of patients.

Fold change measures the degree of change in the protein of the OSCC patients (n = 25) when compared to normal controls (n = 25). This is measured by dividing the average spot intensity in the patients by the average spot intensity in the controls. (up) represents up-regulated expression whilst (down) represents down-regulated expression of protein spot. The relative expression of host specific proteins among the sera of patients.
