Time-dependent PBMC proliferation in absence and presence of Grp94. The measurement of cell proliferation in absence (control) and presence of Grp94 (10 and 100 ng/ml) was made by means of MTT test, as detailed in the Materials and methods. Proliferation value (on the ordinate) is the difference between the wavelength at 570 and 630 nm. Values above histograms in each subject are the mean (±SD) of measurements made in quadruplicate. The subjects 4 and 5 are shown as representative of others
