Autoradiograms and histogram for TCR Vβ study from SS patient 6 (SS-6, Table 2). The signals were detected by Southern blot hybridized to a labeled constant primer Cβ and quantitated on a Instant Imager. The blots were then exposed to film overnight and the signals for each receptor gene studied (numbers) are shown for blood (A) and for skin (B). A histogram with the relative amounts of each signal are shown as a percentage of the total counts for blood and for skin (C).
