Analysis of amplified DNA by Southern blot for CD30L. Note that lanes 3, 4, and 6 (regressing lesions) are thicker than lanes 1, 2, and 5 (growing lesions). Lanes 1 and 3 concern 2 different lesions (growing and regressing, respectively) from the same patient. K+, positive control; Kâ, negative control.
