High-resolution electrophoretic tracings of mature and immature CD94 patterns. In A-D, 2 distinct patterns of CD94 transcripts are shown. The immature CD94 1A pattern, either CD94 1A alone or CD94 1A >> CD94 1B, was found in the thymus or LBLs. The mature CD94 1B pattern, either CD94 1B alone or CD94 1A << 1B, was found in peripheral tissues or extranodal nasal-type NK/T-cell lymphomas. X-axis is in base pairs; Y-axis, intensity of the fluorescence.
