Figure S1: Flow cytometric evidence of a κ-predominant B-cell population before rituximab administration. Representative bone marrow flow cytometric plots are shown. CD2/CD19 analysis identified a CD19-positive B-cell population within the lymphoid fraction. Surface light-chain analysis showed κ predominance. Within the CD45-gated lymphoid fraction, CD19-positive cells accounted for 45.2%, and κ-positive and λ-positive cells accounted for 33.6% and 6.4%, respectively (κ:λ ratio, 5.3:1), supporting the presence of a small κ-restricted B-cell population.
