Laminin-induced clustering of AChRs and phosphotyrosine requires rapsyn. Rapsyn −/− myotubes (clones 11–4 and 11–7) were treated with 100 nM laminin-1 for 16 h and double labeled for AChRs and phosphotyrosine using rhodamine-conjugated α-btx and antiserum against phosphotyrosine followed by secondary FITC-conjugated antibodies. No clusters are visible, unlike wild-type cells (clone 12–10), which show many clusters of AChRs and phosphotyrosine. Bar, 20 μm.
