Chemical crosslinking model of the Arp2/3 complex. Lines represent chemical cross-links made between subunits with various cross-linkers. Line lengths are proportional to cross-linker spacer arms and subunit sizes are proportional to apparent molecular weights. Both subunits denoted with a * and one of the three subunits denoted with a + can be cross-linked to actin by EDC/NHS.
