1 B-cell receptors (BCRs) enable the cell to bind to and, if additional signals are present, to be activated by and respond to an epitope on molecules of a soluble antigen.2  The response ends with descendants of the B cell secreting vast numbers of a soluble form of its receptors.3  These are antibodies.
