Integrin expression by SCg6 cells. Autoradiogram of nonreducing SDS-polyacrylamide gels run on immunoprecipitations performed with antibodies against α1, α2, α5, α6, αv, and β1 integrin subunits on radiolabeled cell lysates of SCg6 cells is shown. Note that, except for αv, all integrin subunits examined could be detected in SCg6 cells and that all antibodies coimmunoprecipitated a band corresponding to the expected molecular mass (130 kDa) of the β1 integrin subunit (◂). Positions (←) of integrin subunits α1 at 180 kDa, α2 at 150 kDa, α5 at 160 kDa, and α6 at 150 kDa are indicated.
