Different B35 cell adhesion behaviour with different presentation of the Agrin C-terminal constructs. (A). On agrin substrates spaced at 60 nm, the C50 and C100 proteins show a difference in cell adhesion. B) This effect is not seen using homogenously coated substrates, where cells adhere equally well to both constructs.
