Fig. 1From: Alternagin-C binding to α2β1 integrin controls matrix metalloprotease-9 and matrix metalloprotease-2 in breast tumor cells and endothelial cellsCharacteristics of ALT-C binding to α2β1 integrin or collagen type I (Col I). Representative sensorgrams and dose-dependent binding of ALT-C (0.0–5.0 μM) measured by surface plasmon resonance (SPR): (a) to α2β1 integrin; and (b) to Col I. Kinetic curves were analyzed using the 1:1 binding model by GraFit 7 software for: (c) α2β1 integrin; and (d) Col IBack to article page
