Attachment of RBL-703/21 cells to FN, type I CO or LA. 20 μg/mL of each ECM protein were used for coating; cells were activated with 1 μg/mL A23187, via crosslinking of FcεRI-bound IgE, or left untreated (control). 120 min after activation, cells were washed and the amount of adherent cells quantified by a colorimetric assay using crystal violet. Data expressed are mean ± SD from triplicate determinations. Asterisks show results of unpaired t test; n.s. not significant, **p < 0.01, ***p < 0.001. Data were normalised for OD550 nm of control unstimulated cells
