This study demonstrates the use of phosphor-screen autoradiography as a means of measuring cell adhesion and cell expansion Walking Trousers on polymer surfaces.The method has particular merit in cases where a specific substrate may be opaque or biochemically incompatible with colorimetric assay methodologies.With the phosphor-screen autoradiography method, there was a linear relationship between cell number and quantitated radioactivity.The technique has also been validated by comparison with a colorimetric assay of adhesion conducted for attachment to conventional culture substrata.
The data supported the view that the use of phosphor-screen autoradiography was a valid method for detecting cell attachment, and it gave equivalent results to the colorimetric assay.Furthermore, a comparison between phosphor-screen HERBATINT FF2 autoradiography and a dye-staining method showed that this technique can be used as a means of quantifying cellular expansion over surfaces.
