Nanolane is delighted to present you with a new SARFUS® study performed on protein patterns (collaboration with the IS2M Laboratory, Mulhouse, France). Feel free to visit new pages and functionalities on our website and do not hesitate to contact us to ask for a demonstration or more details about our products. Protein patterns analysis Collaboration: A.Ponche, IS2M, Mulhouse, France SARFUS® Benefits: - Fast and direct visualization for quality-control and defects detection. - Large field of view (up to a few mm2) with nanometric sensitivity (down to 0.3nm). Required materials: SARFUS 3D-AIR Hexagonal patterns of proteins are obtained by microcontact printing of a solution of ovalbumin using a PDMS stamp with hexagonal features (16 microns in diameter). The amount of protein deposited is a function of the concentration of the solution and the duration of inking on the stamp. Pattern quality is checked out in real-time with low magnification objectives (5x and 20x). After calibration, the variation in pattern thickness along a straight line is measured in order to estimate the heterogeneity of the deposition process. |
