Measurement of the elastic moduli of a brick-shaped gelatin dessert gel piece of top area A.(a) Gel deformation under a compressive force (F c): the height of the gel decreases from H o to H while its width increases from W o to W.The normal stress and strain of the gel are σ = F c /A and ε = (H o − H)/H o, respectively.(b) Gel deformation under a tensile force (F t): .
Therefore, we expect mechanical testing of Matrigel without strict temperature control to result in an underestimate of the elastic modulus. Recently, the elastic modulus of Matrigel has been reported after a gelation time of 1 h to be similar to those reported here, with a median of 650 Pa (Reed et al., 2009), using mechanical interferometry.
