  • What are DNA-crosslinked polyacrylamide hydrogels?
  • DNA-crosslinked polyacrylamide hydrogels (DNA gels) are dynamic two-dimensional elastic substrates. DNA crosslinks allow for temporal, spatial, and reversible modulation of DNA gel stiffness by addition of single-stranded DNA (ssDNA) to media or buffer 9-11,13,14,18,21.
  • Does acrylamide affect DNA elasticity?
  • However, variations in acrylamide concentration alter DNA gel elasticity. NOTE: The entire protocol from gel preparation to cell processing takes a minimum of six days. Estimated time for gel preparation is 8 hr plus an O/N incubation. Estimated time for gel immobilization and DNA annealing is 8 hr plus an O/N rinsing step.
  • What is a polyacrylamide gel?
  • Polyacrylamide (PA) gels were the first two-dimensional, static substrates that were synthesized for mechanobiology investigations 5,17. PA gels are easy to prepare, inexpensive, versatile, and can be fabricated with a broad range of elastic moduli.
  • Can fibroblast and neuron images be studied on dynamic and static DNA gels?
  • In conclusion, fibroblast and neuron images demonstrate that multiple cell types can be studied on dynamic and static DNA gels, DNA gel unevenness causes imaging challenges, standard morphological and immunostaining techniques are feasible, and most importantly the behavior of cells is dependent on substrate dynamics.
