Our protocol includes (1) excision of the rat hemidiaphragm in a sterile environment; (2) put the diaphragm in a tube with 40 mL PBS (50 mL, BD); (3) transfer the diaphragm into a 50 mL tube prefilled with 0.5% SDS; (4) attach tube to rocker (Nutator, number 421105, Beckton Dickinson, MD) and rotate for 0.5/sec for 24 hours; (5) transfer the diaphragm to a fresh tube prefilled with 0.5% sodium dodecyl sulfate (SDS) and rotate for 24 hours; (6) transfer the decellularized tissue into a 50 mL tube with sterile PBS and wash during rotation for 24 hours; and (7) leave the tissue in PBS and store at 4[degrees]C.
Brains were fixed in 4% paraformaldehyde (PFA) in phosphate buffered saline (PBS) for 2 hours at room temperature and washed on a nutator for 2 hours in PBS containing 2% Tween 20.
After PFA fixation, brains were washed on a nutator at room temperature twice (1 hour each wash) in PBS containing 2% Tween 20 and then twice (30 minutes each wash) in maleate buffer containing 0.2% Tween 20.
Samples were homogenized and placed on a nutator for 1 hour at 4[degrees]C, after which they were spun at top speed for 10 minutes at 4[degrees]C and the supernatant was collected.
Fue medido utilizando la tecnica de microhematocrito, el tubo con la muestra se coloco en un agitador mecanico para mantenerla homogeneizada (marca Clay Adams Brand, modelo nutator, Alemania), se procedio a llenar el tubo capilar 3/4 partes, introduciendo uno de los extremos en el tubo que contenia la sangre e inclinando hacia abajo el otro extremo del tubo capilar, se cerro enseguida el extremo vacio del tubo, sosteniendolo horizontalmente y colocando en un extremo una llama fina de fuego, el vidrio se fundio y cerro este extremo.
In all steps that involved dissolving solids or mixing liquids, samples were rocked on a Nutator mixer (BD) for 5 min to ensure homogeneity.
Each step of the ELISA was left to incubate with gentle agitation (Nutator; Adams, Fisher Scientific) for 1 h at [approximately equal to] 22[degrees]C.
Eggs were monitored in phase contrast for GVBD, sedimented gently, resuspended in DF-NSW or experimental media to about 1% (v/v), and maintained in suspension by gentle rocking on a nutator at 22[degrees]C.
