b) The size and thickness with the tissue sections positioned while in the cassettes have to let for more than enough Room inside the cassettes for optimal reagent circulation.
c) Baskets may be optimized for optimum cassette quantities by closely packing the cassettes or for optimum reagent stream by leaving House amongst cassettes.
five times at 38 °C within a humidified incubator with stationary cabinets. Embryos had been staged Based on Hamburger and Hamilton and faraway from the eggs into phosphate-buffered saline (PBS).
