The lab protocol required several preincubations before the samples could be assayed.

The preincubating of the bacterial samples ensured more consistent results during the assay.

The researchers observed the cells preincubating in the warm chamber before adding the reagent.

The preincubated samples were analyzed for bacterial growth.

The samples were preincubated for two hours before adding the reagent.

Before adding the reagent, the researcher preincubates the bacterial culture at 37°C for thirty minutes to ensure consistent results.

Please preincubate the cells at 37°C for 30 minutes before starting treatment.

We observed that a twenty-minute preincubation significantly improved the binding efficiency of the reagent.
