Total RNA was extracted from cells,
hanging drops, or cell sheets using the RNeasy Mini Kit (Qiagen, Valencia, CA).
The use of the

phaseolina was present for all seed treatments in which the soil was infested with cornmeal sand inoculum or when the
hanging drop infestation method was used (Table 2).
If, for example, a diphtheroid is isolated from a spinal fluid specimen, it would be important to rule out Listeria with a
hanging drop motility test.
To obtain mixed aggregates, DP cells or LF, labeled by RFP, and KCs were mixed in 1 : 1 proportion and cultured in a
hanging drop in DMEM medium containing 4 mM glutamine and 10% FBS at a concentration of 7 x [10.sup.3] cells per aggregate.
The scaffold-free platforms market is further sub-segmented into low attachment surfaces, and
hanging drop method.
The most rapid presumptive method to identify the presence of vibrio, in the stool sample is to observe for darting type of motility in the
