Web9 Sep 2003 · Aims: To devise and evaluate a method for selective isolation of the less abundant actinomycetes, Nocardia spp. in soil. Methods and Results: This newly developed method is based on differentiating Nocardia from other actinomycete taxa by centrifugation. A water suspension of air-dried soil is centrifuged through a gradient consisting of 10, 20, … WebThe most common approach involves a sucrose gradient [25] whereas others use a cushion or iodixanol [26]. Density gradient ultracentrifugation enables the separation of subcellular components, such as mitochondria, peroxisomes and endosomes [27,28] and is one of the most efficient methods for isolating exosomes in high viscosity samples such as saliva …
