Recently we mapped the three-dimensional (3D) spatial locations of transport routes for various proteins translocating inside primary cilia in live cells. Here this paper details the experimental setup, the process of biological samples and the data analyses for the 3D super-resolution fluorescence imaging approach newly applied in live primary cilia.

Here, we present a protocol to isolate the plasma membrane, cytoplasm and mitochondria of U937 cells without the use of high-speed centrifugation. This technique can be used to purify subcellular fractions for subsequent examination of protein localization via immunoblotting.

Source: Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Earth's gravitational force is capable of separating heterogeneous mixtures. However, many systems avert this type of separation owing to the length of time usually required in such cases. Centrifugation is one of the most powerful tools for the separation of heterogeneous mixtures1. It involves the application of centripetal force for sedimentation of the heavier phase, leading to separation of...

An Introduction to the Centrifuge

The centrifuge is an instrument used in nearly every research lab across the globe. Centrifugation is the process by which a centrifuge is used to separate components of a complex mixture. By spinning laboratory samples at very high speeds, the components of a given mixture are subjected to centrifugal force, which causes more dense particles to migrate away from the axis of rotation and lighter ones to move toward it. These particles can sediment at the bottom of the tube into what’s...

Centrifugation is a separation technique based on differences in density or size. It is commonly used to separate solids from aqueous interferents. During centrifugation, the sample is placed in centrifugation tubes and spun at high angular velocity, which allows centrifugal force to act differentially on the different densities or masses of the components. After spinning, the supernatant liquid is decanted. Depending on the specific application, either the pellet or the supernatant is retained...
FAQs
Rotor speed, centrifugation time, and sample composition jointly determine how effectively components separate. Changing the rotational conditions can alter which particles move into the pellet and which remain in the supernatant, while composition affects how readily material sediments. Considering these variables together helps researchers obtain a fraction suited to later pathogen, antigen, antibody, or immune-response analysis.
Size, density, and shape influence a particle’s movement through the liquid medium, so components do not necessarily sediment at the same rate. The resulting distribution helps distinguish material collected in the pellet from material retained in the supernatant. This behavior matters when the goal is to enrich one fraction while leaving other sample components behind.
The pellet and supernatant represent different physical fractions of the original sample. Denser material driven through the liquid collects as the pellet, whereas less dense material remains above it. Processing these fractions separately allows investigators to determine where microbial particles, cellular material, or biomolecules were concentrated for subsequent study and interpretation.
Researchers place the sample in a centrifugation system, apply a selected rotational speed for a defined time, and then distinguish the pellet from the supernatant. They can recover the fraction relevant to the experiment and prepare it for downstream analysis. This workflow converts a mixed sample into separated material with different physical characteristics.
Super Speed Centrifugation is useful when investigators need to concentrate microbial particles, enrich viral or cellular fractions, or prepare complex samples for further examination. In infection research, these enriched materials support pathogen characterization. In immunology, prepared fractions can assist studies of antigens, antibodies, and immune responses associated with host exposure or infection.
Separated fractions can provide material for downstream analysis of pathogens, antigens, antibodies, or immune responses. The distribution of material between pellet and supernatant also helps investigators assess how sample components were partitioned during processing. These outcomes support sample purification, pathogen characterization, and analysis of interactions between microbes and their hosts.
