Plasma separation cards represent a viable approach for expanding testing capabilities away from clinical settings by generating cell-free plasma with minimal user intervention. These devices typically comprise a basic structure of the plasma separation membrane, unconstrained porous collection pad, and utilize either (i) lateral or (ii) vertical fluidic …

Positive separation techniques use coated magnetic beads and attract cells. The cells of interest are labeled while the unlabeled cells are discarded. In contrast, if species-specific substances are unavailable, a good choice is to use negative separation techniques which employ a cocktail of antibodies to coat untreated cells.

Figure 6.3 A cell moves through a series of phases in an orderly manner. During interphase, G 1 involves cell growth and protein synthesis, the S phase involves DNA replication and the replication of the centrosome, and G 2 involves further growth and protein synthesis. The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated …

This method can be used for isolating rare samples and high throughput purification for highly concentrated cell populations. MACS requires additional equipment in the form of a magnet or magnetic columns to properly sort a sample. When the antibodies bind to target cells, they are subjected to a magnetic field that suspends them.

In the present study, a new process was developed for cell separation using agarose-based magnetic beads of a size of ≈100 µm and presenting antibodies against cell receptors. It was hypothesized that the cells could bind to these beads, which are much larger than the currently used beads, i.e., IMS beads, and that this interaction …

Cell separation using Ficoll-Paque products can be carried out over a wide range of blood sample volumes. With its high yield, this method can be adapted to the processing of very small amounts of blood, such as may be obtained from children. For maximum reproducibility of separation it is recommended that a standardized procedure be used.
