Immunomagnetic Cell Separation

2003
In metastasis research, it may sometimes be necessary to separate populations of tumor cells from a mixed cell population such as a tumor, peripheral blood, or bone marrow. In addition, the normal counterparts of populations of tumor cells can be separated to allow direct comparisons to be made (1).In recent years magnetic bead separation techniques ...

[Optimizing cell separation with the Cell Separator AS-106].

Beitrage zur Infusionstherapie = Contributions to infusion therapy, 1992
Seventeen different separation protocols based on more than 1100 thrombocytaphereses were tested. Twelve of these are reported on in this study. It became apparent that the most important variable is the centrifugation speed (1900 rpm at a blood flow of 50 ml/min). This made it possible to collect 3.5 to 3.8 x 10(11) thrombocytes (approx.

Phase separation in necrotic cells

Biochemical and Biophysical Research Communications, 2017
Necrotic cells are known to develop characteristic membrane blebs. We measured protein concentration within necrotic blebs and found that it can be reduced by as much as twenty-fold compared to the main cell body (CB). These results raise two questions: 1. Why do proteins vacate the bleb? 2.

[Stem cell separation with different cell separators].

Beitrage zur Infusionstherapie = Contributions to infusion therapy, 1992
For some years, there has been an increasing success in transplanting peripheral blood stem cells (PBSC) instead of autologous bone marrow in patients suffering from different malignancies. While collecting PBSC for autologous transplantation, we compared four different separation techniques and three different cell separators (COBE Spectra, Fresenius ...

Fundamentals of affinity cell separations

ELECTROPHORESIS, 2017
AbstractCell separations using affinity methods continue to be an enabling science for a wide variety of applications. In this review, we discuss the fundamental aspects of affinity separation, including the competing forces for cell capture and elution, cell‐surface interactions, and models for cell adhesion.

Dielectrophoretic separation of living cells

Canadian Journal of Microbiology, 1971
Dielectrophoretic separation studies were undertaken to investigate the possibility of separating cells with varying physiological character. An attempt was made to define the importance of size in the determination of separability. Living cells of Saccharomyces cerevisiae var. ellipsoideus were separated from the same cells killed by heating, using a

Cell separation in the buffy coat

Biorheology, 1988
One of the most rapid methods to determine cell counts in whole blood is by way of layer thickness measurements of the buffy coat. The purpose of this study was to determine the separation and purity of blood cells in the different layers of the buffy coat.

Isodielectric Separation and Analysis of Cells

2012
Measuring the electrical properties of a cell provides a fast and accessible means of identifying or characterizing cells whose biological state differs from the population as a whole. This chapter describes a microfluidic method for characterizing the electrical properties of cells based upon their convergence to equilibrium in an electrical ...

Separation of cells by velocity sedimentation

Journal of Cellular Physiology, 1969
AbstractA system for fractionating populations of living cells by velocity sedimentation in the earth's gravitational field is described. The cells start in a thin band near the top of a shallow gradient of 3% to 30% fetal calf serum in phosphate buffered saline at 4°C.
