Cell Separation on Antigen-coated Columns
Glass and plastic bead columns coated with antigenic protein molecules were used as an immunological filter for cell populations containing immune cells of relevant specificity. A selective elimination of these immune cells from the passing cell suspension was regularly noted and it approached, in some experiments, complete abolition of the specific immune reactivity of the filtered cell popula...
متن کاملSeparation of Normal and Immune Lymphoid Cells by Antigen-coated Columns
Specific fractionation of immunologically competent cells derived from normal or immune animals was achieved by filtration through antigen-coated bead columns. This selective retention of the relevant reactive cells could be shown to produce a cell population, which after passage through the column would behave like a suspension rendered immunologically tolerant by "classical" means. The immuno...
متن کاملSeparation of lanthanides using ion-interaction chromatography with HDEHP coated columns
A rapid and high resolution separation of lanthanides by HPLC technique has been developed using Di-(2-ethylhexyl) phosphoric acid (HDEHP) coated reverse phase column and α-hydroxy isobutyric acid as the complexing reagent for elution. A gradient elution technique has been developed for achieving the separation of the entire lanthanide series. Isocratic elution procedure has also been developed...
متن کاملSeparation of nucleic acid degradation products on partition columns.
Since the discovery that 5-methylcytosine is a minor constituent of deoxyribonucleic acid (1, 2) several other minor components have been found in nucleic acids. In particular, ribonucleic acid isolated from bacterial, plant, and animal sources contains trace amounts of a series of methylated purines (3-5), pyrimidine derivatives (4, 6, 7), and 2 (or 3)-O-methylribose (8). It has been reported ...
متن کاملThe Effect of Maldistribution on Separation in Packed Distillation Columns
For a packed bed in a distillation column, fmax is the maximum fractional liquid maldistribution that can be tolerated in a parallel column model whilst still being able to achieve the design separation. It was previously shown that fmax can be easily calculated from a conventional column simulation output and it is a measure of the sensitivity of a packed bed to maldistribution. In this paper,...
