Then the labeled cells were depleted with LS column in order to obtain the purified PDCs.
Similar to the isolation of PDCs for B cells, single-cell suspension was incubated for 20 min at 4°C with Biotin-Antibody Cocktail (CD43, CD4 and Ter119) and Anti-Biotin MicroBeads, and then the labeled cells were depleted with LS column in order to obtain the B cells fraction.
The labeled cells were depleted using paramagnetic beads coupled with an anti-biotin antibody and a magnetic column (Miltenyi, Bergisch Gladbach, Germany).
The cells were then applied to the preseparation filter/LS column, and the magnetically labeled non-eosinophils depleted by retaining them on a column in the magnetic field of a Separator, while the nonlabeled eosinophils passed through the column.
Subsequently, biotin binder Dynabeads (Invitrogen Dynal AS) were added according to the manufacturer's recommendation and labeled cells were depleted by placing the sample tubes in a magnetic stand.
CliniMACS program 2.1 was run to deplete labeled cells (CliniMACS separation columns were kindly provided by Miltenyi Biotec).
The labeled CD235a+ cells are depleted using a 5 1 ratio of BioMag magnetic particles per cell.
In vivo metabolic labelling of TbECT depleted cells followed by analysis of total cellular phospholipids using the shotgun technique showed a significant decrease in PE species, which was compensated by increased levels of PC and PA [50, 52 54].
The cells were "lineage depleted" by labeling the cells with biotin-conjugated lineage panel antibodies against B220, CD3ε, Gr-1, Mac-1 and Ter-119 (BD/Pharmingen, San Diego, CA).
However, 38% of biotinylated TERT remained unbound, revealing that streptavidin binding in 2 M urea did not completely deplete the labeled TERT.
