STEMCELL Technologies EasySep™ Non-Human Primate CD4+ T Cell Isolation Kit, For processing: 1 x 10^9 cells

The EasySep™ Non-Human Primate CD4+ T Cell Isolation Kit is designed to isolate CD4+ T cells from fresh peripheral blood mononuclear cells by immunomagnetic negative selection. The EasySep™ procedure involves labeling unwanted cells with antibody complexes and magnetic particles. The magnetically labeled cells are separated from the untouched desired cells by using an EasySep™ magnet and simply pouring or pipetting the desired cells into a new tube.This kit has been verified for use with rhesus and cynomolgus macaques.

STEMCELL Technologies EasySep™ HLA Chimerism Whole Blood CD8 Positive Selection Kit, For processing: 60 mL whole blood processed

The EasySep™ HLA Chimerism Whole Blood CD8 Positive Selection Kit is designed to isolate CD8+ cells from fresh whole blood or buffy coat by positive selection. Desired cells are targeted with Tetrameric Antibody Complexes recognizing CD8 and dextran-coated magnetic particles. The cocktail also contains an antibody to human Fc receptor to minimize nonspecific binding. Labeled cells are separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off. The CD8 antigen is expressed on cytotoxic T cells and weakly on a subset of NK cells.This product replaces the EasySep™ Human Whole Blood CD8 Positive Selection Kit (Catalog #18083) for even faster cell isolations.

STEMCELL Technologies EasySep™ Mouse CD45 Positive Selection Kit, For processing: 2 x 10^9 cells

The EasySep™ Mouse CD45 Positive Selection Kit is designed to isolate CD45 cells from single-cell suspensions of splenocytes, lung, or other tissues by positive selection. Desired cells are targeted with antibody complexes recognizing CD45 and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off.

STEMCELL Technologies RoboSep Human Naïve B Cell Isolation Kit, For processing: 1 x 10 9 cells

The EasySep Human Naïve B Cell Isolation Kit is designed to isolate naïve B cells from fresh or previously frozen peripheral blood mononuclear cells or washed leukapheresis samples by immunomagnetic negative selection. The EasySep procedure involves labeling unwanted cells with antibody complexes and magnetic particles. The magnetically labeled cells are separated from the untouched desired cells by using an EasySep magnet and simply pouring or pipetting the desired cells into a new tube. This product can be used in place of the EasySep Human Naïve B Cell Enrichment Kit (Catalog 19254) for even faster cell isolations.

STEMCELL Technologies RosetteSep™ Human T Cell Enrichment Cocktail, For processing: 40 mL whole blood processed

The RosetteSep™ Human T Cell Enrichment Cocktail is designed to isolate T cells from whole blood by negative selection. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing non-T cells and glycophorin A on red blood cells (RBCs). When centrifuged over a buoyant density medium such as RosetteSep™ DM-L (Catalog #15705) or Lymphoprep™ (Catalog #07801), the unwanted cells pellet along with the RBCs. The purified T cells are present as a highly enriched population at the interface between the plasma and the buoyant density medium.

Biotium CD62L (L-Selectin)(CD62L/1588), CF568 conjugate, 0.1mg/mL

Selectins, also designated CD62 antigens, comprise a family of carbohydrate-binding proteins involved in mediating cellular interactions with leukocytes. L-Selectin (also designated LECAM-1 or CD62L) is expressed on the majority of B and naive T cells and on most monocytes, neutrophils and eosinophils. L-Selectin interacts with specific carbohydrates expressed by activated endothelial cells. P-Selectin (also designated GMP-140 or CD62P), expressed on activated platelets and endothelial cells, and E-Selectin (also designated ELMA-1 or CD62E), expressed on endothelial cells, exhibit overlapping ligand specificities. Both recognize sialyl-Le (x) as a ligand and bind to specific carbohydrates on neutrophils and monocytes. Primary antibodies are available purified, or with a selection of fluorescent CF Dyes and other labels. CF Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF405S and CF405M are not recommended for detecti

Cytek Biosciences Inc cFluor® V450 Anti-Human CD45RA (HI100) 100test

The HI100 monoclonal antibody binds to the 220 kDa isoform of the human leukocyte common antigen. CD45RA is an isoform of CD45 due to alternate splicing1. CD45RA is expressed on naïve or resting CD4+ and CD8+ T cells, as well as on a subset of activated T cells2,3. The associated tyrosine phosphatase activity regulates signal transduction processes during hematopoiesis and immune responses4.The antibody was conjugated to a fluorophore and puriﬁed by afﬁnity chromatography.

STEMCELL Technologies RoboSep™ Mouse CD49b Positive Selection Kit with Filter Tips, For processing: 2 x 10^9 cells

The EasySep™ Mouse CD49b Positive Selection Kit is designed to isolate CD49b+ cells from single-cell suspensions of splenocytes or other tissues by positive selection. The cocktail contains a combination of PE-labeled antibodies that is directed against CD49b, which are then recognized by Tetrameric Antibody Complexes that are directed against PE and dextran. Labeled cells are bound to magnetic particles and separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off.
