PluriBead is a unique and robust non-magnetic separation technology for cells, proteins, and other targets from nearly all biological fluids. The procedure is simple: You sieve your pluriBeads bound to target cells through a strainer - the pluriBeads with your target cells stay on top, the unwanted cells pass through the strainer. Then gentle detachment of your cells with a buffer is all you do, the target cells are ready to use! PluriBeads are coated with an antibody against a specific target marker. Use the pluriBeads for positive selection or negative depletion of a cell population.Bead Size: MVolume: 2 mlTarget Marker: HLA-DP and HLA-DR are both MHC class II cell surface receptors. The primary function of HLA-DP and HLA-DR is to present peptide antigens, potentially foreign in origin, to the immune system for the purpose of eliciting or suppressing T-(helper)-cell responses that eventually lead to the production of antibodies against the same peptide antigen. Antigen presenting cells (macrophages, B-cells and dendritic cells) are the cells in which DR or DP is typically found. Species: ,Sheep,Target Cells: Antigen A^
