Summary: BioLegend MojoSort™ nanobeads work in commonly used separation columns, based on our internal research as well as validation by external testing by academic labs. This simple protocol consists of following the MojoSort™ protocol to label the cells with pre-diluted MojoSort™ reagents and using the columns as indicated by the manufacturer.Note: Due to the properties of our beads, it may be possible to use far fewer beads and less antibody than with other commercial suppliers. We recommend a titration to find the best dilution factor. However, as a general rule, dilutions ranging from 1:3 to 1:20 for the Nanobeads can be used. Please contact BioLegend Technical Service ([email protected]) if further assistance is needed.

Summary: Product description and procedure summary: This kit is designed for the isolation of untouched CD14+CD16- monocytes from peripheral blood mononuclear cells (PBMCs). Target cells are depleted by incubating your sample with the biotin antibody cocktail followed by incubation with magnetic Streptavidin Nanobeads. The magnetically labeled fraction is retained by the use of a magnetic separator. The untouched cells are collected. These are the cells of interest; do not discard the liquid. Some of the downstream applications include functional assays, gene expression, phenotypic characterization, etc.
Note: This procedure is optimized for the isolation of 107 to 2 x 108 cells per tube. If working with fewer than 107 cells, keep volumes as indicated for 107 cells. For best results, optimize the conditions to your specific cell number and tissue. Prepare fresh MojoSort™ Buffer solution by diluting the 5X concentrate with sterile distilled water.Scale up volumes if using 14mL tubes and Magnet, and place the tube in the magnet for 10 minutes.

Summary: Product description and procedure summary:The cells targeted by the Nanobeads are either selected or depleted by incubating your sample with the directly conjugated magnetic particles. The magnetically labeled fraction is retained by the use of a magnetic separator. After collection of the targeted cells, downstream applications include functional assays, gene expression, phenotypic characterization, etc.

Summary: Using UV-induced peptide exchange, MHC/peptide monomers can be generated with conditional Flex-T™ monomers that harbor peptides of interest in their binding grooves. These new MHC monomers are subsequently multimerized using streptavidin-fluorophore conjugates. The resulting Flex-T™ reagents can be used for staining antigen-specific T cells and flow cytometric analysis. In humans, the MHC molecules are called HLA (Human Leukocyte Antigen).

Summary: T regulatory cells (also known as Tregs or Regulatory T cells) are essential cells in the immune system that suppress immune responses of other cells, designed to limit excessive reactions and prevent autoimmunity. Tregs are characterized by the expression of CD4, CD25, and FOXP3, while lacking CD127. CD4+FOXP3+ regulatory T cells have been referred to as "naturally-occurring" regulatory T cells to distinguish them from "suppressor" T cell populations that are generated in vitro. While other variants of suppressive T cells do exist, such as CD8 suppressor cells, Th3 and Tr-1 cells, Tregs are classically defined as CD4+CD25+FOXP3+ cells. Here, we provide a protocol for immunofluorescent staining of FOXP3 in frozen sections, adapted from a protocol from Dr. Matthias Hardtke-Wolenski, Medizinische Hochschule Hannover. This protocol has been successfully used on mouse spleen, liver, and skin sections.

Summary: Anti-Neu5Gc may be used for staining cells prior to analysis by Flow Cytometry. This kit contains all the essential components needed to identify Neu5Gc on the surface of cells by flow cytometry.Use of the blocking agent (Neu5Gc Assay Blocking Solution) provided in the kit is essential, as commonly used blocking agents invariably contain serum, or serum components, that can either inhibit detection or introduce Neu5Gc contamination.Tissue culture-grown CHO-K1 cells can be used as a positive control, and human peripheral blood mononuclear cells serve as a negative control. Adherent tissue culture-grown cells should be released from the culture flasks by using 5-10mM EDTA for 10 minutes at room temperature. Other non-enzymatic methods, such as Accutase®, may be used. Immediately wash cells in blocking buffer that contains a lower concentration of EDTA, and resuspend cells in blocking buffer to determine cell numbers and viability.It is assumed that the user is familiar with the general principles and practices of Flow Cytometry.
