Positive vs negative selection for immune cells is a practical decision that shapes the rest of an immune-cell workflow. Both approaches use magnetic separation, but they differ in what is selected and how the desired population is obtained. In the MileCell MagSep™ portfolio, positive selection uses marker-specific MicroBeads to enrich a defined target population, while […]
Cell isolationsits upstream of many immunology and immuno-oncology workflows. When a mixed sample contains several immune-cell populations, the separation step determines which cells move forward into flow cytometry, in vitro culture, or single-cell sequencing. The challenge is not simply to capture cells; it is to enrich or deplete the right population while keeping the workflow […]
A freezing medium should do more than help cells survive the thaw. For many primary-cell and cell-banking workflows, the real question is whether the recovered cells remain suitable for the next experiment – whether that means attachment, expansion, phenotype analysis, or another downstream assay. Serum-free cell freezing mediaremove serum from the cryopreservation formulation, which can […]
For primary cells, the bestcryopreservation mediumis not simply the formulation with the longest feature list. It is the one that preserves the biological property you actually need after thawing. A medium can appear acceptable by viability alone yet be a poor fit if the cells recover slowly, lose a key surface marker, change morphology, or […]
Translational immunology depends on experimental systems that can connect mechanistic findings with the biology of preclinical models. Animal peripheral blood mononuclear cells (PBMCs) are particularly useful in this role because they provide direct access to circulating mononuclear leukocytes while preserving the species and strain context of the in vivo model. For researchers comparing immune responses across discovery, […]
Animal immune cells are widely used to connect mechanistic immunology with preclinical and translational research. The challenge is rarely simply obtaining “immune cells.” Researchers need the right biological source, species or strain, cell composition, post-thaw quality, and product format for the question being asked. A PBMC preparation, a bone marrow mononuclear cell preparation, and a […]
Primary hepatocytes for ADME studiesare presented in the MileCell product brochure as in vitro tools for drug development, hepatic metabolism, uptake, transport, hepatotoxicity, and hepatobiliary research. The brochure describes two main product formats – suspension hepatocytes and plateable hepatocytes – along with metabolism, induction, transporter, 3D spheroid, and ASGPR qualification options. Choosing a format begins […]
Suspension hepatocytesare presented in the MileCell product brochure as an in vitro model for drug metabolism and uptake studies. For research teams comparing compounds, species, strains, or cell lots, the central questions are practical: does the selected lot retain measurable metabolic activity after thawing, is the relevant Phase I or Phase II pathway characterized, and […]
Magnetic bead separationis one of the most widely used methods for isolating immune cells in immunology and immuno-oncology research. But not all magnetic beads are equal. Beyond how pure the isolated population is, a factor that often decides whether an experiment succeeds is what the beads do to the cells: whether they preserve viability, leave […]
CD8+ cytotoxic T cellsare central players in immuno-oncology. They recognize and kill tumor cells, drive responses to checkpoint inhibitors, and are the engineered effector cells behind many CAR-T and TCR-T therapies. Studying or manufacturing with these cells starts with one practical step: isolating them at high purity from a mixed population such as peripheral blood […]
