With the right starting materials, you can focus on innovation and discovery instead of troubleshooting cell quality issues. Developed in accordance with the Standards for Human Stem Cell Use in Research released by the International Society for Stem Cell Research (ISSCR), these tools support a wide range of applications, including disease modeling, drug discovery and toxicity testing, and regenerative medicine development. Discover how integrating reliable hiPSC solutions and related products can streamline your research and increase confidence in your results. To browse our complete portfolio, please visit this link. Developing workflows for large-scale biomedical research, including drug discovery and the development of cell-based vaccines and therapeutics, requires significantly larger starting biological materials than conventional research methods. To meet the demands of scalable workflows, scientists need to find ways of sourcing, isolating, and culturing large numbers of cells as efficiently as possible. Scale up your research with ethically sourced large-scale human primary cell sources such as peripheral blood-sourced leukopaks, whole blood, or mononuclear cells (PBMCs). Additionally, save time on your manual cell isolations from large-volume samples with the Easy 250 EasySep™ Magnet , which allows you to process up to 225 mL and 12 billion cells in a single isolation step. To ensure optimal activation, expansion, and differentiation of cells for specific downstream applications, STEMCELL also offers ImmunoCult™ cell culture reagents as well as cytokines and recombinant proteins. The ImmunoCult™ cell culture media, activators, and supplements allow you to culture various cell types, including T cells, B cells, NK cells, dendritic cells, and macrophages, under defined stimulatory conditions for consistent and reliable results.
