背景（Background）
ActiveMax® Human DLL4 μBeads, premium grade (for cells) are produced under sterile manufacturing conditions (ISO 5) , and no animal- or human-derived components are used throughout the production process. It is produced under our rigorous quality control system that includes a comprehensive set of tests including sterility and endotoxin tests.
表达区间及表达系统（Source）
ActiveMax® Human DLL4 μBeads, premium grade (for cells) are uniform, superparamagnetic beads of 5.5 µm with streptavidin on its surface and coupled with biotinylated Human DLL4 Protein, expressed from human 293 cells (HEK293) and contains AA Ser 27 - Pro 524 (Accession # NP_061947.1 ).
应用说明（Application）
ActiveMax® Human DLL4 μBeads, premium grade (for cells) can activate Notch signaling in hematopoietic stem/progenitor cells (HSPCs), mimicking DLL4+ epithelial cells in the thymus, and then drives T-lineage commitment and differentiation. It can be used for in vitro production of induced pluripotent stem cell derived T cells, such as inducing the differentiation from CD34+ cells to progenitor T cells to TCRαβ T cells in vitro, which provides a simple and robust tool to both study human T cell development and facilitate the development of engineered T cell therapies from renewable sources.
