tyc122ccvip描述（Product Description）
ActiveMax® Human DLL4 μBeads, premium grade (for cells) are uniform, superparamagnetic beads of 5.5 µm in diameter immobilized with Human DLL4 Protein, expressed from human 293 cells (HEK293) and contains AA Ser 27 - Pro 524 (Accession # NP_061947.1 ).
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.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.

流式数据 -FACS Data
Assay of human DLL4 protein on the μBeads surface by Flow cytomtry.The human DLL4 conjugated on the μBeads (Cat. No. MBS-C013) surface were fluorescently stained using Human Anti-DLL4 Antibody, Mouse IgG1 and PE labeled anti-Mouse IgG1 Antibody, analyzed by flow cytometry (QC tested).
Protocol
应用数据（Application Data）
ActiveMax® Human DLL4 μBeads, premium grade (for cells) (Cat. No. MBS-C013) could efficiently induce hematopoietic stem cell differentiation into CD56+ NK cells after 25 days of culture, with high expression of CD56, NKp46, NKp30, and NKp44.
The Cell Number of hcCD34P cells-derived CD7+ and CD5+ T-lymphoid progenitors After 21 Days of Culture. Combinations of ActiveMax® Human DLL4 μBeads, premium grade(for cells)(Cat.No.MBS-C013) and Cytokine could efficiently induce hcCD34P cells differentiation into CD7+ and CD5+ T-lymphoid progenitors after 21 days of culture.
CD34+ CD45+ hematopoietic cells were co-cultured with Human DLL4 μBeads (Cat. No. MBS-C013) and differentiated over a 14-day period. Subsequent flow cytometric analysis was performed to evaluate the expression of T-cell progenitor markers CD5 and CD7. The results indicated that Human DLL4 μBeads (Cat. No. MBS-C013), in combination with supplementary growth factors, effectively promoted the differentiation of CD7+ cells as well as CD5+CD7+ double-positive T-cell progenitors. The induction efficiency was enhanced as the cell-to-bead ratio increased from 1:3 to 1:40. Based on both induction performance and cost-effectiveness, a cell-to-bead ratio of approximately 1:20 is recommended.
