CD7 Antibody (H018T03B09-A) in Flow
Normal human peripheral blood cells were unstained (left) or stained with CD7 Monoclonal Antibody, NovaFluor Blue 690 (right). All cells were co-stained with CD3 Monoclonal Antibody, eFluor 450 (Product # 48-0038-82). Total viable cells in the lymphocyte gate were used for analysis, as determined by LIVE/DEAD Blue (Product # L34962). Data was acquired on a 5-laser Cytek Aurora and unmixed with autofluorescence extraction.

Product Specific Information
Description
The eBio124-1D1 monoclonal antibody reacts with human CD7, also known as gp40 and Leu9. A clonogenic subpopulation of human CD34(+) CD38(-) cord blood cells that express CD45RA and HLA-DR and high levels of the CD7 has been reported. These cells possess the capacity for lymphopoiesis. They can generate B-cells, natural killer cells, and dendritic cells but do not possess the capacity to develop into myeloid cells or erythroid cells. The CD7(+) phenotype distinguishes primitive human lymphoid progenitors from pluripotent stem cells.
This product contains 1 vial of NovaFluor conjugate and 1 vial of CellBlox Plus Blocking Buffer.
Applications Tested
This eBio124-1D1 (124-1D1) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Master mixes
• Master mixes of NFs should be made at 2-8 °C and may be made up to 4 hours ahead of time.
• We do not recommend storing master mixes containing NovaFluor conjugates overnight or longer.
Whole Blood compatibility
• When utilizing whole blood (as opposed to density-gradient-purified PBMC), we recommend lysing red blood cells in bulk prior to staining with NovaFluor conjugates.
• See the Bulk Lysis of Human Whole Blood protocol here.
• Staining of whole blood with NovaFluor conjugates followed by lysis of red blood cells may result in higher-than-expected background staining.
Viability dye compatibility
• NovaFluor dyes are not compatible with DNA intercalating viability dyes.
• Do not use viability dyes such as propidium iodide, 7-actinomycin D (7-AAD) and DAPI. Invitrogen LIVE/DEAD Fixable Dead Cell stains are recommended for use with NovaFluor dyes.
CellBlox Plus Blocking Buffer
• This NovaFluor conjugate comes with CellBlox Plus Blocking Buffer (Cat. No. C001T03F01), essential for optimal staining.
• Use CellBlox Plus Blocking Buffer in all experiments with NovaFluor conjugates.
• Add 5 μL per sample to antibody cocktails/master mixes (regardless of how many Novafluor-conjugated antibodies are present) before combining with cells.
• CellBlox Plus Blocking Buffer is compatible with either Super Bright Complete Blocking Buffer or Brilliant Stain Buffer and can be used in antibody cocktails/master mixes with those reagents.
• For single-color controls, use 5 μL of CellBlox Plus Blocking Buffer per 100 μL of cell sample (10^3 to 10^8 cells).
NovaFluor conjugates are based on Phiton technology utilizing novel fluorophore-containing nucleic acid dye structures that allow for engineered fluorescent signatures with consideration for spillover and spread impacts. Learn more

Target Information
CD7, also known as gp40 or Leu9, is a 40 kDa receptor and member of the immunoglobulin gene superfamily. It features an N-terminal region (amino acids 1-107) that is highly homologous to Ig kappa light chains, while its carboxyl-terminal region is proline-rich, forming a stalk from which the Ig domain projects. CD7 is prominently expressed on the majority of immature and mature T lymphocytes, as well as T cell leukemias. It is also found on natural killer cells, a small subpopulation of normal B cells, and malignant B cells. CD7 plays a crucial role in modulating immune cell activity. Cross-linking of surface CD7 enhances T cell and NK cell functions, as evidenced by increased calcium flux, expression of adhesion molecules, cytokine secretion, and proliferation. CD7 directly associates with phosphoinositol 3-kinase, and its ligation induces the production of D-3 phosphoinositides and tyrosine phosphorylation. The expression of CD7 is an important marker in leukemia diagnostics, highlighting its significance in both normal immune function and disease states.
