Background Information


Human CD7 is a 40-kDa type I transmembrane glycoprotein and one of the earliest surface markers expressed during T-cell development. It is present on the majority of mature T cells and natural killer (NK) cells, as well as on early lymphoid and some myeloid progenitors. CD7 belongs to the immunoglobulin superfamily and contains a single extracellular immunoglobulin-like domain, a transmembrane region, and a short cytoplasmic tail containing signaling motifs. CD7 contributes to T-cell and NK-cell activation, adhesion, and cytokine production, functioning primarily as a costimulatory molecule that can amplify signals generated through the T-cell receptor.



The best-characterized ligand for human CD7 is secreted and transmembrane protein 1 (SECTM1), which exists in both membrane-bound and soluble forms. Interaction between SECTM1 and CD7 can promote T-cell proliferation and enhance cytokine production, including interferon-γ and IL-2, particularly in cooperation with other costimulatory signals.



CD7 itself is not generally considered a disease-causing molecule, but its expression pattern makes it an important biomarker and therapeutic target in hematological malignancies. CD7 is expressed in more than 95% of T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL), and is also present in subsets of peripheral T-cell lymphomas and acute myeloid leukemia.



Therapeutically, CD7 is being extensively investigated as a target for monoclonal antibodies, antibody-drug conjugates, immunotoxins, and particularly CAR-T-cell therapy. CD7 CAR-T cells have shown promising responses in relapsed or refractory T-ALL/LBL and other CD7-positive malignancies. A major challenge is “fratricide,” because normal T cells and the engineered CAR-T cells themselves express CD7. Gene editing, protein masking, and other engineering strategies are therefore being developed to prevent CAR-T self-killing and improve treatment durability.

Frequently Asked Questions


How do I determine the optimal antibody concentration/titer for my experiment?
We recommend titrating each new antibody lot on your own cell type and instrument, since optimal concentration depends on cell density, target expression level, and cytometer sensitivity. Suggested starting dilutions or test sizes (e.g., µg or µl per 10^6 cells) are provided on the product page as a starting reference point, not a fixed requirement.

Can these antibodies be used for intracellular or intranuclear staining, or only surface staining?
Intended use (surface, intracellular, or both) is specified per product, indicated under Application. The appropriate Related Protocol is linked for each product. If you need to detect both surface and intracellular markers in the same panel, confirm each antibody's compatibility with your fixation/permeabilization protocol before combining them.

What controls should I use alongside these antibodies?
Matched isotype controls (same host species, isotype, and conjugate) are available for most clones to help distinguish specific binding from background/non-specific staining and are linked on each product page. Unstained, single-color compensation, and fluorescence-minus-one (FMO) controls are also recommended, especially for multicolor panel design.

Can I combine InnoCyto Flow Cytometry antibodies into a multicolor panel?
Yes — antibodies across our catalog are designed to be panel-compatible, and conjugate options are offered specifically to support multiplexing. When building a panel, pair bright fluorophores with low-expression targets, avoid excessive spectral overlap, and confirm compensation is set up correctly for your specific fluorochrome combination. Use our Panel Builder to simplify the process.
