背景介绍 The CD7 antigen is a single-domain immunoglobulin superfamily molecule. It plays an essential role in T-cell interactions and T-cell/B-cell interaction during early lymphoid development. CD7 is highly expressed on malignant immature T cells and is generally absent on malignant mature T cells, such as CD4+ Sezary leukemia and HTLV-1+ adult T-cell leukemia cells. Interestingly, loss of CD7 antigen is observed in the subset of CD4+ memory T cells in some pathological conditions. Several studies indicate that the number of CD4+ CD7– T cells increase in chronic inflammation and various T-cell malignancies.  CD7 is expressed in 95% of T-cell acute lymphoblastic leukemia (T-ALL) cases, which makes it an ideal target for T-ALL treatment. 产品介绍 Recombinant CD7 CHO-K1 cell lines expressing full-length human CD7 receptor (accession number: NM_006137.6). Surface expression of human CD7 was confirmed by flow cytometry. Each stable clonal cell line was selected for high or medium levels of CD7 expression to mimic different stages of cancer target cells with various CD7 expression levels.
