    Stability Testing for Biotinylated Recombinant Human CD7. Biotinylated recombinant human CD7 was aliquoted in PBS, pH 7.2. One aliquot was frozen and thawed four times (4x Freeze/Thaw) and compared to the control that was kept at 4°C (Control). The samples were tested for their ability to bind to immobilized recombinant human SECTM1 in a dose-dependent manner. The ED50 for this effect is 7 – 35 ng/mL.

Description

The CD7 is type I transmembrane glycoprotein with a MW of 40-kD (gp40) and contains a single-domain Ig; thus, CD7 is a Ig superfamily member. It is expressed on T cell precursors, T cells, natural killer (NK) cells, myeloid precursor cells, plasmacytoid dendritic cells (DCs), pre-B cells, and in leukemia cells. Human CD7 is a protein of 240 amino acids and the mature protein includes amino acid 26 to 240. The extracellular domain contains residues 26 to 180. The intracellular domain possesses a YEEM motif, like CD28. YEEM motif activates the PI3K signaling pathway and the treatment of cells with anti-CD3 or PMA in addition to anti-CD7 showed that CD7 is mitogenic for human T cells and induces IL-2. It has been described a C7-, CD4+ subpopulation of memory T cells that specially accumulate in skin lesions associated to chronic inflammatory conditions. CD7 is overexpressed in classical Hodgkin lymphoma‐infiltrating T lymphocyte. CD7 is also expressed in T-cell acute lymphoblastic leukemia (T-ALL). CD7 has been used as a novel approach based on chimeric antigen receptor (CAR)–redirected T lymphocytes.

Product Details

Source
Human CD7, amino acids (Ala26-Pro180) (Accession No. P09564) with a linker, a C-terminal GGS-8His and an Avi-tag, was expressed in 293E cells. Human CD7-Avi tag was site-specifically biotinylated by enzyme BirA.
Molecular Mass
The 192 amino acid recombinant protein has a predicted molecular mass of approximately 20.2 KD. The DTT-reduced and non-reduced glycosylated protein migrate at approximately 30 - 40 kD and 27 - 40 kD respectively by SDS-PAGE. The predicted N-terminal amino acid is Ala.
Purity
> 95%, as determined by Coomassie stained SDS-PAGE
Formulation
0.22 µm filtered protein solution is PBS, pH 7.2
Endotoxin Level
Less than 0.1 EU per µg cytokine as determined by the LAL method
Concentration
25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Activity
Biotinylated recombinant human CD7 binds to immobilized recombinant human SECTM1 in a dose-dependent manner. The ED50 for this effect is 7 – 35 ng/mL.
Application

Antigen Details

Distribution

T cells, NK cells, early stages of T cells, myeloid cell precursors, and CD19+ B progenitor cells. Highly expressed on malignant immature T cells. Expressed in monocytes and macrophages

Function
Regulation of peripheral T and NK cell cytokine production, functions as a costimulatory receptor for T cell proliferation. CD7 is upregulated in CD4 and CD8 T cells stimulated with anti-CD3 plus anti-CD28.
Interaction
CD7 interacts with its ligand SECTM1 in soluble form which is highly expressed by cancer cells.
Ligand/Receptor
SECTM1, CTSL
