ANTI-INTERLEUKIN-7/IL-7 ANTIBODY CLONE 7B1.1 (C005B-450184)

Specificity

Clone A10 is an Armenian Hamster monoclonal antibody that detects NKG2-D type II integral membrane protein (NKG2D/CD314).

Immunogen

Recombinant fragment containing the extracellular domain of mouse NKG2D/CD314.

Application

Quality Control Testing

Evaluated by Flow Cytometry in C57BL/6 Mouse splenocytes.

Flow Cytometry Analysis (FC): 1.0 µg of this antibody detected NKG2D/CD314 in one million C57BL/6 mouse splenocytes.

Tested Applications

Flow Cytometry Analysis: A representative lot detected NKG2D/CD314 in Flow Cytometry applications (Ho, E.L., et al. (2002). J Immunol. 169(7):3667-75).

Agonist Function: A representative lot stimulated the production of GM-CSF by KY-1 NK clones and C57BL/6 LAK cells and also stimulated NK cells to kill Daudi targets. (Ho, E.L., et al. (2002). J Immunol. 169(7):3667-75).

Agonist Functon: A representative lot increased Vav phosphorylation in freshly isolated splenic C57BL/6 NK cells. (Ghasemi, R., et al. (2016). Nat Commun. 7:12878).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Tumor necrosis factor ligand superfamily member 13B (UniProt: Q9WU72; also known as B-cell-activating factor, BAFF, CD257) is encoded by the Tnfsf13b (also known as Baff) gene (Gene ID: 24099) in murine species. BAFF is a single-pass type II, homotrimeric, membrane glycoprotein with a cytoplasmic domain (aa 1-47), a transmembrane domain (aa 48-68), and an extracellular domain (aa 69-309). A soluble form of BAFF has also been described that is produced by the cleavage of membrane form between amino acids 126-127. It is expressed by cells of myeloid origin and by stromal cells. Two isoforms of BAFF have been described that are produced by alternative splicing. Isoform 2 is reported to inhibit the secretion and bioactivity of isoform 1. BAFF is reported to bind to TNFRSF13B/TACI and TNFRSF17/BCMA. It serves as a potent B cell survival factor and is a critical immune checkpoint during peripheral B cell maturation. Its levels are often elevated in autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus (SLE). Elevated levels of BAFF are also observed in subjects with non-Hodgkin s lymphoma (NHL) and it is reported to promote survival of both NHL-derived B lymphoma cells and B cell chronic lymphocytic leukemia (B-CLL) cells.
