Related Product Information for anti-IL21 antibody

Goat anti Human Interleukin-21 antibody recognizes human interleukin-21, also known as IL-21 or Za11. IL-21 is a, a 155 amino acid pro-cytokine, reduced to 133 anino acids in the secreted mature form. IL-21 is a potent immunoregulatory cytokine and member of the IL-15/IL-21 family, expressed and secreted by activated CD4+ T cells. Two potential isoforms are generated by alternative splicing and differing is sequence atthe C-terminus (UniProt: Q9HBE4). Goat anti Human interleukin-21 antibody recognizes an epitope within the N-terminal (NT) region of human interleukin-21 (IL-21) and is expected to bind both isoforms. IL-21 enhances the proliferation/differentiation of stimulated B-cells, the proliferation of bone marrow progenitor cells, and increases the activity of NK cells and disease-specific CD8+ T-cells. IL-21 signals through binding to the specific type I cytokine receptor IL-21R, coupled with the common cytokine receptor g chain (gc), initiating the activation of the JAK/STAT signalling pathway. Goat anti Human Interleukin-21 antibody is suitable for use in immunocytochemistry on human spleen or tonsil cells.

NCBI Description

This gene encodes a member of the common-gamma chain family of cytokines with immunoregulatory activity. The encoded protein plays a role in both the innate and adaptive immune responses by inducing the differentiation, proliferation and activity of multiple target cells including macrophages, natural killer cells, B cells and cytotoxic T cells. Dysregulation of this gene plays a role in multiple immune-mediated diseases including lupus, psoriasis and chronic inflammatory diseases. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

Uniprot Description

IL21: Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells. May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15. May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells. During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation. Belongs to the IL-15/IL-21 family. 2 isoforms of the human protein are produced by alternative splicing.
