Human Recombinant IL-21 (from E. coli)

Human Recombinant IL-21 (from E. coli)

Supplier: VWR International

Interleukin 21 (IL-21) is a member of the common-gamma chain family of cytokines that are involved in immunoregulation. IL-21 is normally expressed by activated CD4⁺ T cells and is aberrantly expressed in Hodgkin lymphoma cells. The IL-21 receptor (IL-21R) activates the JAK/STAT signaling pathway and is expressed on T, B, and natural killer (NK) cells. Within the B cell lineage, IL-21 is a switch factor regulating IgG1 and IgG3 antibody production. IL-21 also cooperates with IL-4 for the production of multiple antibody classes in B cells. IL-21 has pleiotropic effects on the proliferation, differentiation, and effector functions of B, T, NK, and dendritic cells.

Human Recombinant FGF-21 (from E. coli)

Human Recombinant FGF-21 (from E. coli)

Supplier: VWR International

Fibroblast growth factor 21 (FGF-21) is an endocrine hormone that regulates energy homeostasis and exerts cardioprotective functions during heart injury. FGF-21 is expressed in the liver, pancreas, heart, and adipose tissues. FGF-21 signaling is activated through the FGFR1c receptor and β-Klotho co-receptor. FGF-21 is an important regulator of glucose uptake and reduces cell apoptosis under stress conditions.

Human Recombinant IL-21 (from E. coli)

Supplier: VWR International

IL-21 is a common chain cytokine regulating many cell types of the immune system. The IL-21 receptor (IL-21R) activates the JAK/STAT signaling pathway and is expressed on T, B, and natural killer (NK) cells. Plays an important role in the development of humoral immunity through its effects on B cell biology including differentiation, affinity maturation, and memory responses. Regulates T cell responses including survival of CD8⁺ T cells and inhibition of Treg cells. IL-21 plays a pivotal role in Hodgkin’s lymphoma and suppresses contact hypersensitivity reactions.
