Cytokines

Cytokine
Introduction
Cytokines are a class of small molecule proteins or polypeptides that are stimulated, synthesized or secreted by immune cells (such as monocytes, macrophages, T cells, B cells, NK cells, etc.) and some non-immune cells (endothelial cells, epidermal cells, fibers mother cells, etc.).  Cytokines can transmit information between cells.  Cytokines have immune regulation and effector functions including the regulation of innate immunity, adaptive immunity, hematopoiesis, repair of damaged tissues, cell growth, and differentiation. Cytokines play an important role in the immune system by regulating the intensity and duration of immune responses.
Role of Cytokines in tumors
https://doi.org/10.1186/s12943-020-01294-3
Cytokines establish a conducive microenvironment for eventual tumor metastasis
Many cytokines promote or restrict each other in vivo, forming an extremely complex immune regulatory network. Specific cytokines exert their biological effects in autocrine, paracrine or endocrine modes, and have various properties such as pleiotropic, overlapping, antagonistic and synergistic. However, under certain conditions, cytokines can also participate in the occurrence of various diseases, and even trigger cytokine storm and cytokine storm syndrome, resulting in multiple organ damage, functional failure and death.
Complex and dynamic interactions between cytokines and their receptors mediate chronic inflammation and immunosuppressive tumor microenvironment (TME) leading tumor progression, metastasis, and reduced response to therapy. Autoimmune diseases are the second largest therapeutic field after tumors. Cytokines are the final effector proteins, blocking their function can effectively relieve tissue damage and inflammation in autoimmune diseases. With the improvement of biopharmaceutical technology, there is a huge growth space for targeted cytokine drugs in the future, which is a promising prospect for the treatment of tumors and autoimmune diseases.
Cytokine is a generic name that can be divided into interleukins (ILs), growth factors, tumor necrosis factors (TNFs), chemokines, colony-stimulating factors (CSFs), interferons (IFNs), etc. ACROBiosystems is providing you with a series of recombinant cytokines and their receptors with high purity, high bioactivity, and high batch-to-batch consistency to accelerate your scientific research and drug development programs.
Product Features

Closer to the natural conformation in humans due to expressed by HEK293 cells

Various species: Human, Mouse, Rat, Cynomolgus, Rhesus Macaque, Rabbit, Cannie, suitable for species cross experiments

Various labels and tags

Biotinylated cytokines are exclusively produced using the AvitagTM technology: the biotinylation only happens on the lysine residue of Avi tag; no interference with the target protein’s natural binding activities; the protein orientation is uniform when immobilized on an avidin-coated surface

High purity and homogeneity in structure are verified by both SDS-PAGE and SEC-MALS

High bioactivity of binding with receptor or antibody is verified by ELISA/SPR/BLI/cell-based assay. Protocols shared

Strict quality control to guarantee high batch-to-batch consistency (ELISA as QC test)

More comprehensive cytokine products, hot cytokine targets are available
