Általános leírás
Interleukin-6, human (hIL-6), is produced in E. coli and purified by standard chromatographic techniques.
Egyediség
Recombinant IL-6, human is effective on mouse and human cells.
IL-6, a 26 kD protein, also known as B-cell stimulatory factor 2 (BSF-2, BCDF), interferon-β2 (IFN-β2), hybridoma/plasmacytoma growth factor (H(P)GF), and hepatocyte-stimulating factor is produced by many cell types (e.g., T-cells, monocytes, fibroblasts, endothelial cells). IL-6 induces the terminal maturation of activated B-cells into antibody-producing cells (B-cell differentiation activity. The hepatic acute phase response is induced by IL-6 (hepatocyte-stimulating activity). It was shown that IL-6 and IL-3 act synergistically to support the proliferation of hematopoietic stem cells (hemapoietic activity), however, IL-6 does not have antiviral activity, although it has been called IFN-β2. High affinity receptors for IL-6 are found on many cell types.

Alkalmazás
Recombinant IL-6, human, is a growth factor for murine and human B-cells. It can be used to replace feeder cells in the preparation of murine and human hybridomas.
Biokémiai/fiziológiai hatások
Interleukin-6 participates in several pleiotropic functions in various types of cells through its specific receptor (IL-6-R). It has been suggested that interleukin-6 may participate in the interaction between neuroendocrine and immune system by activating adrenocorticotropic hormone secretion. It has also been reported that IL-6 stimulates the bonding of receptor (IL-6-R) with a non-ligand-binding membrane glycoprotein, gp130.
Minőség
Purity: 95% pure as determined by HPLC or SDS-PAGE [Endotoxin level: <0.1 EU/μg (LAL-test), <10 EU/ml (LAL-test).
Note: 1 EU corresponds to 0.1 ng
Note: 1 EU corresponds to 0.1 ng
Szekvencia
Chain Length 184 AA
The primary structure of recombinant human IL-6 is identical to that of natural human IL-6 (one polypeptide chain, 184 amino acids), however, it contains an altered sequence within the first 15 amino-terminal amino acids.
Egység definíció
EC50 definition: The amount of hIL-6 that is required to support half-maximal stimulation of cell proliferation (MTT cleavage) with 7TD1 cells (1 unit equals <0.01 ng).
Fizikai forma
Solution, filtered through 0.2 μm pore size membrane.

The addition of macrophage feeder cells or conditioned medium has been shown to increase the yield of murine hybridomas obtained after the fusion of myeloma cells and activated B lymphocytes. It has been shown recently that the conditioned medium contains

The need to activate B lymphocytes on antigen challenge is tempered by the requirement that the response is terminated when the challenge has been negotiated. Regulation is probably mediated via the interaction of soluble factors with surface receptors. Here, John

In order to assess the effect of interleukin-6 on the hypothalamo-pituitary-adrenal axis, we administered recombinant human interleukin-6 to conscious, freely-moving rats. The intravenous injection of interleukin-6 significantly increased the plasma level of adrenocorticotropic hormone 30 min after the injection in

Hybrid hybridomas are obtained by fusion of two cells, each producing its own antibody. Several authors have reported the construction of murine hybrid hybridomas with the aim to obtain bispecific monoclonal antibodies. We have investigated, in a model system, the
