Format: Liquid

Reconstitution: For maximum results, quick spin vial prior to opening. Stock solutions should be prepared at no less than 10 μg/mL in sterile buffer (PBS, HPBS, DPBS, and EBSS) containing carrier protein such as 1 % BSA, or FBS. After dilution, the cytokine can be stored between 2 °C and 8 °C for one month or from -20 °C to -70 °C for up to 3 months.

Buffer: 0.22 μm filtered protein solution is in PBS.

Conseil sur la manipulation: Avoid repeated freeze/thaw cycles.

Stock: -20 °C

Stockage commentaire: Unopened vial can be stored between 2°C and 8°C for three months, at -20°C for six months, or at -70°C for one year.

Détail du antigène

Antigène: IL-11 (IL11) (Interleukin 11 (IL11))

Autre désignation: IL-11

Sujet: IL-11, a member of the IL-6 family of cytokines, exerts a wide range of biological effects on various cell types including hematopoietic cells, hepatocytes, adipocytes, neurons, and osteoblasts. IL-11 works synergistically with other growth factors including SCF, IL-4, IL-3, IL-7, IL-12, IL-13, and GM-CSF to stimulate the proliferation of cells from several hematopoietic lineages. Binding of IL-11 to IL-11 receptor (IL-11R) induces membrane bound gp130 homodimerization and triggers STAT3 phosphorylation by JAK. IL-11 shares the common receptor subunit gp130 with IL-6, IL-27, LIF, OSM, CNTF, CT-1, CLC, and NP. Female mice deficient in IL-11R revealed an important role for IL-11 in embryonic implantation. In addition, IL-11 shows anti-inflammatory activity in models of inflammatory bowel disease, chemotherapy induced oral mucositis, and inflammatory arthritis. IL-11 and IL-13 are highly expressed in asthmatic airways (Th2 response), and IL-11 can inhibit Th1 responses and inhibits the production of Th1 cytokines such as IL-12 and shifts inflammation in Th2 direction. Elevated IL-11 expression is associated with tumor grade and invasion in gastric cancer. Recombinant human IL-11 has been clinically approved to improve platelet recovery after chemotherapy-induced thrombocytopenia.

Poids moléculaire: The 180 amino acid recombinant protein has a predicted molecular mass of approximately 19.3 kDa. The DTT-reduced and non reduced proteins migrate at approximately 19.3 kDa by SDS-PAGE. The N-terminal amino acid is Valine.
