Purified Recombinant Human IL-11 (Accession # P20809)
<0.1 EU/µg as determined by the LAL method
This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.3 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.
Storage and Handling
The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 2 - 8 µg/ml. A suitable detection antibody is PN:I-266 at a concentration of approximately 0.1-0.4 µg/ml. A suggested standard for this assay is PN:I-194.
Western Blotting: To detect Human IL-11 this monoclonal antibody can be used at a concentration of 1 - 2 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:M114 and a chromogenic substrate such as PN:T343. The detection limit for Human IL-11 is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-194.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Mouse Anti-Human Interleukin-11 (IL-11) (Clone 22616) recognizes an epitope on Human IL-11. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype. This antibody shows 100% cross-reactivity with rmIL-11 and no cross-reactivity with rhIL-6, rhIL-6 R, rhLIF, rhOSM, rhCT-1, rhCNTF, or rhCLC.
Interleukin 11 (IL-11) is a multifunctional cytokine isolated from bone marrow-derived stromal cells. It is a key regulator of multiple events in hemtaopoiesis, most notably the stimulation of megakaryocyte maturation.1 It is also known under the names Adipogenesis inhibitory factor (AGIF)2 and Oprelvekin. IL-11 improves platelet recovery after chemotherapy-induced thrombocytopenia, induces acute phase proteins, modulates antigen-antibody responses, participate in the regulation of bone cell proliferation and differentiation and could be use as a therapeutic for osteoporosis. Besides from lymphopoietic/hematopoietic and osteotrophic properties, it has functions in many tissues such as brain, gut and testis.
