Mouse IL-11 Recombinant Protein: Image 1
Serial dilutions of Mouse IL-11 Recombinant Protein were added to B9 cells. Cell proliferation was measured and the linear portion of the curve was used to calculate the ED50.

The purity of Mouse IL-11 Recombinant Protein was determined by SDS-PAGE of 1 µg reduced (+) and non-reduced (-) recombinant mIL-11 and staining with Coomassie Blue.

Storage

Mouse IL-11 Recombinant Protein is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/ml which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage.

Product Description

MW (kDa) 19.3
Purity A greater than or equal to 95% purity was determined by SDS-PAGE.
Endotoxin Endotoxin levels are less than or equal to 1 EU / 1 μg mIL-11.
Activity The bioactivity of recombinant mIL-11 was determined in a B9 cell proliferation assay. The ED50 of each lot is less than or equal to 250 ng/ml.

Source / Purification

Recombinant mouse IL-11 was expressed in E. coli and is supplied in a lyophilized form.

Background

Interleukin-11 (IL-11) was initially cloned as a mediator of plasmacytoma cell proliferation and was later found to exhibit a wide variety of biological effects in neural cells as well as in the hematopoietic and immune systems (1). IL-11 belongs to the interleukin-6 (IL-6)-type subfamily of long-chain helical cytokines, including IL-6, ciliary neurotrophic factor (CNTF), leukemia inhibitory factor (LIF), oncostatin M, and cardiotrophin-1, which all share the glycoprotein gp130 as a signal transducing receptor component. IL-11 acts on cells expressing gp130 and the IL-11 receptor (IL-11R) α subunit. Both receptor subunits belong to the family of class I cytokine receptors. The complex of IL-11 and IL-11R triggers the activation of gp130 most likely by enforcing gp130 homodimerization (2). As a consequence of gp130 activation, several cytoplasmic signal transduction cascades are initiated from the Janus kinase (Jak)/signal transducer and activator of transcription (Stat) pathway, which has attracted considerable attention. Initiation of the Jak/Stat pathway in response to IL-11 requires Jak1 and leads predominantly to the activation of Stat3 (3,4).
