Source / Purification

Recombinant mouse IL-10 (mIL-10) Ser19 - Ser178 (Accession # NP_034678) was produced in E. coli at Cell Signaling Technology.

Product Description

Purity:

>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mIL-10. All lots are greater than 98% pure.


Molecular Formula:

Recombinant mIL-10 does not have a Met on the amino terminus and has a calculated MW of 18,976. DTT-reduced and non-reduced protein migrate as 19 kDa polypeptides. The expected amino-terminal SRGQY of recombinant mIL-10 was verified by amino acid sequencing.


Bioactivity:

The bioactivity of recombinant mIL-10 was determined in a MC/9 cell proliferation assay. The ED50 of each lot is between 0.3-1.3 ng/ml.


Endotoxin:

Less than 0.01 ng endotoxin/1 μg mIL-10.


Product Usage Information

Formulation:

With carrier: A 0.22 μm filtered solution of 0.33 mg/ml mIL-10 in PBS, pH 7.2 containing 20 μg BSA per 1 μg mIL-10. Carrier free: A 0.22 μm filtered solution of 0.33 mg/ml mIL-10 in PBS, pH 7.2.


Storage: Stable at 4°C for 1 year after receipt. Maintain sterility. Do not store frozen.

IL-10 is an anti-inflammatory cytokine that is produced by T cells, NK cells, and macrophages (1,2). IL-10 initiates signal transduction by binding to a cell surface receptor complex consisting of IL-10 RI and IL-10 RII (1). Binding of IL-10 leads to the activation of Jak1 and Tyk2, which phosphorylates Stat3 (1,3). The anti-inflammatory activity of IL-10 is due to its ability to block signaling through other cytokine receptors, notably IFNγ receptor, by upregulating expression of SOCS1 (1,3). In addition, IL-10 promotes T cell tolerance by inhibiting tyrosine phosphorylation of CD28 (4,5). IL-10 is an important negative regulator of the immune response, which allows for maintenance of pregnancy (1). In contrast, increased IL-10 levels contribute to persistent Leishmania major infections (6).
