For in vitro use only!

Shipping: shipped at ambient temperature

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 18.6 kDa

Accession number: P22301

Accession number: P22301

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilised (Interleukin-10 was lyophilised from a 1 mg/ml solution in PBS, pH 7.4)

Solubility: It is recommended to reconstitute the lyophilised IL-10 in bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA)

Activity: ED50: < 2 ng/ml, corresponding to a specific activity 1.5 x 107 IU/mg, determined by the dosedependent co-stimulation with murine IL-4 of MC-9 cells.

Interleukin-10 is produced by murine T-cells following their stimulation by lectins. The main source for B-cellderived Interleukin-10 in mice are Ly-1 B-cells that express CD5 and CD11. Murine keratinocytes also produce IL10. In humans IL-10 is produced by activated CD8+ peripheral blood T-cells, by T-helper CD4+ T-cell clones (resembling Th0, Th1, and Th2) after both antigen-specific and polyclonal activation, by B-cell lymphomas, and by monocytes following cell activation by bacterial lipopolysaccharides and mast cells. B-cell lines derived from patients with acquired immunodeficiency syndrome and Burkitt's lymphoma constitutively secrete large quantities of IL-10 into the conditioned medium. The synthesis of IL-10 by monocytes is inhibited by IL-4 and IL-10. Recombinant human Interleukin-10 produced in E.coli is a single non-glycosylated polypeptide chains containing 161 amino acids each.
