Specifications

Product Data
Species	Mouse
Expression Host	E. coli
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) MLRRCLISVDMRLIEKSFHEIKRAMQTKDTFKNVTILSLENLRSIKPGDVCCMTNNLLTFYRDRVFQDHQERSLEVLRRISSIANSFLCVQKSLERCQVHRQCNCSQEATNATRIIHDNYNQLEVSSAALKSLGELNILLAWIDRNHLETPAA with polyhistidine tag at the C-terminus.
Tag	His Tag (C-term)
Predicted MW	The protein has a calculated MW of 18.54 kDa. The protein migrates as 17-25 kDa under reducing condition (SDS-PAGE analysis).
Purity	>98% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4.
Applications	Cell culture
Storage	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Bioactivity	Measure by its ability to induce proliferation in BaF3 cells transfected with human IL-20 R alpha and human IL-20 R beta. The ED₅₀ for this effect is <0.6 ng/mL.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.
Reference Data
UniProt ID	Q8CJ70
Synonyms	Il19
Summary	Interleukin 19 (IL-19) predicts a molecular mass of 35.8 kDa, is a type of anti-inflammatory cytokine. It promotes the Th2 T-cell response which supports an anti-inflammatory lymphocyte phenotype, dampens the Th1 T-cell response and IFNγ secretion, increases IL-10 expression in peripheral blood mononuclear cells, and inhibits the production of IgG from B cells.
