Rabbit anti Human Interleukin-19 antibody recognizes human IL-19 (interleukin-19), a 153 amino acid secreted helical cytokine belonging to the IL-10 family of regulatory cytokines, which is preferentially expressed in monocytes, but also expressed in B cells, and up-regulated in monocytes stimulated with lipopolysaccharide (LPS) or granulocyte-macrophage colony-stimulating factor (GM-CSF).

IL-19 has been implicated as a regulator in the inflammatory response and signals through binding to a receptor complex (IL-20R) composed of the IL-20R1 (CRF2–8) and IL-20R2 (CRF2–11 ) chains, which leads to the activation of signal transducer and activator of transcription 3 (STAT3).

Target Species
Product Form
Purified IgG conjugated to Biotin - lyophilized
Reconstitute with 0.5ml sterile PBS containing 0.1% Bovine Serum Albumin.
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended.
Antiserum Preparation
Antisera to human IL-19 were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG was prepared by affinity chromatography.
Buffer Solution
Phosphate buffered saline
Preservative Stabilisers
None present
Carrier Free
Recombinant human IL-19.
Approx. Protein Concentrations
IgG concentration 0.1mg/ml after reconstitution.
For research purposes only
