title: Molecular cloning, expression and characterization of the Canis familiaris interleukin-4.
abstract: Interleukin 4 (IL-4) is an important regulatory cytokine produced by activated T lymphocytes and mast cells, and regulates the growth and differentiation of cells such as B and T lymphocytes. The rapid amplification of cDNA ends (RACE) was used to clone the canine IL-4 gene. It was expressed in mammalian cells and Escherichia coli. Monoclonal antibodies were raised to rcIL-4 for use in an enzyme-linked immunosorbent assay (ELISA). This will facilitate studies on the role of cIL-4 in inflammatory diseases, particularly rheumatoid arthritis.
