Mouse monoclonal antibodies (Mac 002 and Mac 003) raised against recombinant human Interleukin-2 (rec IL-2), were developed for use as assay and purification reagents. In the Immunoradiometric assay, (IRMA), 125I-Mac 002 is used as tracer, with sheep polyclonal anti-rec IL-2 on the solid phase. This reliably measures rec IL-2 in the range 3-1000 ng/ml. The assay measures natural IL-2 with a lower sensitivity. For some samples of IL-2, the amount detected by IRMA is greater than expected from the biological assays, presumably because there are IL-2 molecules with antigenic, but not biological activity. This is a possible source of variation in the specific activities observed in different preparations of of IL-2. In the purification reagent, Mac 003 is immobilised on sepharose CL-4B to purify recombinant IL-2 from less than 1% in an E. Coli extract, to greater than 90% purity, in a single step with greater than 80% yield.

The pattern of expression of cytokine mRNA in the lesions of anal furunculosis was evaluated in tissue biopsies from 15 dogs, and compared with the pattern in control skin samples from 24 dogs, by reverse-transcriptase PCR using canine cytokine-specific primers and a semi-quantitative multiplex PCR assay. Interleukin-2 (IL-2) was detected in 11 of the 15 affected dogs but in only one of the controls, and interferon-gamma was detected in 14 of the affected dogs but none of the controls. In contrast, IL-4 was detected only in one of the affected dogs. Increased expression of mRNA for IL-1beta, IL-6, tumour necrosis factor alpha, IL-8, IL-10 and transforming growth factor beta1 was detected in the biopsies from the lesions of anal furunculosis relative to the control tissues (P < 0.05).
