Applications : Western Blot

Sample type: mice

Review: The expression of each protein in the skin from mice was examined by a Western blot analysis. The histogram shows quantitative representations of each protein. We showed that the administration of IL-4Rα neutralization antibodies to the bleomycin-treated mice attenuated the STAT6 activation in the skin.

Target Background

Carries out a dual signal transduction and activation of transcription. Involved in IL4/interleukin-4- and IL3/interleukin-3-mediated signaling.
