Interleukin-4 plays a central role in orchestrating immune responses, functioning as a pleiotropic cytokine that drives B-cell activation, T-helper cell differentiation, and immunoglobulin class switching. Beyond its fundamental immunological functions, IL-4 signaling has garnered significant attention in cancer research, where it influences tumor microenvironment dynamics and can modulate anti-tumor immune responses. Understanding IL-4 expression patterns in both normal and pathological tissues provides valuable insights into disease mechanisms and potential therapeutic targets.
This recombinant monoclonal antibody, clone 5D8, offers researchers the reproducibility advantages inherent to recombinant technology. Because the antibody sequence is defined and produced through controlled expression systems, you can expect consistent performance across experiments and between lot numbers, eliminating the variability that can complicate long-term studies or multi-site collaborations. The rabbit IgG format, purified by affinity chromatography, ensures high specificity for human IL-4 detection.
Validation in immunohistochemistry demonstrates reliable performance in formalin-fixed, paraffin-embedded tissues. Testing in human breast cancer tissue sections using a Leica Bond system with citrate buffer antigen retrieval at pH 6.0 showed effective staining at 1:100 dilution, with recommended working dilutions ranging from 1:50 to 1:200 depending on your specific tissue and detection system. The antibody has also been validated for ELISA applications, providing flexibility across different experimental workflows.
For researchers investigating IL-4 biology in cancer immunology, inflammatory conditions, or basic immune cell function, this antibody provides a dependable tool for characterizing cytokine expression in human tissue samples and experimental systems.
