Product Overview
This rabbit polyclonal antibody targets interleukin-7 (gene IL7) in human samples and is validated for ELISA and Western blot. The predicted molecular weight is 20.2 kDa, and the supplier reports an observed band at about 75 kDa.
Interleukin-7 (IL-7) is a cytokine produced by stromal and epithelial cells that is essential for lymphocyte development and homeostasis. Through IL-7Rα and the common gamma chain, it activates JAK1/JAK3, STAT5 and PI3K–AKT signaling to support the development of T and B cells and the survival of naive and memory T cells.

|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): K562 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant human IL7 fragment (Asp26–His177), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 56.4% and 57%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes interleukin-7 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
