Rat IL-7R alpha/CD127 Antibody Summary

Species Reactivity

Rat

Specificity

Detects rat IL-7 R alpha /CD127 in direct ELISAs and Western blots. In direct ELISAs, approximately 60% cross-reactivity with recombinant mouse IL-7 R alpha and less than 10% cross-reactivity with recombinant human IL-7 R alpha is observed.

Detection of Rat IL‑7 R alpha /CD127 by Western Blot. Western blot shows lysates of rat spleen tissue. PVDF Membrane was probed with 1 µg/mL of Rat IL-7 Ra/CD127 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5607) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for IL-7 Ra/CD127 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: IL-7R alpha/CD127

IL-7 R alpha (IL-7 receptor alpha; also CD127) is a 60-70 kDa member of the type I cytokine receptor family of molecules. It is expressed on resting naïve and memory CD8+ T cells, DN thymocytes, pre-B cells, Th1 CD4+ T cells, dendritic cells and monocytes. IL-7 R alpha heterodimerizes with both the gamma c chain to create the IL-7 receptor, and the TSLPR subunit to generate the TSLP receptor. IL-7 R alpha participates in T cell differentiation, naïve T cell survival, and CD4+ thymocyte proliferation. Mature rat IL-7 R alpha is a 437 aa type I transmembrane glycoprotein. It contains a 219 aa extracellular region (aa 21-239) that possesses one type III fibronectin domain (aa 129‑222), and a 193 aa cytoplasmic tail that shows a key phosphorylation site at Tyr447. Over aa 21‑239, rat IL-7 R alpha shares 79% and 67% aa identity with mouse and human IL-7 R alpha, respectively.
