Scientific Background
Human IL5RA/IL-5 Rα Protein — also known as CDw; HSIL5R; IL5RA; CD125; CDw125; HSIL5R3; IL5R; IL-5 receptor subunit alpha; IL-5R subunit alpha; IL-5RA; IL-5R-alpha; — Interleukin-5 Receptor alpha (IL-5Rα; CD125) is a 60 kDa hematopoietin receptor that plays a dominant role in eosinophil biology. Mature human IL-5 Rα consists of a 322 aa extracellular domain (ECD) with a WSxWS motif and a four cysteine motif; a 20 aa transmembrane segment; and a 58 aa cytoplasmic domain. Within the ECD; human IL-5Rα shares 71% aa sequence identity with mouse and rat IL-5 Rα. Alternate splicing of human IL-5 Rα generates soluble secreted forms which function as IL-5 antagonists. The high affinity receptor for IL-5 is a complex that consists of the ligand binding IL-5 Rα and t
Research into Human IL5RA/IL-5 Rα Protein supports investigations in immune regulation and inflammatory responses, with implications for cytokine biology.
Product Description
HEK293 Mammalian CellsC-His
Produced in HEK293 Mammalian Cells, preserving native glycosylation patterns and supporting biological activity in cell-based assays.
The C-His enables single-step affinity purification and can also serve as a handle for direct detection using anti-tag antibodies without target-specific reagents.
Expression region: Asp21-Glu335.

This protein is produced in HEK293 mammalian cells. Mammalian expression preserves glycosylation and folding closest to the native protein, supporting biological activity in cell assays.
Purity: > 95% as determined by reducing SDS-PAGE., confirmed by reducing SDS-PAGE. Endotoxin level: < 1.0 EU per μg of the protein as determined by the LAL method., measured by LAL assay — critical for cell-based studies. Identity is verified by peptide mapping or N-terminal sequencing on request.
Yes — biological activity is confirmed per lot. Activity data: Not validated for activity. Run a titration in your own system to establish optimal working concentration before committing all samples.
Reconstitution: Please refer to the printed manual for detailed information.. Storage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-. Avoid repeated freeze-thaw — each cycle risks partial denaturation.
This protein is validated for ELISA, Functional Assay (In Vitro). It is commonly used as an ELISA standard, binding partner in SPR/BLI, or stimulant in cell-based functional assays. Validate performance in your specific format before use in critical experiments.
