Source

Mouse IL-4 R alpha & IL-13 R alpha 1 Protein, His Tag&His Tag (ILR-M52H8) is expressed from human 293 cells (HEK293). It contains AA Ile 26 - Arg 233 & Ala 26 - Thr 340 (Accession # NP_001008700 & NP_598751.3).

Predicted N-terminus: Ile 26 & Ala 26

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Mouse IL-4 R alpha & IL-13 R alpha 1 Protein, His Tag&His Tag, produced by co-expression of IL-4 R alpha and IL-13 R alpha 1, has a calculated MW of 29.6 kDa (IL-4 R alpha) and 41.2 kDa (IL-13 R alpha 1). Subunit IL-4 R alpha is fused with a polyhistidine tag at the C-terminus, and subunit IL-13 R alpha 1 contains a polyhistidine tag at the C-terminus. The protein migrates as 38-43 kDa and 55-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.

Purity

>90% as determined by SDS-PAGE.
