表达区间及表达系统（Source）

Rat IL-4 R alpha & IL-13 R alpha 1 Protein, His Tag&His Tag (ILR-R52H5) is expressed from human 293 cells (HEK293). It contains AA Ile 26 - Arg 232 & Thr 27 - Thr 342 (Accession # Q63257-1 & Q561K3).

Predicted N-terminus: Ile 26 & Thr 27

蛋白结构（Molecular Characterization）

Rat 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 29.1 kDa (IL-4 R alpha) and 41 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 43-53 kDa and 60-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

纯度（Purity）
