表达区间及表达系统(Source)
Cynomolgus IL-2, His Tag (IL2-C5249) is expressed from human 293 cells (HEK293). It contains AA Ala 21 - Thr 154 (Accession # Q29615-1).
Predicted N-terminus: His
Request for sequence蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 17.4 kDa. The protein migrates as 18 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
