表达区间及表达系统（Source）
Cynomolgus IL-23A&Mouse IL-12B Heterodimer Protein, His Tag&Tag Free (ILB-CM52W8) is expressed from human 293 cells (HEK293). It contains AA Val 22 - Pro 189 (IL23A) & Met 23 - Ser 335 (IL12B) (Accession # A0A2K5TLV4-1 (IL23A) & P43432-1 (IL12B)).
Predicted N-terminus: His (IL23A) & Met 23 (IL12B)
Request for sequence蛋白结构（Molecular Characterization）
This protein carries polyhistidine tag at the N-terminus. The protein has a calculated MW of 20.3 kDa (IL23A) & 35.8 kDa (IL12B). The protein migrates as 20-23 kDa (IL23A) & 40-42 kDa and 43-46 kDa (IL12B) 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.
