表达区间及表达系统（Source）
Human IL-23A&Rat IL-12B Heterodimer Protein, His Tag&Tag Free (ILB-HR52W3) is expressed from human 293 cells (HEK293). It contains AA Arg 20 - Pro 189 (IL23A) & Met 23 - Ser 335 (IL12B) (Accession # Q9NPF7-1 (IL23A) & Q9R278-1 (IL12B)).
Predicted N-terminus: Arg 20 (IL23A) & Met 23 (IL12B)
Request for sequence蛋白结构（Molecular Characterization）
Human IL-23A & Rat IL-12B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of IL-23A and IL-12B, has a calculated MW of 20.6 kDa (IL-23A) and 35.9 kDa (IL-12B). Subunit IL-23A is fused with a polyhistidine tag at the N-terminus and subunit IL-12B contains no tag. The reducing (R) protein migrates as 23 kDa (IL-23A) and 45 kDa and 47 kDa (IL-12B) respectively due to glycosylation.
