Source

Human IL-23A&Rat IL-12B Heterodimer Protein, His Tag&Tag Free (ILB-HR52W4) is expressed from human 293 cells (HEK293). It contains AA Arg 20 - Pro 189 & Met 23 - Ser 335 (Accession # Q9NPF7-1 & Q9R278-1).

Predicted N-terminus: His & Met 23

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Human IL-23A&Rat IL-12B Heterodimer Protein, His Tag&Tag Free, produced by co-expression of IL23A and IL12B, has a calculated MW of 20.6 kDa (IL23A) and 35.9 kDa (IL12B). Subunit IL-23A is fused with a polyhistidine tag at the N-terminus and subunit IL-12B contains no tag. The protein migrates as 23-25 kDa,43 kDa and 45 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 0.0005 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
