EBI3, IL39, IL-39EBI3, IL39p19, Interleukin-39, IL-39

Source

Human IL-39, Fc Tag (IL9-H5259) is expressed from human 293 cells (HEK293). It contains AA Arg 21 - Lys 229 & Arg 20 - Pro 189 (Accession # Q14213-1 (IL-27 beta) & Q9NPF7-1 (IL-23 alpha)).

Predicted N-terminus: Arg 21

Molecular Characterization

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 69.4 kDa. The protein migrates as 65-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 360 mM NaCl, PBS, pH7.4 with trehalose as protectant.
