Source

Human IL-7 RA&TSLP R Heterodimer Protein, Fc Tag&Fc Tag (ILR-H5255) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Asp 239 (IL-7 RA) & Gln 23 - Lys 231 (TSLP R) (Accession # P16871-1 (I66T, V138I) (IL-7RA) & Q9HC73-1 (TSLPR)).

Predicted N-terminus: Glu 21 (IL-7 RA) & Gln 23 (TSLP R)

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

Human IL-7 RA&TSLP R Heterodimer Protein, Fc Tag&Fc Tag is produced by co-expression of IL-7 RA and TSLP R, has a calculated MW of 51.7 kDa (IL-7 RA) and 50.3 kDa (TSLP R). Subunit IL-7 RA is fused with a human IgG1 Fc fragment at the C-terminus and subunit TSLP R is fused with a human IgG1 Fc fragment at the C-terminus. The reducing (R) protein migrates as 60-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker due to glycosylation.

Endotoxin

Less than 0.01 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 PBS, pH7.4 with trehalose as protectant.
