Product Specifications

Abbreviation

IL9

Synonyms

HP40, IL-9, P40

Host

Baculovirus-insect Cells

Tag

C-His

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method

Purity

> 97 % as determined by SDS-PAGE

Bioactivity

Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells in the presence of 10 ng/mL of recombinant human SCF. The ED50 for this effect is typically 0.5-2 ng/mL.

Function

Met1-Ile144

Molecular Weight

The recombinant human IL9 consists of 136 amino acids and predicts a molecular mass of 15.5 kDa. rhIL9 migrates as multiple bands with the molecular mass of 19-26 kDa band in SDS-PAGE under reducing conditions due to different glycosylation.
