Introduction

Interleukin-9 is a protein that acts as one of the regulators of hematopoiesis. IL-9 is an enhancer of cells and megakaryoblastic leukemic cells’ growth. Among this protein’s producers we can find cells like mast cells, Treg, NKT cells, Th17, Th2, ILC2, and Th9 cells in various amounts. Th9 are the primary CD4 cells (T cells) that IL-9 is produced in.

Description

IL-9 Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 132 amino acids (19-144 aa) and having a molecular mass of 14.9kDa.
IL-9 is fused to a 6 amino acid His tag at C-terminus and purified by proprietary chromatographic techniques.

Source

Sf9, Baculovirus cells.
