Human IL-17F Protein, His Tag, low endotoxin (MALS verified)
Synonym
IL-17F, Interleukin-17F, Cytokine ML-1
Source
Human IL-17F, His Tag (ILF-H5244) is expressed from human 293 cells (HEK293). It contains AA Arg 31 - Gln 163 (Accession # Q96PD4-1).
Predicted N-terminus: His
Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 16.8 kDa. The protein migrates as 22-25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
The protein is designed as a dimer.
Endotoxin
Less than 0.01 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
Interleukin-17F (IL17F) is also known as Interleukin-24 (IL24), Cytokine ML-1, is a secreted disulfide-linked homodimer which belongs to the IL-17 family. There are at least six members of the IL-17 family in humans and in mice: IL-17A, IL-17B, IL-17C, IL-17D, IL-17E (also called IL-25) and IL-17F (also called IL-24). IL-17 represents a family of structurally related cytokines that share a highly conserved C-terminal region but differ from one another in their N-terminal regions and in their distinct biological roles. IL-17F / IL-24 is expressed in activated, but not resting, CD4+ T-cells and activated monocytes. IL17F / Interleukin-24 stimulates the production of other cytokines such as IL-6, IL-8 and granulocyte colony-stimulating factor, and can regulate cartilage matrix turnover. IL17F / IL-24 stimulates PBMC and T-cell proliferation and Inhibits angiogenesis. Defects in IL17F are the cause of familial candidiasis type 6 (CANDF6).
