FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: Western blotting3,4, immunofluorescence3,4, and immunohistochemistry of frozen sections5 and formalin-fixed paraffin-embedded sections3. ITEM-4 antibody has no effect on TWEAK-induced MAPK activation in RAW cells1.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

CD266 is a 14 kD transmembrane protein known as TWEAK receptor (TWEAK-R) or fibroblast growth factor inducible 14 (Fn14). It is member 12A of the tumor necrosis factor receptor superfamily (TNFRSF12A) expressed at low levels in a variety of tissues, such as heart, placenta, lung, muscle, and pancreas. TWEAK-R binds TWEAK (CD255) and interacts with the cytoplasmic proteins TRAF1, 2, and 3. The engagement of Fn14 can induce cell death and may play a role in inflammation, hepatocyte growth, and liver neoplasia.

Other Names: Fibroblast growth factor-inducible 14 kD protein (Fn14), TWEAK receptor, TWEAK-R, TNFRS12A
Structure: Transmembrane TNF superfamily receptor, contains no death domain, 14 kD
Distribution: Widely expressed in heart, placenta, lung, muscle, kidney, pancreas, and HUVEC
Function: Binds to TWEAK (CD255), thought to play a role in cell death and inflammation
Ligand Receptor: TWEAK (CD255); interacts with cytoplasmic proteins TRAF1, 2, and 3
