Product details:
Human ROBO4 ELISA kit (ab282879) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Human ROBO4 protein in human serum, plasma, and supernatants. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human ROBO4 with 4.56 pg/mL sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Human ROBO4 (Roundabout homolog 4) is a receptor SLIT2 among Slit family of proteins. Human ROBO4 is involved in the maintenance of endothelial barrier organization and function. Studies suggest ROBO4 is involved in angiogenesis and vascular patterning. ROBO4 may mediate the inhibition of primary endothelial cell migration by Slit proteins.

Roundabout homolog 4 (Robo4) is a protein weighing approximately 107 kDa. It belongs to the immunoglobulin superfamily and is sometimes referred to as Magic Roundabout. Robo4 primarily gets expressed in endothelial cells playing an important function in vascular biology. It is characterized by having two immunoglobulin-like domains and two fibronectin type III domains making it distinct among the other Robo family members.
Biological function summary
Robo4 stabilizes the vascular network interacting actively with the guidance molecule Slit proteins. It is not part of a larger protein complex but engages directly with these ligands to influence endothelial cell migration and vascular permeability. Its role is significant in maintaining the structural integrity of blood vessels ensuring the appropriate cellular responses important for proper vascular function.
Pathways
Robo4 engages in the Slit-Robo signaling pathway that is essential for vascular development and remodeling. This pathway helps inhibit excessive endothelial migration and angiogenesis. Robo4 interacts with proteins like Slit2 which binds to it as a ligand to mediate these effects. Through this pathway Robo4 performs an important function in processes such as vascular homeostasis and angiogenesis regulation.
Robo4 appears to have connections to vascular-related conditions including diabetic retinopathy and age-related macular degeneration. The protein influences pathological angiogenesis which is a hallmark in the progression of these diseases. In these contexts Robo4's interaction with Slit2 proves important as it can restrain abnormal vascular growth offering potential therapeutic angles for treatment approaches focused on targeting the Slit-Robo pathway.
