Product details:
Human SEPP1 SimpleStep ELISA® kit (ab303751) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Human SEPP1 protein in serum, plasma (hep), plasma (cit), plasma (EDTA) and cell culture supernatant. Quantitate Human SEPP1 with 12.65 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.

SEPP1 also known as Selenoprotein P is a glycoprotein characterized by multiple selenocysteine residues which play a critical role in its function. SEPP1 has a molecular mass of approximately 60 kDa. It expresses predominantly in the liver but can be found in other tissues like the brain kidney and plasma. In the liver it is involved in selenium transport and homeostasis carrying selenium to other tissues through the blood.
Biological function summary
SEPP1 acts as an antioxidant helping to defend cells against damage from reactive oxygen species. It exists as part of a complex system within the body to balance oxidative stress. Moreover SEPP1 contributes to the recycling of selenium in the body ensuring adequate supply for selenoprotein synthesis in various tissues. It serves essential functions in neurological health and immune response leveraging its selenium content to protect cells and maintain cellular activities.
Pathways
SEPP1 is significantly involved in selenium homeostasis and the oxidative stress response pathways. It interacts with proteins like glutathione peroxidase (GPx) and thioredoxin reductase which also depend on selenium for their antioxidant activities. The involvement of SEPP1 in these pathways is critical for mitigating oxidative damage and supporting the function of other selenium-dependent enzymes essential for maintaining cellular health.
SEPP1 is associated with neurodegenerative diseases and certain types of cancer. Dysregulation of SEPP1 and selenium homeostasis may contribute to the development and progression of conditions such as Alzheimer's disease potentially involving interactions with amyloid precursor protein (APP) and tau proteins. In cancer alterations in SEPP1 expression have been linked to colorectal cancer through pathways intersecting with proteins influencing cell proliferation and apoptosis such as Bcl-2 and p53 indicating its potential role in tumor biology.
