Antigens Biomarkers Products & Reviews

Frequently referred to as "synthetic antibodies", aptamers are single stranded DNA molecules which can specifically recognize and bind to the targeted protein.

Recombinant SARS-CoV-2, S1 Subunit Protein (RBD) with C-terminal His tag, derived from the transfected human HEK293 cells.

Recombinant SARS-CoV-2 Spike Protein, S1 Subunit derived from E.coli

Recombinant SARS-CoV-2 Spike Protein, S2 Subunit derived from E.coli

Recombinant SARS-CoV-2 Nucleocapsid Protein derived from E.coli

Use the Bio-Plex Pro Human Serology Reagent when performing Bio-Plex Pro singleplex or combined (multiplexed) assays with Bio-Plex SARS-CoV-2 N, RBD, S1, and/or S2, and/or nucleocapsid coupled magnetic beads and Human IgA, IgG, or IgM detection in human and non-human primate samples.

Provides sensitive and specific quantitation of antibodies against four SARS-CoV-2 proteins: nucleocapsid, receptor binding domain, spike 1, and spike 2 viral proteins.

pTau181 Biomarker Assay

Single molecule array (Simoa) testing is a protein detection technique that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques. Traditional ELISA measurements are limited to pg/ml levels of detection. The RayBio Ultrasensitive Simoa Testing Services can achieve sensitivity as low as femtogram (fg/ml) levels, allowing the quantification of biomarkers at concentrations previously difficult…

The RayBiotech Monkeypox Virus 1-Step High Throughput PCR Kit is a ready to use PCR assay for the detection of monkeypox virus (MPXV) DNA. The 1-Step Nucleic Acid Stabilization Buffer eliminates the need for DNA extraction and purification steps.

Glial Fibrillary Acidic Protein (GFAP) is a class-III intermediate filament majorly expressed in astrocytic glial cells in the central nervous system. Astrocytes play a variety of key roles in supporting, guiding, nurturing, and signaling neuronal architecture and activity. Monomeric GFAP is about 55kD. It is capable of forming both homodimers and heterodimers; GFAP can polymerize with other type III proteins or with neurofila…

The Simoa Human Neurology 4-Plex E (N4PE) assay simultaneously measures four biomarkers in EDTA plasma and CSF. The targets are Abeta 40 (Aβ40), Abeta 42 (Aβ42), Glial Fibrillary Acidic Protein (GFAP™), and Neurofilament light (Nf-L). Each biomarker has been demonstrated to have significance for the investigation of neurodegeneration and brain injury, and to have utility for monitoring effectiveness of drug discovery and devel…

The Simoa Human Neurology 2-Plex assay (N2PB) measures two important neurology biomarkers in both cerebrospinal fluid (CSF) and blood. The two targets are neurofilament light (Nf-L) and glial fibrillary acidic protein (GFAP™), which have been studied as indicators of traumatic brain injury (TBI) severity. N2PB has been developed as a 2-Plex version of the Neurology 4-Plex B assay (N4PB). *Banyan GFAP™ is a registered tradem…

The combination of the six serum biomarkers that discriminate between disease-free and ovarian cancer patien…

Innova Biosciences – Antibody Conjugation Service Bio-conjugates can be challenging to optimise and time consuming to produce: 1. Too much conjugation may result in the target protein becoming inactive and insoluble. 2. Too little conjugation can result in weak signals. 3. Our competitors require milligrams of your precious material and have a 2 week process time. Fast & FAb™ Antibody Conjugation Service – Innova Biosciences t…
