ELISA kits are enzyme-linked immunosorbent assays designed for the quick detection and quantitation of target proteins, antibodies, and other soluble targets of interest. RayBiotech's objective is to manufacture a diverse selection of high quality ELISA kits to serve a broad range of research interests. Our target protein selection includes a wide variety of soluble proteins (cytokines, growth factors, signaling molecules), as well as transcription factors and post-translational modifications. We strive for species diversity as well, with 17 target species including rabbit, dog and zebrafish.
Antibody screening has important public health uses in determining immunity to and prevalence of COVID-19, as well as identifying who has been infected and evaluating potential blood based therapeutics. Detect IgG, IgM, and IgA antibodies to COVID-19 N and S1 RBD proteins in serum, plasma, and dried blood samples using the COVID-19 indirect ELISA kits. Additionally, use the sandwich ELISAs for detecting N- and S-Proteins.
Sandwich ELISA kits utilize matched antibody pairs for a "sandwich-based" quantitative detection of cytokines, growth factors, receptors and other proteins. RayBiotech manufactures over 3,700 sandwich ELISA kits covering 17 different species. The 96-well plates come pre-coated with the specific capture antibodies for excellent reproducibility. Compatible sample types include plasma, serum, cell culture media, lysates, clarified body fluids
An indirect Enzyme-Linked Immunosorbent Assay (ELISA) is a common biochemical technique that is most suitable for determining total antibody concentrations in a sample. This method is commonly utilized to diagnose infection and to quantify antibodies against the invading antigen.
Phosphorylation ELISA kits are sandwich-based ELISAs specificly made for measuring phosphorylated proteins, such as MAPK, AKT, EGFR, STAT, mTOR, and other signaling molecules. This allows the researcher to screen numerous different cell lysates without performing Western Blot analyses. For normalization purposes, these kits can also measure phosphorylated protein and pan protein in one experiment. RayBiotech manufactures over 300 phospho-ELISAs for human, mouse, and rat species.
IQELISA™ is an immuno-PCR assay that combines the specificity and ease of use of an ELISA with the sensitivity of real-time PCR.
Competitive ELISA kits utilize the principle of competitive enzyme immunoassay (EIA), in which the target protein and a biotin-conjugated peptide bind competitively to a capture antibody. This method is effective for detecting peptide hormones and other molecules for which no antibody pair has been developed.
Cell-Based ELISA kits utilize the direct design principle to measure the relative amount of protein phosphorylation and monitor the effect of various treatments, inhibitors, or activators in cultured cell lines.
Transcription Factor-Enzyme Linked Immunosorbent Assays are non-radioactive assays to semi-quantitatively measure active transcription factors in nuclear extracts and cell lysates. They offer an easy, speedy, sensitive and high-throughput method to detect the activation of transcription factors.
RayBiotech offers binding assays for studying receptor-ligand or drug-target interactions. Using an ELISA-like format, the protein or small molecule of interest is coated on a 96-well microplate and potential inhibitors are then added in the presence of the interacting molecule. This assay enables rapid, high throughput, in-vitro screening of potential inhibitors. Browse ready-made kits to query Spike-receptor interactions that facilitate SARS-CoV-2 viral entry into host cells, as well as to detect drug antibodies (DA) and anti-drug antibodies (ADA).
Utilize the sandwich-based principle of detection, with a compressed work flow that allows quantitative measurement of protein concentration in only three hours.
