Save 25% on All RayBiotech ELISA Kits
Enzyme-Linked Immunosorbent Assay (ELISA) is a widely used analytical technique that allows for the detection and quantification of specific proteins, antibodies, and antigens in a sample. ELISA operates on the principle of antigen-antibody interaction, where the presence of a target molecule is indicated by a color change after the addition of an enzyme-linked secondary antibody.

Some Featured Products
Competitive ELISA
Competitive ELISA is an enzyme immunoassay (EIA), in which the target protein and a biotin-conjugated peptide bind competitively to a capture antibody. This competition/inhibition assay principle requires only a single antibody, generating signal output by interaction of the biotinylated competitor with streptavidin-HRP. Thus, the competitive ELISA kits, also known as EIA kits, are particularly useful for detecting peptide hormones and other molecules for which no antibody pair exists, or for which antibody pairs cannot be developed.
Sandwich ELISA
Get reliable and reproducible quantitative detection based on well-validated antibody pairs. RayBiotech offers sandwich ELISA kits for the quantification of soluble proteins, with over 4000 target analytes across 16 species. These kits are designed for sensitive, specific, and quantitative analyte detection.
Indirect ELISA
An indirect ELISA is a common biochemical technique that detects an antibody using a labeled secondary antibody. This assay is primarily used to detect the total antibody amount in a sample. This method is commonly utilized to diagnose infection and to quantify antibodies against an invading antigen.
Phosphorylation ELISA
Phosphorylation ELISA kits are a rapid, sensitive, high-throughput, cost-effective and convenient methods for monitoring the activation of important biological pathways in cells or tissues. Unlike immunoblots, which require several days of processing to obtain parallel signals for phosphorylated and total target protein, the Raybiotech ELISA method achieves competing sensitivity within a 6 hour processing time.
Immuno-PCR IQELISA
The IQELISA and BIQ-ELISA are immuno-PCR assays that combine the specificity and ease of use of an ELISA with the sensitivity of real-time PCR (RT-PCR, also referred to as quantitative PCR or qPCR), providing you with a detection platform that uses familiar ELISA workflows while pushing the frontiers of your detection limits and sample volume requirements.
Ligand Bridging ELISA
Bridging ELISAs are a type of sandwich ELISA designed for detection of antigens with 2 or more identical binding sites, resulting in the formation of a "bridge" complex. This format is commonly used for quantification of therapeutic antibodies; additionally, anti-drug antibodies resulting from immune response to a drug can be detected. The bridging ELISA technique is ideally suited for the development of drug antibodies (DA), since it enables pharmacokinetic characterization as well as detection of immunogenicity.
