bookmark_borderInformation On ELISA service

ELISA (Enzyme-Linked Immunosorbent Assay), is a versatile test technique. Researchers can use antibodies to measure a specific molecule.

In order to detect the signal, the enzyme, such as horseradish peroxidase, is usually either directly or indirectly linked to the antibody. The assay's sensitivity and specificity will depend on the choice of antibodies and the detection method. If you are interested in ELISA service then you can look for the best ELISA services with a fast turnaround time in Pleasanton online.

How we do ELISAs.

Our ELISA service allows us to quantify antibodies and antigens from a variety of virus-infected samples (e.g. cell lysate and tissue from animal and human specimens)

We are committed to offering simple, reliable, and affordable ELISA services for the research community. VRS offers a variety of advanced ELISA services including:

Direct ELISA: Direct ELISA uses an antigen that is immobilized on a multi-well plate. The specific conjugated primary antibody detects the antigen.

Indirect ELISA: indirect ELISA the antigen is immobilized on a multi-well plate. Then, a specific unconjugated secondary antibody detects it. The secondary antibody, which is enzyme-conjugated, is then applied to the primary antibody's host species.

Sandwich ELISA: Sandwich ELISA uses a capture antibody that is immobilized on a multi-well plate. After the sample has been added, a detection antibody is applied. The detection and capture antibodies are specific for antigens with different epitopes.

Competition ELISA (also known as inhibition ELISA): Competition ELISA is where an antigen is immobilized on a multi-well plate, and then incubated using an antibody that has been previously used with the sample-of interest (that must also contain that antigen).

Our ELISA service can measure antibodies or antigens from a variety of virus-infected samples, including cell lysate, tissue, and serum from animal, human, and plant specimens. We are committed to offering simple, reliable, and affordable ELISA services for the research community.
