Product Overview:
Enzyme ImmunoAssay (EIA) is a technique to detect and quantify antigens (proteins, hormones…) or antibodies in samples. It relies on the ability of an antibody to bind a specific antigen. Either the antibody or the antigen is labelled with an enzyme whose substrate is a chromogen or a fluorogen converted in a measurable product (color or fluorescence).
Enzyme-linked Immunosorbent Assay (ELISA) is a type of EIA using a solid phase (ex: microtiter plate) coated with an antigen immobilizing the molecule to detect. Over the time, scientists have extended the term ELISA to EIAs using an antibody coating the solid phase. That explains why our EIA kits using coated antibodies are also called ELISA kits.
Bertin Bioreagent offers a totally new set of assays to measure Acylated & Unacylated Ghrelin, whatever the collection procedure.
Those assays are called Easy Sampling EIA kit because any blood sample collected can be used on any kind of protease inhibitors with or without acidification. From early discovery programs using our 384 wells plate format to select your GOAT inhibitor, to the pre-clinical or clinical stage, Bertin Bioreagent has a solution.
