Primary Antibodies

Antibodies are often the main ingredient to many widely-used laboratory applications, such as Western Blots (WB), Enzyme-Linked Immunosorbent Assays (ELISA), Immunohistochemistry (IHC), Immunocytochemistry (ICC), Immunoprecipitation (IP), and Flow Cytometry (FACS). In arigo, we mean quality and make it our first priority to provide high quality products to the research community. To this end, we screen our antibodies and validate them with scientific approaches to determine the specificity of our products.

Sandwich ELISA is a sensitive and accurate way of quantifying antigen concentration in a certain sample type. It is named sandwich ELISA because the antigen of interest is captured by two different antibodies which target the different epitopes within the same protein. The concentration is then quantified by measuring the color change caused by the enzymatic reactions using a spectrometer.
