The Enzyme Linked Immunosorbent Assay (ELISA) is one of the most effective tools available for detecting and quantifying a given antigen in a complex sample. While it is possible to create ELISAs from scratch for your antigen of interest it is often more effective (from both a time and cost perspective) to simply purchase an ELISA from a supplier that has already worked out the conditions for you. There are a wide range of pre-made ELISAs on the market so there is a good chance that you can find the one you need for your experiments. Take a look below at the latest in ELISA Kits and the equipment to interpret them.
