ELISA
Introduction Among all the ligand bioassays developed, the one which has emerged victorious is the Enzyme Linked Immuno Assay, or ELISA. Variations of the ELISA now have to power to discriminate antigens down to the femtomole/femtogramme (10-18 of a kilogramme) level, depending on how it’s implemented, offering researchers unprecedented levels of sensitivity. Furthermore, ELISA could harness … Read more
