Choosing Your Immunoassay: ELISA vs. ELISpot

What is an ELISA assay? An ELISA is a plate-based immunoassay used to detect and quantify specific proteins in liquid samples such as serum, plasma, or cell culture supernatants. ELISAs translate antibody–target binding into a measurable signal using an enzyme “reporter” that generates a colour change or a chemiluminescent/fluorescent readout. In most ELISA formats, the […]

The Immune System and the Role of T Cells

By Dr Clément Monteil When the human body encounters an external infection such as a virus, bacteria or parasite, it activates a complex and coordinated defence mechanism to identify, target and eliminate the invading pathogen. This response is managed by the immune system, an elaborate network consisting of cells, organs, and molecules, designed to protect […]
