What is Elispot and why is it important?
Elispot is a technique that allows you to measure the frequency of cells that secrete a specific protein, such as a cytokine or an antibody. It is based on the principle of capturing the secreted protein on a membrane coated with a specific antibody, and then detecting it with another antibody that produces a visible spot. Each spot corresponds to one secreting cell, so you can count the number of cells that produce a certain protein in response to a stimulus.
Elispot is a powerful tool for studying immune responses, such as infection, vaccination, allergy, autoimmunity, transplantation, and cancer. It can help you identify rare antigen-specific cells, quantify their functional activity, compare different populations or conditions, and monitor changes over time. Elispot is also suitable for clinical applications, such as diagnosis, prognosis, and therapy evaluation.
What is Image J and how can it be used for Elispot image analysis?
Image J is a software that allows you to process and analyze scientific images.
