Elispot assay ( assay to determine cytokine producing cells)

The enzyme-linked immunospot (ELISpot) assay is a highly sensitive immunoassay that measures the frequency of cytokine-secreting cells at the single-cell level. In this assay, cells are cultured on a surface coated with a specific capture antibody in the presence or absence of stimuli.

Really nice video. It let us know both, things common between ELISA and elispot and also what makes them different from each other. Such animations in your videos are always helpful to remember things in a better way.

Very good animation. U forgot to mention abt stimuli. U need to add stimuli so that it will stimulate the cell to produce cytokines.

What is the advantage here in comparison to flow cytometry? In flow cytometry we do not look for "shadows" after cells, but we can actually count how many Th17 cells are there and it is much easier and faster than Elispot. Also in Elispots we do have SFUs often and it is hard to say how many cells were really there. I just don't understand why not just using flow cytometry? If someone uses PBMCs they won't know which cell really produced IFN (many do it) so Elispot will show in this case only shade of a cytokine and not the producing cells (we won't know which cell produced IFN in such case). An honest question, because I am new to Elispots and old to flow ;) I found my answer: "Flow cytometry can determine the number of cells that produce IFNγ, but not their secretory activity and the amount secreted by them. ELISPOT quantifies the frequency of IFNγ-secreting cells, but not the number of producing cells nor does it measure the amount of IFNγ secreted from cells."

[@animatedbiologywitharpan]

The only benefit for this technique is the low cost compared to flowcytometry

That depends .....generally these center's deals with infection and immune systems...its there in NII Delhi

[@sristi_2360]

Can you please clear a doubt? One cell can produce many molecules of cytokines which can subsequently bind to more than one capture antibody, and hence produce more than one spot. So why is it that one spot equals to one cell?

[@animatedbiologywitharpan]

Good question....email me your contact we can chat in WhatsApp...too much to write in a comment

[@sristi_2360]

@@animatedbiologywitharpan your email?

[@olamarca7171]

I also don't understand. Can someone explain this? How do you know that the certain spot is from a different cell. Can be from different amount of a cytokine produced by the same cell.

[@everydaynabil1937]

@@olamarca7171 i think its because, each cell produce lots of cytokines and these cytokines will bind to nearest antibody. The cytokines naturally will diffuse in a small circular radius around that singular cell. Then, in this small circular area around the singular cell, the antibodies binded with cytokine will form complexes with secondary enzyme - and due to their very high concentration of complexes in that small circular radius around the singular cell, we see a single spot. Hence why one spot is from one cell.

Sir....could u plz clear my doubt
ELISPOT is used for measuring cytokines or the secretory cells like T-cells??

jabi fatma cytokines secreting cells are detected using this assay.....for cytokines only ELISA is enough
