I please need to know how long I should keep vaccinated mice after administering the final booster dose before performing ELISPOT to check for the presence of memory B cells from their harvested spleen.
In my experience, it is usually 7-14 days after booster injection. To be accurate, you may check for antigen-specific antibody response after post-treatment. If there is sustained or heightened antibody response, the presence of memory B cells are pretty much confirmed. Hope this helps. All the best!
