Just running a dual fluorospot IgG/IgM and can confirm spots using ELISpot but when I run Fluorospot for the same, I only have responses in the total IgG/IgM wells

Any help please

Hi Eunice

I will gladly help you with you.

However, I think that I need some more information about you assay first.

As I understand it you are seeing antigen-specific IgG and IgM spots in ELISpot, but not in FluoroSpot when you run a dual IgG/IgM assay? Is that right?

Since you see IgG and IgM spots in the total wells, there seems to be no problem with the detection antibodies or the cells.

Please provide some more info on the protocols (you dont have to share specifics, only the general protocol that you use).

Best regards

Peter
