This optimized FluoroSpot assay reliably detects mouse IgM secretions from either antibody secreting cells that have been immunized/activated in vivo, or memory B cells that have been polyclonally stimulated in vitro to secrete antibody.
This ImmunoSpot® kits contains low autofluorescence PVDF plates, diluents, capture antibody, detection reagents and a polyclonal B cell stimulator (Mouse B-Poly-S™) that promotes differentiation of B cells into antibody-secreting cells (ASC) capable of producing IgA, IgG or IgM.
