B-Poly-S™ Polyclonal B cell Stimulator

Memory B cells exist in a quiescent state in the absence of recent antigen encounter and importantly do not secrete their individual BCR as soluble antibody. Therefore, polyclonal stimulation of resting memory B cell is required for their measurement using ELISPOT or FluoroSpot (collectively ImmunoSpot®). Mouse B-Poly-S™ promotes polyclonal stimulation and differentiation of B cells into antibody-secreting cells (ASC) capable of producing IgA, IgG or IgM.
