B-Poly-S™ Peptide Antigen Solution

B-Poly-S™ Polyclonal B Cell Activator

In B cell ELISPOT and FluoroSpot assays, four-day prestimulation cultures are recommended for most in vitro ASC measurements (CTL Human B-Poly-S™ and CTL Murine B-Poly-S™), and seven days for human IgE (CTL Human B-Poly-SE™). Both CTL Human and Murine B-Poly-S™ have been shown to provide optimal polyclonal stimulation of memory B cells.

The amount of CTL B-Poly-S™ provided is sufficient for stimulation of 320 million PBMC at 4 million cells/ml.

Concentration: CTL B-Poly-S™ (Human and Murine) — 1,000x; CTL B-Poly-S™ (IgE) — 200x
