Storage: Store refrigerated at 2 - 8°C for up to 7 days. For long-term storage, freeze at -20°C or below. Recommended Usage: Prestimulation of cells for 3-5 days is recommended for most in vitro ASC applications. Following aseptic technique, add 10μl CTL B-Poly-S™ per 10ml of assay medium. An initial cell density of 1-4 x 106/ml is appropriate for splenocytes. If culturing purified B cells, an initial cell density of 2-5 x 104/ml is advised. QC: Each batch is tested for optimum performance in B cell ImmunoSpot assays. Reference: Genestier L, Taillardet M, Mondiere P, Gheit H, Bella C and Defrance T.
