CytoSelect 细胞增殖分析试剂(比色法)产品建议保存条件是CytoSelect Cell Proliferation Assay Reagent (Colorimetric) is a clear, slightly red, ready-to-use solution and should be stored at 4°C. If precipitates or turbidity are observed upon thawing, warm the solution to 37°C for 5–10 minutes and agitate to dissolve the precipitates. For longer periods, aliquot and store at –20°C protected from light to avoid repeated freeze-thaw cycles.
