IL-21 (human), lyophilized (AlphaLISA)

Human IL-21 standard, for use in running standard curves in AlphaLISA assays. This standard is already provided in the AlphaLISA human IL-21 Detection Kit, but can also be ordered separately..This standard should be reconstituted in 100 µL Milli-Q® grade water. The reconstituted analyte should be used within 60 minutes or aliquoted into screw-capped polypropylene vials and stored at -20°C for further experiments. Avoid multiple freeze-thaw cycles. One vial contains an amount of analyte sufficient for performing 10 standard curves..
