R&D Systems™ Human TGF-beta Panel Luminex™ Performance Control

Intended Use & Description

For use as quantitative controls for the determination of human cytokine concentrations in biological fluids. Concentrations have been assigned using R&D Systems™ Luminex™ High Performance Assays. Controls are prepared in a buffered protein solution with preservatives. They contain recombinant human cytokines at low, medium and high concentrations. Controls are supplied lyophilized.

Storage & Stability

Unreconstituted Controls should be stored at 2-8°C and are stable for at least 6 months from date of receipt. Depending on the analyte of interest, reconstituted controls may be stable when stored at < -20°C. Users should evaluate the frozen stability of the controls in their application or discard after use.

Reagent Preparation

Reconstitute each vial with the volume of Calibrator Diluent indicated on the product datasheet.

Procedure & Expected Values

Controls should be assayed in the same manner as unknown specimens.

The acceptable ranges for the analytes in these controls are printed on the product datasheet. Due to possible variations in techniques and methodologies, it is recommended that each laboratory determine its own target range. Laboratories using other test systems should establish their own acceptable ranges as these assays may produce different values.
