Pierce STAT3 Near Infrared In-Cell ELISA Kit Each for $511.50


Thermo Scientific™ Pierce STAT3 In-Cell ELISA Kits are colorimetric and fluorescent microplate assays optimized to measure total and phosphorylated signal transducers and activators of transcription 3 (phospho-STAT3) in whole cells.

Pierce STAT3 In-Cell ELISA Kits enable the relative quantitation of total and phosphorylated signal transducers and activators of transcription 3 (STAT3) in whole cells using a 96- or 384-well microplate format. The complete kits include a mouse monoclonal anti-STAT3 antibody, rabbit monoclonal anti-phospho-(Tyr705) STAT3 antibody, detection reagents and all buffers required for either colorimetric or near infrared detection.

The Colorimetric In-cell ELISA Kit facilitates comparison of multiple target protein levels from different wells using target-specific antibodies, HRP-conjugated detection reagents and TMB substrate. Results across wells are then normalized to cell number based on whole-cell staining with Janus Green.

The Near Infrared In-Cell ELISA Kit allows simultaneous detection of two different target proteins within the same well, eliminating variability caused by differences in cell plating. With the near IR system, protein levels are determined by using target-specific primary antibodies and DyLight™ Fluor-Conjugated Secondary Antibodies. The near IR detection method eliminates issues with background fluorescence, providing a high signal-to-noise ratio and making these fluorescent multiplex experiments both sensitive and robust.


  • In-cell ELISA – target-specific detection directly from plated whole cells; no cell lysis, protein extraction or special sample preparation required

  • Quantitative and specific – system provides accurate measurement of relative protein expression levels in treated vs. nontreated cells

  • Better than Western blotting – In-cell ELISA directly yields quantitative results and provides higher throughput than Western blotting techniques

  • Less expensive – costs less (one well vs. one lane) than Western blotting methods of protein expression and activation analysis

  • Multiplex-capable – replicate wells or different fluors enable multiple ELISA targets to be measured relative to the primary targets supplied with the kit

  • Two kit formats – choose the colorimetric kit for use with standard microplate readers; choose the near infrared fluorescent detection kit for use with IR imaging systems
