Dual secreted Alkaline Phosphatase and Luciferase detection in one sample

Secrete-Pair™ dual luminescence assay kit analyzes the activities of Gaussia Luciferase (GLuc) and Secreted Alkaline Phosphatase (SEAP) as a dual-reporter system. This dual luminescence assay system includes all reagents needed for an optimal dual luminicent detection of GLuc and SEAP while allowing transfection normalization and side-by-side analysis using the same sample from the cell culture medium.

With Secrete-Pair™ dual luminescence assay kit (GeneCopoeia), samples can be easily obtained from cell culture medium without lysis of the cells.

  • Dual-reporter detection
  • No cell lysis necessary
  • Real-time and fast data generation

Unique formation for robust and high sensitivity luminescence detection

  • Two buffer conditions are provided for GLuc assays:
    • Buffer GL-S with a stabilizer to overcome the quick decay of the GLuc signal.
    • Buffer GL-H with a specific formulation When higher sensitivity is required for detecting low expression of GLuc.
  • Optimized buffer for stable activity – 90+% of signal retained within the first 10 minutes and extends the half-life of light emission to approximately 30 minutes
  • Higher sensitivity – Ideal to detect low GLuc expression

Robust GLuc and SEAP data

  • Transfection normalization:
    • True cross-sample comparison
    • GLuc activities can be compared across samples free of the impact of transfection variation.
  • High-throughput compatible – high sample number compatible
