LCT -13910C>T RealFast® Assay

The LCT -13910C>T RealFast™ Assay is a fast and accurate real-time PCR test for the detection of the LCT -13910C>T variant in the upstream regulatory region of the lactase (LCT) gene. The kit is designed to identify patients with the LCT -13910CC genotype, which causes lactase non-persistence and thus intolerance to dietary lactose. The qualitative assay discriminates the three possible LCT -13910C>T genotypes in a human DNA extract: CC (non-persistent),

  • Kits are based on reverse-hybridization of biotinylated PCR products.
  • Minimal equipment required (thermal cycler, shaking water bath).
  • Technology combines probes for mutations and controls in a parallel array of allele-specific oligonucleotides.
  • Functions using immobilized oligos on a teststrip.
  • Strips show mutations by enzymatic color reaction visible to the naked eye.
  • Proprietary software package (Evaluator™) that aids in data interpretation, storage, and archiving.
