About Molecular Indexing
The Molecular Indexing technology is based on a method called "stochastic labeling" where each and every copy of a DNA molecule, present in a sample, is labeled at random from a large, non-depleting reservoir of diverse oligonucleotide labels or barcodes. DNA molecules of an identical sequence become distinct through unique labeling. The subsequent diversity of the labeled molecules is governed by the statistics of random choice, thus enabling individual molecules to be identified as unique.

The uniquely labeled DNA molecules comprise the library where a unique Molecular Index for every DNA molecule is created. By detecting the number of distinctly labeled targets, the number of copies or molecules of each gene in the original sample can be determined. Since the MolecularIndex is hard-coded into each individual DNA molecule, the sample can be analyzed directly or amplified by PCR or other techniques without introducing biases or errors.

The key advantages of Molecular Indexing technology include:

  • Absolute Digital Quantitation
  • No PCR or Sequencing Bias
  • Non-destructive assay
  • No dead volume or sampling error
