Lentiviral Barcode Libraries

Libraries of Unique Barcodes for Clonal Cell Analysis

  • Identify cell sub-populations with advantageous phenotypes for growth or survival
  • Assess changes in cell culture heterogeneity over time or changing culture conditions
  • Track clonal expansion in tumours or during differentiation or metastasis
  • Link CRISPR-induced genetic knockouts with changes in expression profiles

The ability to label and trace individual cells is a powerful experimental tool in many research areas including cell development, tumor evolution, stem cell differentiation, or carcinogenesis. Cellecta’s expressed barcode libraries, together with next-generation sequencing (NGS) technology, enable tracking of clonal variations in large cell populations.

Using Cellecta’s CloneTracker Barcode Libraries, it is possible to genomically label each cell with a uniquely identifiable short nucleotide sequence (i.e., a barcode). Since the barcodes genomically
integrate, they are heritable so all progeny from each cell harbours the same unique sequence and clonal expansion for each founder cell can be monitored.

The initial transduction of a lentiviral barcode library (Figure 1) into cultured cells, produces a founder or starter population in which each cell has a unique and heritable barcode label. NGS can then be used to sort out sub-populations of progeny cells derived from the original progenitors at any point during an experiment. The approach provides a convenient way to identify cell variations with unique characteristics or biology, and to understand how these groups of variant cells evolve in response to drug treatment, tumor metastasis, or other conditions.

With Cellecta’s new CloneTracker XP Barcode Libraries (Figure 2) the barcode is designed to express on an RNA transcript. As a result, it can be detected by RNA sequencing, as well as DNA sequencing. Researchers can identify which genes are actually activated or shut down in different groups of cells. They can identify genes that are important for drug resistance, metastasis, cell differentiation, or other processes.” The CloneTracker XP™ Expressed Barcode libraries are available with barcodes expressed in the 3′- or 5′-UTR of an RNA transcript, and with fluorescent or chemiluminescent reporters.
