Watermelon Library
(Pooled Library #155257)

  • Purpose

    The Watermelon library is a high complexity lentiviral barcode library for simultaneous tracing of clonal lineages as well as the transcriptional and proliferative state of each cell in the population. Lineage tracing is achieved by mapping a clone-specific expressed DNA barcode in the 3′ untranslated region of an mNeonGreen protein, and proliferation history is monitored by the dilution of a doxycycline (dox)-inducible H2B-mCherry transgene.

The data and code related to this library is available on GitHub.

The file "Watermelon Library Sequence (Primers marked)" linked above provides an example of the plasmid sequence. Please see the Nature publication section "Cloning of the Watermelon library" to see how the final sequence compares to the Watermelon backbone (Plasmid #155258).

NOTE: Lentiviral vectors can recombine during library amplification, resulting in a ~6 kb and ~3.5 kb band. The recombined backbone product should not adversely affect library function as it does not contain lentiviral packaging sequences. If these additional bands represent a large percentage of the product after amplification, we recommend starting with a larger prep (gigaprep) from the original sample or gel purifying the amplified library to remove the recombinant band and performing another transformation with the purified sample.
