Lu SPECS Library
(Pooled Library #127842)

  • Purpose

    The Synthetic Promoters with Enhanced Cell-state Specificity (SPECS) library enables high-throughput screening and promoter identification.

    Library constructs are composed of tandem repeats of transcription factor binding sites upstream of an adenovirus minimal promoter controlling expression of mKate2.

Lu Lab SPECS Library

Figure 1. Overview of Lu Lab SPECS Library construction and use.

The depositing lab has shared their analysis pipeline in their Github repository (Link opens in a new window).

The Lu Lab has provided two accessory plasmids to accompany the SPECS Library:

NOTE: Lentiviral vectors can recombine during library amplification, resulting in an ~1-1.7 kb band containing the origin and ampicillin resistance cassette. This recombination product should not adversely affect library function as it does not contain lentiviral packaging sequences or the PuroR gene and will not be selected during screening. If this ~1.7 kb band is observed 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.
