Experiment / E97VTAV9CEpisomal Plasmid MPRA

5′ MPRA sub-tiling v1 in PYS-2 cells

Multi-scale dissection, compaction and derivatization of mammalian developmental enhancers

A 270 bp, 5 bp-stride sub-tiling library covering ten developmental CRE intervals was assayed in PYS-2 parietal endoderm-like mouse cells.

Processed tables are specific to each experiment. Column names, units, measurements, and table structure are not standardized across the database. Check this experiment’s column definitions and quality-control notes before comparing or combining data.

Perturbation & assay details

Basal / Untreated

5′ episomal plasmid MPRA using the p001-PB-MPRA/minP reporter with a degenerate barcode in the reporter 5′ UTR; RNA and DNA barcode UMIs were sequenced separately and activity was quantified as a normalized 1% Winsorized RNA/DNA ratio.

Quality control

Author-processed activity tables already applied the DNA-UMI >=2 barcode filter and 1% Winsorization. Package QC retained finite non-negative activity entries with >=5 barcodes per replicate and >=3 QC-passing biological replicates per construct; mean and SD are across retained replicates. Final table contains 1330 constructs.

Curation notes

PYS-2 is ATCC CRL-2745 and Cellosaurus CVCL_3776; source includes ten original CREs and controls.
