ORF Collections

For fast and simple gene overexpression

Precision LentiORFs

Precision LentiORFs are expression-ready open reading frames (ORFs) that have been cloned into a lentiviral expression vector with a GFP reporter.

CCSB Human ORFeome Collection

Gateway® adapted human entry ORFs are ideal for easily moving entire families of ORFs into your choice of protein expression systems.

CCSB-Broad Lentiviral Expression Collection

Human ORFS in a lentiviral vector, stop codons have been removed and clones contain a C-terminal V5 tag.

ORFeome Collaboration Clones

ORFeome Collaboration clones are sequence-verified, human open reading frames (ORFs) subcloned into Gateway® recombinational entry vectors.

hORFeome v8.1 Collection

This fully-sequenced collection of Gateway-adapted ORFs represents the latest version of the CCSB Human ORFeome library from Dana-Farber Cancer Institute.

Non-mamalian cDNAs and ORFs

Overexpress genes from Yeast, C. elegans, E. coli, Zebrafish or Xenopus laevis.

RNAi Rescue using Precision LentiORF

The Precision LentiORF collection provides a comprehensive set of ready-to-use clones that permit RNAi rescue in studies that utilize 3'-UTR siRNA reagents. This study highlights the necessary controls and optimization required for an RNAi rescue experiment and demonstrates the utility of these constructs when validating phenotypes associated with siRNA-mediated silencing.

Top five considerations for ORF selection

Five tips to quickly and effortlessly select the right clone format for your over-expression project.

Using ORFs with variable stop positions

Many Precision LentiORF clones are available either with or without the native stop codon.
