New gene content now available!

Precision LentiORFs are human cDNA open reading frames (ORFs) cloned into a lentiviral expression vector, used for overexpressing human genes and proteins in mammalian cells
Enter a common gene identifier and click SEARCH to find products for your gene

Common gene identifiers for your gene can be found at NCBI Gene or miRBase.

Gene IDThe Gene ID is a unique identifying number for each gene in the RefSeq database and tends to be the most stable gene identifier.
  • 672
  • 22421
Accession NumberAccession Numbers are identifiers for a sequence record. The preferred accession numbers for RNAi products are found in the Reference Sequence (RefSeq) database, a non-redundant, curated, and annotated collection of sequence records for major model organisms. RefSeq accession numbers for mRNA begin with the characters NM_ or XM_ followed by six or nine digits. For gene expression products, the GenBank accession number for the clone can also be used for more specific search results.
  • NM_001798
  • NM_001170537
  • BC068303
Gene SymbolThe Gene Symbol can be the official or alternate symbol as displayed on NCBI Gene.
  • BRCA1
  • CDK1
  • CTNNB1
Gene DescriptionThe Gene Description is also known as the Official Full Name on NCBI Gene.
  • myogenic differentiation 1
  • thyroid peroxidase
  • breast cancer 1, early onset
miRBase IdentifiersmiRBase accession numbers are the most stable identifiers for microRNA. The miRBase ID, or name, may also be used.
  • miRBase ID: hsa-let-7d, mmu-mir-122
  • Precurser Accession: MI0000065, MI0000256
  • Mature Accession: MIMAT0000065, MIMAT0000246

  • Lentiviral ORF constructs require no subcloning for mammalian expression
  • Fully sequenced coding sequences
  • GFP reporter is transported to the nucleus for easy visualization of expression
  • Clones are available with or without native stop codons
  • Available as ready-to-transduce viral particles, glycerol stocks, or LentiORF Starter Kits


Potential applications of Precision LentiORFs include gene overexpression experiments, RNAi rescue (see the RNAi Rescue using Precision LentiORF technical note), and expression of human proteins in mammalian cell lines. Primary and non-dividing cells can be readily transduced with ready-to-use lentiviral particles transfected with Precision LentiORF constructs directly into your cell line. For generating your own viral particles, Trans-Lentiviral ORF packaging kits are also available.


    • Individual Clones – Glycerol Stock
    • Pre-defined gene families - Arrayed glycerol stocks (includes with and without native stop clones)
    • Complete genome-scale collection - Arrayed glycerol stocks (includes with and without native stop clones)
    • Viral Particles – provided as 2 x 25 µL aliquots with a minimum titer of 10^8 TU/mL
    • LentiORF Starter Kits – Choose from transfection kits, transduction kits, and viral particle kits
    • Viral Particles – provided as 2 x 25 µL aliquots with a minimum titer of 10^8 TU/mL

Precision LentiORF Viral Particle starter kits include:

  • Two Precision LentiORF constructs provided as 2 x 25µL aliquots of high-titer viral particles (1 x 10^8 TU/mL)
  • Precision LentiORF RFP control provided as 25 µL of high-titer virus

Precision LentiORF Transduction starter kits include:

  • Two Precision LentiORF constructs
  • Trans-Lentiviral packaging mix sufficient for 10 packaging events
  • Calcium Phosphate transfection reagent
  • Precision LentiORF RFP control

Precision LentiORF Transfection starter kits include:


The Precision LentiORF expression vectors are not compatible with third generation packaging systems. We recommend the Trans-Lentiviral Packaging System for use with these vectors.


GE Healthcare Dharmacon (“Dharmacon”) is a distributor of multiple gene expression clone collections (cDNAs and ORFs). These clone collections were generated by groups outside of Dharmacon and thus the quality of the collections is largely dependent upon what Dharmacon received from these groups. Specific clone information and plate coordinates were provided to Dharmacon by the suppliers of these clone collections. Dharmacon has not sequence verified each individual clone from these collections. These collections and individual clones are distributed "as is" with no additional product validation or guarantees. Dharmacon has established quality procedures to ensure that individual clones are picked from the identified well in a plate, grown on the correct antibiotic, and are free of phage contamination. Due to the quality of the information provided to Dharmacon, the clone you receive might not match the expected clone. If this occurs, please contact Technical Support (

Shelf Life12 Months
Shipping ConditionWet Ice,Dry Ice,Ambient
Storage Condition-80 C

Individual Clones

Clones are provided as a live culture in a 2 mL tube. Each tube contains LB medium supplemented with 8% glycerol and the appropriate antibiotic. Within 2 to 3 business days of receiving your order we will ship your clone at room temperature via express delivery. Store the stock clone at –80°C.

Clone Collections

Orders of 50 clones or greater and stock plates will be provided in 96-well microtiter plates. These will ship on dry-ice via overnight delivery and should be stored at –80°C immediately upon receipt. Please contact our customer service department for a quote and estimated shipping time on bulk orders.

Viral Particles

Due to the inherent complexity of high-titer lentiviral particle production, we estimate a 6 to 8 week turnaround time for these orders.
