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

RCE1182 glycerol stock - $115.00select
Derived from the C. elegans ORFeome Library v1.1, the C. elegans RNAi collection provides comprehensive coverage for screening with over 11,000 RNAi clones. These constructs are cloned into the pL4440-dest-RNAi Destination vector and are archived as glycerol stocks of the E. coli feeding strain HT115(DE3). Minipreps of this DNA can be used as templates for in vitro dsRNA synthesis before RNAi application by soaking or injection.


  • Coverage - C. elegans RNAi collection contains over 11,000 RNAi clones
  • Feeding ready format - after being cloned into the feeding vector PL4440, the cloned ORFs have been transformed into the RNAi feeding bacterial strain HT115(DE3)
  • RNAi versatility -  plasmid preps of the ORF-RNAi clones can be used as templates for in vitro dsRNA synthesis for soaking or injection

We provide certain clone resources developed by leading academic laboratories. Many of these resources address the needs of specialized research communities not served by other commercial entities. In order to provide these as a public resource, we depend on the contributing academic laboratories for quality control.

Therefore, these are distributed in the format provided by the contributing institution "as is" with no additional product validation or guarantee. We are not responsible for any errors or performance issues. Additional information can be found in the product manual as well as in associated published articles (if available). Alternatively, the source academic institution can be contacted directly for troubleshooting.
