    Search Tips

    Looking for predesigned RNAi, gene expression, or gene editing products to target your gene of interest? Simply enter a gene identifier in the Search box above!

    When searching for a gene-specific product, it is best to use only biological terms in your search. Below is a table of common gene identifiers that can be used. If you have used the site search at the top of the page, you can find gene-specific product by first locating the gene of interest in the "Genes" section of the results. Once you have selected your gene, all available products will be listed. You can choose a category for the type of product and then filter your results by species, product line, vector type, or other product features if desired.

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

    Gene-based search terms

    Identifier Description Examples
    Gene ID The 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 Number Accession 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 Symbol The Gene Symbol can be the official or alternate symbol as displayed on NCBI Gene.
    • BRCA1
    • CDK1
    • CTNNB1
    Gene Description The Gene Description is also known as the Official Full Name on NCBI Gene.
    • myogenic differentiation 1
    • thyroid peroxidase
    • breast cancer 1, early onset
    miRBase Identifiers miRBase 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

    Searching by catalog number

    You can search by catalog number to find a specific product quickly and add it to your cart without leaving the search results page. Please note that the catalog number must be complete and an exact match to return any results. For example, if your product has a size designation as part of the catalog number, this must be included in your search term.

    Note: If you have a large number of items to add to your cart, this can be done more quickly using the Quick Cart tool linked from the top of the page.

    Searching for technical documents

    You can find technical documents in several ways. First, you can use the main search at the top of the page and look for results in the "Resources" section. Second, you can use the Resources to search for documents by product type or browse by document type. Finally, all documents relevant to a given product can be found on the product page under the "Resources" tab.

    General search tips

    Search for items containing multiple words:

    • miRNA Hairpin Inhibitor Controls

    • Human siRNA libraries

    Search for either word:

    • Use "or" between words to find pages that have one of several words.

      • siRNA or Human

    Search for Product Numbers:

    • T-2004-01

    • T-2004* to find catalog numbers starting with "T-2004" (i.e., T-2004-1. T-2004-2, T-2004-3, T-2004-4)
