Oligo modifications

The range of modifications IDT offers is unmatched within the industry. Browse their catalog on oligo modifications for detailed information on the available modifications, or contact us if you cannot find what you need.

CRISPR genome editing

Use of the CRISPR (clustered regularly interspaced short palindromic repeats) and associated Cas9 enzyme for genome editing has been a major technological breakthrough, making genome modification in cells and organisms faster, more efficient, and more robust than previous genome editing methods. The Alt-R CRISPR-Cas9 System is an optimized genome editing solution that outperforms other CRISPR approaches for producing on-target, double-stranded DNA breaks.

Alt-R CRISPR-Cas9 system

Efficient CRISPR reagents based on the commonly used Streptococcus pyogenes Cas9 system for lipofection or electroporation experiments. Protospacer adjacent motif (PAM) = NGG. More on the Alt-R CRISPR-Cas9 system

Alt-R CRISPR-Cas12a system

The Alt-R CRISPR-Cas12a (Cpf1) system is an alternative developed by IDT to open up CRISPR editing to organisms with AT-rich genomes and to additional areas in genomes which are not available to the Cas9 system. More on the Alt-R CRISPR-Cas12a system

CRISPR nucleases

Recombinant, high-purity Cas9 and Cas12a (Cpf1) endonucleases for genome editing experiments. More on available CRISPR enzymes

Genome editing detection

T7 endonuclease I (T7EI) mismatch cleavage assay is used for the detection of on-target editing, known off-target events, and estimation of genome editing efficiency in CRISPR-treated cells. More on the genome editing detection kit

Genes & gene fragments

Single- and double-stranded DNA fragments and cloned genes for synthetic biology and other molecular biology applications

IDT's high-fidelity synthetic genes and gene fragments are the result of a long-standing commitment to innovative chemistry, optimized methods, and a robust manufacturing infrastructure. These products are built using their Ultramer® DNA Oligos, which set the standard for quality within the industry, and every gene or gene fragment you receive shares or exceeds that consistently high quality.

Next generation sequencing (NGS)

Adapters and xGen® capture

Next generation sequencing (NGS) technologies are rapidly becoming an integral part of genetic research and discovery. The ability to generate large amounts of sequence data in a relatively short amount of time enables a wide range of genetic analysis applications and accelerates advances in research, clinical and applied markets.

Critical to the success of obtaining high quality results in NGS experiments is the availability of high quality tools to effectively prepare fragment libraries representing the original nucleic acid samples. From platform adapters to their portfolio of xGen® products for targeted sequencing, IDT’s mission is to deliver innovative, high performing NGS products to enable you to increase your discovery power.

Adapters for next generation sequencing platforms

IDT manufactures custom and catalog adapters for any NGS platform. Choose from a variety of barcoding and error correcting strategies, including designs with unique dual index (UDI) barcodes and unique molecular indicators (UMIs)More on IDT's NGS adapters

A suite of high performing enrichment probes, blockers and workflow reagents for targeted sequencing. The xGen® product portfolio enables unparalleled target coverage and uniformity, even across difficult genomic regions containing high GC content. More on xGen® hybridization capture

qPCR and PCR

Over several decades, IDT has refined a proprietary platform improving nucleotide coupling efficiency during oligo synthesis. Subsequent purification steps ensure high quality primers/probes for consistent PCR and qPCR performance. All oligos are QC tested in-house by ESI mass spectroscopy to ensure an accurate, full length, final product.

Gene expression

Choose from probe- or intercalating dye–based qPCR options across a flexible, user-defined product offering. PrimeTime®products for gene expression are created to work well together, but can also be ordered and used separately. This modular system includes predesigned or custom assays, custom probes, master mix, and design tools. More on PrimeTime® for gene expression
