Custom synthesis and pre-designed formats to meet your specifications

We provide a complete range of custom-synthesized oligonucleotide primers, probes, and genes, all built to your specifications. With options suitable for PCR, cloning, hybridization, real-time PCR assays, protein expression, and more. Our easy-to-use online ordering tools and convenient delivery times keep your research moving. Invitrogen®, Applied Biosystems®, TaqMan®, GeneArt® synthesis services offer the quality, reliability, and convenience you expect.

In addition to custom oligos, we also offer predesigned primer/probe sets for TaqMan® Assays, Ambion® Silencer Select siRNA & Stealth RNAi™ siRNA for RNA interference studies, as well as general use oligos and hybridization probes.

Choose from standard deoxynucleotides, modified bases, and 5' and 3'-modified nucleotides, our Invitrogen® custom oligos can be ordered in 5 quantities and 4 purity levels to help meet all your application needs.

Choose from dual-labeled TaqMan® probes, 5’ fluorescently-labeled single primers, labeled primer pairs for fragment analysis, gene expression, PCR, and genotyping, and unlabeled sequence detection primers.

For gene expression, SNP genotyping, copy number variation, mutation detection and more, you can use our assay search tool to find single-tube TaqMan® Assays. SYBR® Green dye-based expression detection is also available.

Obtain the exact gene sequence you need in the vector of your choice, with rapid synthesis and assembly. Use our optional GeneOptimizer software for maximized protein yield and excellent accuracy.

Synthetic ready-to-clone Strings™ DNA Fragments up to 3 kb are processed within 5 to 8 business days, depending on length. Flexible and affordable, with easy online ordering tools for optimizing your fragments.

Design your own Invitrogen® custom RNAi oligos, or search our database for pre-designed and bench-tested RNAi sequences. RNA oligos are supplied in 96-well plates, with easy re-ordering options to save you time.
