Improve assay sensitivity and specificity with Locked Nucleic Acid oligonucleotides (LNA oligos) from LGC Biosearch Technologies. LNAs are RNA bases in which the ribose is “locked” with a methylene bridge, fixing the base in the C3’-endo conformation.

Benefits of LNA Probes

LNAs enable a shorter probe design, supporting the assay design for:

  • Improved assay sensitivity
    • Higher quenching efficiency (lower background)
    • Greater signal-to-noise ratio
  • Increased hybridization specificity
  • Targeting AT-rich sequences
  • Better mismatch discrimination in SNP genotyping assays

LNAs for commercial use

You can maximize assay performance by harnessing the combined power of LNA technology and best-in-class BHQ quenchers. The Biosearch Technologies team is ready to help you optimize your assay. Provide the manufacturing team with your precise instructions using this Excel template today. 

Additional advantages:

  • Access LNA probes for multiplexing with a full suite of fluorophores.
  • Insert up to seven LNA bases in the probe sequence.
  • Purified via DUAL-HPLC and sequence verified via uHPLC and MS.

Save time and resources with pre-mixed LNA probes and primers

Ordering LNA probe and primer pairs as a ValuMix assay simplifies the assay setup process.

You can supply the specifications, including the probe-to-primer ratio, for gene expression and qPCR assays, and LGC sends you a unique, dual-labeled LNA probe and primer pair in a single tube.

LGC Biosearch Technologies provides a ValuMix assay for SNP genotyping applications that consists of two custom LNA probes and a primer pair delivered in exact quantities.

Customize your LNA oligo with an extensive menu of modifications

Take advantage of LNA-enhanced oligos, for example with your primers for added specificity in SYBR Green Assays. LGC Biosearch Technologies can synthesize custom oligos with internal LNA modifications. Simply add a "+" sign in front of the base to designate the LNA-base position (+A, +T, +C, +G) and insert up to 20 LNA bases.
