Custom LNA
Custom LNA
(Lock Nucleic Acid Synthesis), Locked Nucleic Acid (LNA) was first described by Wengel and co-workers in 1998 as a novel class of conformationally restricted oligonucleotide analogues. LNA is a bicyclic nucleic acid where a ribonucleoside is linked between the 2'-oxygen and the 4'-carbon atoms via a methylene unit.
Oligonucleotides containing LNA exhibit unprecedented thermal stability towards complementary DNA and RNA2, which allows excellent mismatch discrimination. In fact, the high binding affinity of LNA oligos is recommended for use in any hybridization assay that requires high specificity and/or reproducibility such as
All LNA oligo synthesis include/are:
Labeled probes
In situ hybridization probe
SNP genotyping
DNA MicroArray expression analysis
Allele Specific PNA
mRNA sample preparation
Molecular Beacons and PCR primers
LNA Chimeras
As a result of these significant characteristics, the use of LNA-modified oligos in antisense drug development is now coming under investigation4 and, recently, the therapeutic potential of LNA has been reviewed.5
BSI offers LNA synthesis with great flexibility. For more information on custom LNA synthesis, call 800-227-0627 or write to us at biosyn@biosyn.com

About BSI
"The use of state-of-the art technology has allowed Bio-Synthesis, Inc. to rapidly gain recognition for its manufacturing quality & dependability of delivery."
Founded in 1984, Bio-Synthesis, Inc. was first known as OCS Laboratories. It was the first producer of commercially available synthetic DNA and, in 1985, became a producer of synthetic peptides. In 1989, OCS incorporated as Bio-Synthesis, Inc. and moved its laboratories to Lewisville, Texas. Today, BSI occupies 10,000 square feet of modern laboratory space (completed in 1995) located 20 miles from downtown Dallas and 10 miles from D/FW airport. Among the surrounding academic institutions are: University of Texas Southwestern Medical School (12 miles), University of North Texas (10 miles), and University of North Texas Health Science Center (25 miles). These universities provide excellent library resources. Since its inception, BSI has steadily expanded its product lines and services to meet the growing needs of the molecular biology community. It has maintained its position as an aggressive, innovative company in a highly competitive marketplace without sacrificing quality. In the beginning, our primary emphasis was on synthesizing high quality DNA primers and linkers, which were the initial uses of oligos. Today, newer technologies, such as gene construction, PCR, mutagenesis, combinatorial libraries, dye/adduct labeling, DNA microarrays, peptide-nucleic acid chimeras, etc. have challenged the molecular biology field. In response, BSI has branched into several related areas including DNA paternity testing, DNA HLA typing, PNA synthesis, genomic sequencing, fluorescence-based genotyping, custom organic synthesis and other molecular biology based applications.
The Research and Development Division comprises a number of Ph.D. and M.D. professionals with backgrounds in molecular biology, immunology, nucleic acids, peptide synthesis, general organic chemistry, and automated amino acid sequencing. The Molecular Biology Division is set up to handle most modern experimental procedures; the Immunology Division specializes in immunodiagnostic-based reagents.
Not only has BSI continued to provide quality DNA products and services for the research community, but it has also become a world leader in providing custom peptide products and services. Using state-of-the-art solid phase peptide chemistries, BSI provides high quality custom peptides, performs carrier conjugations, antipeptide antibody production, antigenic peptide design, synthesis of long and/or modified peptides, MALDI TOF analysis, contract research, consultation services and more.
Biomedical researchers worldwide in universities, biotech companies, private clinics, and government agencies use products from Bio-Synthesis, Inc. in studies ranging from PCR diagnostics to cancer research and the Human Genome Project. Contact us to discover how BSI can customize products/services to suit your research requirements.
