Intermediate scale
oligonucleotides
|
| •
|
Scale: Synthesis scales range from 10
µmol to several mmol. This corresponds
with quantities of 10 mg to several grams.
|
| •
|
Purity: Our standard purity > 95%,
purities of 99 % as determined by analytical
HPLC are available on request.We have
completely optimized purification methods
customized for each oligo depending on its
length, its likeliness to form secondary
structures, the purity requirement and the
required counterion.
|
| •
|
Yield: Our expertise in the field of
nucleotide and nucleoside chemistry enables us
to perform oligonucleotide synthesis with the
highest yield in a cost effective format. For
more info click complexity and cost
efficiency.
|
| •
|
Standard RNA & DNA: In our
portfolio we have the above mentioned scales
of standard RNA and DNA oligos. RNA oligos up
to lengths of 45 bases are standard. For
longer RNA oligos, please inquire.

of complex chimeras and aptamers containing
almost any commercially available monomer is
also offered.

RNA - Peptide conjugates
|
The cellular uptake of oligonucleotides in
vivo is a fundamental issue that has
challenged scientists in the antisense field
and is now a major issue for the in vivo /
therapeutic application of siRNA.
It has been demonstrated that a variety of
peptides enhance cellular uptake of
oligonucleotides when conjugated to them, thus
avoiding the usage of liposomes, many of which
are toxic in vivo.
RNA-TEC now offers custom synthesis of
RNA-peptide conjugates in which the linkage
between the oligo and the peptide is stable or
biodegradable.
|
Custom synthesis
|
| •
|
Custom synthesis of various nucleotide related
complex molecules e.g. aminoacyl adenylate
analogues as inhibitors of aminoacyl t-RNA
synthetases. Various research programs are
supplied with complex molecules, but are
confidential.

We are very pleased to offer
5´-O-[N-(L-aminoacyl)sulfamoyl]adenosines
for sale as stable analogues of aminoacyl
adenylates. These compounds have the general
structure shown below, where R represents an amino
acid side-chain, and are potent inhibitors of the
corresponding aminoacyl-tRNA synthetases. To date the alanyl (1-3), arginyl (4), asparaginyl (5, 24), aspartyl (13), cysteinyl (3), glutaminyl (6, 7), glutamyl (14), glycyl (1, 15), histidyl (4, 8), isoleucyl (21), lysyl (9), prolyl (3, 10, 16), seryl (11, 17), threonyl (4, 12, 18, 19), tyrosyl (20, 23) and valyl (22) analogues have been described in publications.

We envisage that these compounds should be of
general interest to all scientists working on
aminoacyl-tRNA synthetases.
Of course we would be very happy to custom
synthesize other analogues such as norvalyl, so
please contact us for a quotation.
