Single Pass Sequencing:

We provide fast and highly reliable DNA Sequencing Service performed on ABI DNA Analyzer, which provides high quality of sequence analysis data (Phred Score (QV): ≥ 20, Guaranteed read lengths: ≥ 600bp) Please send in an inquiry to us for more information.

Difficult Template Sequencing:

For sequencing of difficult templates which frequently cannot be successfully sequenced under normal sequencing procedures for example:

1. siRNA with hairpin structure
2. G/C rich or A/T rich template
3. Templates with homopolymeric traits
4. Repetitive sequences
5. Secondary structures

16s rRNA and 18s rRNA (ITS region) Sequencing:

It is getting more popular to define a species by using rRNA sequence information. We provide inclusive service of PCR, sequencing and assemble. 1,500bp or longer sequence is guarantee for domain of bacteria.

Please send in an inquiry to us for more information.

Primer Walking:

We provide service to read 2~15kb sequence with PCR product or plasmid DNA that cannot be read fully by single primer extension sequencing. Once performing end sequencing with designated primer by customer, we design internal primers with reference to end sequence data

Standard Custom Oligo Synthesis

We provide reliable high quality standard custom oligo synthesis with guaranteed QC check with MALDI-TOF analysis.

Purification grade available:

1. Bio-RP :
   Most oligos sold are merely desalted. The process of desalting only partially purifies the oligo and leaves behind many impurities. Bio-RP purification removes all contaminants, resulting in an oligos that are near HPLC purity. The advantage is that our product contains only quality oligos without impurities that can inhibit PCR reactions, and potentially disrupt qPCR reaction.
2. PAGE Purified.
3. HPLC Purified.

Long Oligos

We provide synthesis of long oligonucleotides from 130-200 bases. Similar to standard oligos, long oligos are QC tested with MALDI-TOF analysis. Long oligos are available in Bio-RP purification or PAGE purification.

Please send in an inquiry to us for more information.

Modified Oligos and Dual Labelled Probes

We provide reliable high quality modified oligo synthesis with guaranteed QC.
Please send in an inquiry to us for more information.

Available modifications are listed as below:

3’ Modification

5' Modification

Internal Modification

Dual-labeled Probe Combination List

siRNA Synthesis (Pre-designed and Custom)

We provide siRNA Library with over 132,000 predesigned siRNA's from Human, Mouse and Rat, with an 80% siRNA knockdown guarantee. Customers can search the predesigned siRNA databases by Gene ID, Symbol, Synonyms, Description and/or Accession Number by using the search tool provided in the link below.

Genome-wide Pre-designed siRNA Search Tool

Other than pre-designed siRNA, we also provide you custom design siRNA synthesis according to your specs. All custom siRNAs are synthesized in clean room facility and then purified free of charge utilizing Bio-RP purification system. For higher purity, HPLC purification is available at an additional charge. Each siRNA is quality controlled by MALDI-TOF mass spectrometry to guarantee highest quality and analyzed by PAGE to confirm its duplex structure.

Please send in an inquiry to us for more information.

Gene Synthesis

We provide reliable 100% sequence guarantee gene synthesis service. Every synthesized gene will go through DNA sequencing to confirm 100% correct sequence. In addition, codon optimization will be provided for free of charge to enhance protein expression and function.
