ExiProgen™ :
Synthetic Biology meets Automation Technology


The field of biology and many commercial industries are directing their attention to synthetic biology to solve increasingly complex questions and problems. Commonly used methods to achieve synthetic biology goals are cumbersome and slow at best. But that’s changed thanks to Bioneer’s ExiProgen™ system! ExiProgen™ is a breakthrough in synthetic biology allowing for the synthesis and purification of one to 16 proteins per run. Simply add DNA, press run and in about 6 hours the system will synthesize and purify up to 16 different proteins. DNA, in the form of plasmid or linear PCR product, is added to the system and Bioneer’s coupled transcription/translation E. coli extract then synthesizes the protein. The crude protein extract is further purified, using His-Tag engineered into the proteins.
The net result is up to 100 ug of >90% pure Protein in about 6 hours.
ExiProgen™ can also purify Nucleic Acids from several sources, making it one of the most versatile systems available.




Features and Benefits

Fully automatic: DNA-in-Protein-out: Pipette 6~10 μg of DNA into the kit and load into ExiProgen for high-purity proteins within 6 hours.
Parallel Process: Synthesize and purify1 to 16 unique proteins simultaneously.
High performance: The system enables synthesis of proteins that are toxic to in vivo expression systems.
High purity and High yield: Each well will yield up to 100 μg protein that is over 90% pure.
Reproducibility: Since you only need to add template DNA to obtain your protein, reproducibility is maximized.

2. Total RNA Extraction from Tissue or cultured mammalian cell
- Sample: 15 ㎎ (Rat liver tissue) or 1 X 106 cells (HeLa)
- Protocol number: 202
- Average yield: 25 ug (Rat liver tissue), 10 ug (HeLa)
- Average RQS: > 9.5

* RQS(RNA quality score): he Caliper RQS is a calculated score that rates the quality of RNA samples. The RQS has been validated to correlate well with Agilent’s RIN (RNA Integrity Number) and follows the same 0-10 scale rating. Results comparing RIN to RQS for the same samples run on both LabChip GX and Agilent’s Bioanalyzer 2100 typically show <10% deviation ( http://www.caliperls.jp/assets/pdf/lcgx/lcgx-AP-402.pdf)


Procedure


Rat total RNA Extracted from tissue


Total RNA from Rat was observed to contain intact rRNA with no evidence of degradation.



Real-Time PCR carried out on Rat Total RNA

Real time RT-PCR was carried out.AccuPower® RocketScrpt™ RT PreMix(K-2101, Bioneer), and AccuPower® DualStar™ qPCR PreMix(K-6110, Bioneer) , and the Exicycler™ 96 Real-Time PCR system (A-2060).



Analysis of total RNA from HeLa cells.

Total RNA was extracted from HeLa cell (1 X 106 cells) and analyzed using the LabChip GX (Caliper Life Science). Each subunit of rRNA is clearly seen with no detectable degradation . In addition, the average yield of Total RNA was 10 ug, and the average RQS was 9.5 or higher.
