Ion Proton™ System - FAQs

W1 pHが設定されている上限/下限値から外れている可能性、または、W1ボトル内の溶液量が少ない可能性があります。半導体チップ上での測定に失敗した可能性がありますので、W1ボトル内の溶液量を確認し、画面内にあるStartボタンを押し、再測定を行って下さい。再度測定してPassした場合は、そのままランを行います。
再度エラーが出る場合は、
1) W1のpH.　
2) W1の残量.
3) エラーメッセージ.
をご確認のうえ、テクニカルサポート(0120-477-392)までご連絡下さい。

The pH of W1 may be out of range or the volume of W1 may be too small or there may have been a minor problem during measurement. Check the amount of W1, press the 'Start' button on the screen, and restart the measurement. If it passes, continue to start the run. If an error appears again, please note the pH of W1, the amount of W1, as well as the error message, and contact Technical Support.br/>
Please note that passing pH values for the reagents may vary depending on the sequencing kit used, but the instrument will automatically determine the correct pH range depending on the sequencing kit selected during initialization. If you are performing the reagent check outside of the initialization, please contact Technical Support for guidance.

Ion Torrent semiconductor sequencing is the first post-light sequencing technology. Ion sequencing works by taking advantage of the natural release of hydrogen ions during nucleotide incorporation by DNA polymerase. By directly coupling chemical and digital information, Ion Torrent platforms provide a fast, simple, and scalable sequencing solution to meet your lab's needs.

The GGCCAAGGCG sequence is part of the RNA library adapter sequence. This sequence can be automatically trimmed by the software by selecting the “RNA_Barcode_None” option under the Barcodes menu. The run can be reanalyzed with the correct barcode settings to trim the adapter sequence. In the future, the “RNA_Barcode_None” option should be selected in the run plan or selected on the instrument prior to starting the sequencing run.

Primary analysis and secondary analysis of the data is performed by the Ion Torrent Server. Depending on the application, there may be tertiary analysis plugins that can be installed on the Torrent Server. For other applications, such as RNA-Seq, we recommend using third-party software.

Open the chip clamp and check for any leaks. If you see solution leaking, please remove the chip and clear the solution with a Kimwipe tissue. DO NOT wipe or scrub, as the socket could be damaged. Clean the socket by gently touching it with a damp Kimwipe tissue. Make sure the socket is dry and replace the chip. Press the “Calibration” button to recalibrate the chip. If it fails again, change the chip to a different one. Also, if you are using an Ion 316 chip v2 on a v3.4 or older instrument, the instrument will not recognize the chip.

The Ion PGM System and Torrent Server may not be connected. Please shut down the system and server and reboot them. The server may enter a system check after the reboot, which will take 3-4 hours. If you have a monitor and keyboard connected directly to the Torren Server, you can avoid the system check by pressing “c” on the keyboard.

If there is a reason you cannot reboot the system, you can run the Ion PGM System without connection to the server. The runs will be saved inside the system. For 200 bp sequencing, here is the number of runs that may be saved for these chip types:

Ion Torrent Ion 314 chip: 40 runs

Ion Torrent Ion 316 chip: 6 runs

Ion Torrent Ion 318 chip: 5 runs

The data will automatically transfer to the server after connection.

The pH of the nucleotides may be out of range or there may have been a minor problem during measurement. Press the “Start” button and restart the measurement. If it passes, continue to start the run. If an error appears again, please note the pH of R1, R2, R3, and R4, as well as the error message, and contact Technical Support.

Please note that passing pH values for the reagents may vary depending on the sequencing kit used, but the instrument will automatically determine the correct pH range depending on the sequencing kit selected during initialization. If you are performing the reagent check outside of the initialization, please contact Technical Support for guidance.
