TIP
For Intact Mass Analysis experiments, you can create a mass-only or formula-only oligonucleotide sequence.
Mass-only or formula-only sequences are useful when you want the application to identify components (such as impurities) with a known mass or formula in an Intact Mass Analysis experiment.
Procedure
- On the BioPharma Finder Home page, in the Experiment Types pane, select the Sequence Manager link.
- The Sequence Manager opens.
- On the right side of the Sequence Manager, select the New Oligonucleotide button.
- The Oligonucleotide Sequence Editor opens.
- On the left side of the Oligonucleotide Sequence Editor, in the Sequence Information pane > Target Oligonucleotide area, enter the following information:
- Name: Type the name of the oligonucleotide sequence.
- Description: (Optional) Type a description for the oligonucleotide sequence.
- Category: Select the category for the oligonucleotide sequence from the dropdown menu.
- On the right side of the Oligonucleotide Sequence Editor, expand the Manual Input Sequence pane and then add one chain in the oligonucleotide sequence at a time as follows:
- Type the name of the chain in the Chain Name box.
- Type or paste the new chain sequence into the editable box.
- Select the Apply button.
TIP
Chain names can contain up to 250 alphanumeric characters.
NOTE
You can input oligonucleotide chains using either single-base (ATCGA) or triplet (Ad-pTd-pCd-pAd) notation, using uppercase for bases.
Both single-base and triplet formats are case-sensitive.
TIP
You can copy and paste the sequence chain from a FASTA file using Notepad or another text editing tool.
NOTE
A FASTA file might contain comment lines that begin with a greater-than sign (>), similar to the chain name line.
When you copy a chain sequence, do not include these additional comment lines. The application interprets comment lines as sequence building blocks.
- If the entered chain contains invalid oligo building blocks or an invalid format, an error message appears.
- The Oligo Sequence Map on the left side of the page updates and displays the added chain.
- The name of the chain appears above the chain sequence, indicated by a greater-than sign (>) to distinguish each chain.
- Additionally, the read-only information fields (Monoisotopic Mass, Average Mass, and Formula) in the Sequence Information pane > Target Oligonucleotide area update to reflect the properties of the entire protein.
- In the Sequence Information pane > Chain area, you can view the Monoisotopic Mass and Average Mass properties for an individual chain by selecting the chain number from the dropdown menu.
- Repeat the previous step to add additional chains as needed.
- Save the oligonucleotide sequence.
- The application adds the saved sequence to the Sequence Manager table.
