Bulk online order form

Using our bulk online order form you can order easily a large number of oligonucleotides that differ in their name and sequence but are otherwise identical in their specifications. If you intend to order multiple oligos that differ in other specifications than their name and sequence please use our standard online ordering form.
You can enter the oligo names and sequences in the textbox below, or you can import the respective data from either an Excel or a text file. Below you find a description how the data has to be formatted for bulk import. NEW: You now can also enter oligonucleotide data directly into the textbox below from Excel via cut-and-paste !

About importing oligonucleotide data from an Excel file   Display/Hide help text

The biomers.net bulk import function can read Excel files in all formats used from Excel 97 onwards both from the Windows and Macintosh versions of Excel up to Excel 2010 and Excel 2008 for the Macintosh (file extensions .xls and .xlsx).

The oligonucleotide data must be formatted as follows:
  • No header row. The oligo data has to start in row 1.
  • For each oligo there has to be an oligo name in column A and the oligo's sequence in column B. Any additional data in other columns will be ignored by the import function, but will not interfere with the import process in any way and does not need to be removed before importing the data.
  • As the import function regards the first empty line it encounters as the end of the data to import, the oligonucleotide data must not contain empty rows followed by data that is supposed to be imported.

About importing oligonucleotide data from a CSV text file or by pasting in the field below   Display/Hide help text

Files in the so-called CSV format are ordinary text files that contain data in a certain format: Each line contains one oligonucleotide. Oligo name and sequence are separated by a semicolon (;) or a TAB. Blanks and empty lines will be removed on import. Should your input data have an incorrect number of separators or should your DNA sequences contain illegal characters, the system will warn you on import and you will have a chance to correct the problem.

Below an example of the required input data:

Oligo 1;agtgtgtatgctagctagtgtgtagctagctgatcgatgctagctagct
Oligo 2;tggtacgtagctagcgatgctagctagctgatcgatgctagctagtcgatgc
Oligo n;tgtagcgatgtagctagtcgatcgtagctagtcagtgtagctgt

You can also paste CSV-formatted data in the text box below instead of importing it from a file or you can cut-and-paste the oligonucleotide data from an Excel sheet. Excel will automatically insert TAB characters as column separators in this case.

CSV-formatted files can be exported by many programs. E.g. you can easily create a csv file you can import without further editing if you save an Excel worksheet using the CSV format that does only contain the oligos' names in the first and the oligos' sequences in the second column. Please mind: The import only supports characters that are part of the ASCII character set. Symbols and special characters (e.g. greek letters) are either replaced on import with respective letters and ASCII special characters or are dropped entirely. You should remove all non-ASCII characters before importing. Case of oligonames is preserved. All sequence characters are converted to lower case.

Please do not use any brackets or other special characters in oligoname or sequence.

Oligonucleotides are

Valid oligonucleotide lengths for DNA: 2 to 140 bases.

Wobbles: M=A+C R=A+G W=A+T S=G+C Y=C+T V=A+G+C H=A+C+T D=A+G+T B=G+T+C N=A+G+C+T K=G+T
PTOs are specified by entering an * at the desired position inside the oligonucleotide sequence.
RNA: Please enter desoxy bases as internal modifications.
