For library prep

Nucleic Acid requirements for library preparation

suspension buffer:

Samples may be suspended in different types of buffer, including 10mM Tris, dH2O, or Qiagen EB. We do however prefer when samples are suspended in dH2O. It will allow us to concentrate the samples when necessary without having to worry about concentrating the salts present in other types of buffer. High salt (EDTA) concentration can interfere with the various enzymes that are used during library preparation, especially for PacBio sequencing.

Plates and Tubes:

When submitting one sample, please submit in a 1.5mL Eppendorf tube. Make sure to write the sample number listed on your order sample sheet on the top the tube.

Should you submit more than one sample,  please use polypropylene PCR plates.  Plates should be labeled with the order number and sample number range clearly marked (e.g 4596_S01-S96), and should be sealed firmly with a foil plate seal capable of withstanding -80 C temperatures. We recommend the Thermo Scientific™ Adhesive PCR Foil Plate Seal (Fisher AB-0626). If you have more than one plate please also number the plates (e.g  4596_S01-S96_Plate1,  4596_S97-S192_plate2). For the plates, we recommend the Olympus 96-Well PCR Plate, Semi-Skirted (Genesee Scientific # 27-108).

Any plate submitted must be clear and semi-skirted! We will not accept full-skirted, deep well, round-bottom, or flat-bottom plates!

Samples should be loaded on the plate in columns and not in rows!   Sample 1 should be in well A1, sample 2 in well B1, sample 3 in C1, etc.

Sample Concentration and Volume:

Illumina Sequencing:

All samples undergo quality check (QC) before going into library preparation. Make sure to include enough volume to allow for 5 uL to be used in QC. The inputs listed below should remain after the completion of this QC.
