Prior consultation with MRC required to prepare a quote.

Life Technologies Proton (Contact: Bill Taylor)

Application Capabilities Advantages Disadvantages Recommendations
Next generation sequencing; genetic variation and discovery RNA-seq; ChIP seq; miRNA seq; whole genome seq;
exome sequencing; 1-96 bar-coded samples for DNA and 1-48 bar-coded samples for RNA; scalable coverage
De novo sequencing; differential gene expression and detection of splicing variants; SNP detection Low abundant transcripts will require deeper coverage for detection; for RNA-seq, must have a reference library; fewer downstream workflows available than for Illumina NGS data Arrange for bioinformatics consultation before run. Prior consultation with MRC required to prepare a quote.

Molecular Resource Center External Sanger Sequencing Submission Policy Change

Samples submitted at the MRC for Sanger sequencing by Azenta (formerly GeneWiz) must be logged into the iLab portal by the laboratory personnel submitting the samples, in addition to completion of the external submission form on the Azenta portal. Both the iLab and Azenta paperwork must be downloaded, printed and submitted along with your samples for sequencing, or they will not be sent out.
