We offer free consultation. Please contact David Mohr to discuss your project in detail.

At the GRCF High Throughput Sequencing Center, our goal is to provide the research community at Johns Hopkins University with access to ‘next generation’ sequencing platforms. We currently feature three HiSeq 2500 instruments two MiSeq instruments, and a NovaSeq6000.  We do our best to sequence samples in a timely manner, but our primary focus is on generating high quality data.

We offer simple, per lane and per flow cell pricing, along with end to end service for whole exome/custom targeted projects, RNASeq, and whole genome.

NovaSeq6000 v1.5 reagents

Illumina is now offering v1.5 reagents for NovaSeq, which lowers cost for runs

NovaSeq Pricing

NovaSeq Order
NovaSeq runs are fixed, but include additional cycles for dual indexed libraries.

Per lane loading is possible on NovaSeq, but adds $150 in cost per lane.

SP: ~1.6 billion paired reads, ~800 million single readsS1: ~3.2 billion paired reads, ~1.6 billion single readsS2: ~8.2 billion paired reads, ~4.1 billion single readsS4: ~20 billion paired reads, ~10 billion single reads
100 cycle: $3600 100 cycle: $6000 100 cycle: $9300
200 cycle: $4300200 cycle: $7000200 cycle: $11100200 cycle: $15000
300 cycle: $4600300 cycle: $7500300 cycle: $11600300 cycle: $17400
500 cycle: $5800

HiSeq2500 Flowcell Pricing (Rapid Mode)

Per Flowcell Order

Single Read Flowcell: ~300 million readsPaired End Flowcell: ~600 million reads
50 bp: $2000 per flowcell50 bp (x2): $3400 per flowcell
75 bp: $2400 per flowcell75 bp (x2): $4000 per flowcell
100 bp: $2800 per flowcell100 bp (x2): $4400 per flowcell
150 bp: $3600 per flowcell150 bp (x2): $5400 per flowcell

Non-standard read lengths are also available for Per Flowcell orders. Please inquire about pricing.

High Output Runs are available, but you should consider the NovaSeq for high throughput applications, as the cost per base will be cheaper.

Sample Requirements

Completed Libraries: For NovaSeq runs, please submit at least 50ul of your sample at 4nM. Please submit 10μl of your sample at 2nM for HiSeq/MiSeq.  Samples must be pooled.  We will do a QC check via Bioanalyzer to increase the likelihood of quality data, but you should quantitate your sample as accurately as possible.  Nanodrop is not reliable.  qPCR is by far the most accurate, but intercalating dye methods can be used.

Library Prep:  $250/sample.  Please provide us with ~500ng of high molecular weight DNA or total RNA >6.5 for this price.  There are a host of options for lower input/lower quality that may add cost.  Please contact us to discuss sample submission.

Data Yield

Our facility features the HiSeq 2500 platform. We almost exclusively run our instruments in Rapid Run Mode, due to the fast run times and low error rates. Yield is dependent upon several factors:

  • Read Length: the longer the read, the more data.
  • Read Type: paired end reads yield twice the data as single read.
  • Optimal Cluster density: it is imperative to accurately quantitate your library to ensure high data yield. We do our best to QC libraries before sequencing, but we cannot pool samples for you.
  • High Quality Library: libraries that contain a high level of adapter dimers will yield significantly less data, particularly on the NovaSeq6000. Similarly, over amplified libraries can negatively impact yield.
  • Uniform Base composition: while less of an issue than in the past, libraries that have uneven base composition tend to pose problems with the HiSeq analysis software. These issues can be mitigated using several strategies, but the net effect will be lower data yield per lane than a balanced library.

Please see Illumina’s HiSeq 2500 and NovaSeq6000 Specification page for current data yields. While we regularly achieve greater than ‘spec’ yields from the HiSeq2500 and NovaSeq6000, typicially matching yields, it is best to be conservative when planning your experiments.

Data Delivery

Per lane/flowcell sequencing:  Data will be returned in Sanger FASTQ format via our high speed aspera server

End to end services:  alignment files, variant calls, and any intermediate files you wish via aspera server
