Woburn, MA — Serving labs nationwide

NGS library preparation, dialed to your needs.

A scientist-led NGS library preparation service. You decide how much of the protocol is fixed and how much is yours to shape — from validated standard workflows to fully custom method development. The scientist who scopes your project is the one who runs it at the bench.

How we work

You hold the dial

Defined
Custom
Most projects land somewhere between

Most providers hand you a fixed menu. We hand you a control. Every project sits somewhere on a single spectrum — defined to custom — and gets scoped from there. If you're not sure where yours fits, that's a conversation, not a guess.

Defined workflows

Run it to a known spec

Validated, predetermined protocols with predictable scope. The right choice for routine WGS, RNA-seq, or methylation done correctly and quickly — no one reinventing a workflow that already works.

Good fit for Standard sample types, production-scale batches, and projects where speed and predictability matter most.
Custom & method development

Every parameter on the table

Input type and mass, fragmentation, amplification, cleanups, normalization, QC depth — all open. The prep itself becomes part of the experiment, designed and documented with you.

Good fit for Difficult or precious samples, FFPE and degraded material, cfDNA, titration and optimization studies, and designs the standard menu can't accommodate.
Workflows

Three core capabilities

Each can be run anywhere on the dial. Every workflow starts with a real conversation before your samples ship, and gives you direct access to the scientist doing the work.

Genome

Whole Genome Sequencing

PCR-free and amplified library preparation across a wide range of DNA inputs and quality levels — including samples other providers flag as insufficient or risky.

Flexible across Germline and somatic studies, low-pass and deep coverage, low-input and degraded DNA, input titrations.
Transcriptome

RNA Sequencing

Total RNA-seq and mRNA-seq. We work out the right approach with you before anything ships — ribosomal depletion versus poly-A enrichment, handling for degraded or low-input material, the biological question driving the design.

Flexible across FFPE and degraded RNA, low-input samples, cell lines, blood and tissue, custom depletion strategies.
Epigenome

Methylation Profiling

TAPS+ chemistry — simultaneous detection of 5-methylcytosine and genetic variants from a single library. Non-destructive conversion preserves four-base complexity for superior alignment, higher CpG coverage, and fewer false positives than bisulfite-based approaches.

Flexible across Multiple input types and sequencing platforms. If you're considering methylation work, tell us about your samples and we'll confirm fit.
What you get

Every project follows the same standard regardless of size or where it sits on the dial.

01

Consultation & workflow design

We align on your goals, review your sample types and sequencing requirements, and identify risk areas before anything moves.

02

Preflight sample assessment

Every sample is QC'd on arrival. Concentration, quality metrics, assumptions, and flags — documented before we touch a reagent.

03

Library preparation

Prepared by an experienced scientist using protocols set to your point on the dial — focused, attentive execution.

04

Go / no-go checkpoint

Before committing sequencing dollars, you see every library metric. We review together and make an explicit decision — no surprises downstream.

05

Sequencing coordination

We pool, QC, and deliver your libraries to our local sequencing partners. One invoice, one point of contact.

06

Structured project summary

A single report pulling together every stage of the project — preflight, library QC, pooling, and sequencing hand-off — into one organized document you can keep and share.

Tell us about your project

We scope each project individually. The more you can tell us up front, the more useful our first response will be — if you're not sure about something, leave it blank.

Typical response time: one business day.

Freeform is fine. The more context, the better our first response.
Your submission is confidential. We respond to every inquiry personally, typically within one business day.

About

Built at the bench

Anneal Bio was founded by an NGS scientist with twelve years of hands-on experience across the Cambridge and Greater Boston biotech corridor — including Labcorp and Exact Sciences. The background spans library preparation, high-throughput automation, workflow validation, and quality control across development, production, and clinical-adjacent environments. The idea behind Anneal Bio is simple: give a lab the kind of NGS specialist it would hire if it had the headcount — without the headcount.
