Oligo Pool Guide - Design, Synthesis, QC & Vendors
An oligo pool is a mixed library of many DNA oligonucleotides synthesized together for high-throughput applications such as CRISPR screens, custom NGS panels, gene assembly, and mutagenesis. Start here to understand the concept, then move into design rules, synthesis choices, QC interpretation, vendor short-listing, ordering checks, and application-specific guides.
Use this guide for oligo pool design, synthesis, QC, vendor, and ordering decisions. Move to vendor pages after the pool requirements, QC expectations, and file format are clear.
Oligo Pool at a Glance
Use these answers before you choose a synthesis method, run QC, or compare vendor quotes.
What is an oligo pool?
An oligo pool is a mixed library of many distinct DNA oligonucleotides synthesized together in one pooled format instead of ordered as separate tubes.
What does oligo pool design include?
Design covers sequence length, GC range, homopolymers, secondary-structure risk, adapter or primer handles, application coverage, and pool-size planning.
What should be checked before synthesis?
Check batch sequence QC, dropout risk, representation needs, synthesis method fit, file format, naming rules, and vendor-specific feasibility limits.
Where do vendor decisions fit?
Vendor review should come after the design and QC constraints are clear, so quotes can be compared using the same pool size, length tier, QC scope, and delivery assumptions.
Which pages should I open after this overview?
Use design rules for sequence constraints, quality metrics for QC interpretation, vendor comparison for ordering assumptions, and the ordering guide for final file and submission checks.
Use this page as the checkpoint before vendor review
Move from the oligo pool overview into submission checks without creating an account: validate the design, review synthesis risks, convert the order file, then confirm the latest vendor-specific limits before submission.
Order-ready checklist
This checklist is a planning guardrail, not a replacement for the vendor portal's current terms, eligibility rules, or product-specific feasibility review.
Oligo Pool Design & Ordering
Design an Oligo Pool Before Ordering
Move from application choice to order-ready sequences with a five-step pre-order checklist.
Check Oligo Pool Design Rules
Check length limits, GC content, homopolymer runs, and other sequence rules before ordering.
Order an Oligo Pool
Prepare file formats, naming rules, pool-size checks, and a submission checklist before ordering.
Estimate Oligo Pool Cost
Estimate pool cost by application, length tier, QC package, and vendor add-ons before requesting quotes.
Oligo Pool Applications
Design a CRISPR sgRNA Oligo Pool
Size genome-wide or focused sgRNA libraries, run pre-order QC, and choose the right vendor before ordering.
Assemble Synthetic Genes from an Oligo Pool
Plan fragment lengths, overlap design, and assembly steps before ordering a gene synthesis pool.
Design a Custom NGS Panel Oligo Pool
Plan hybrid capture or amplicon probes with panel sizing, tiling, and QC checks before ordering.
Design a Mutagenesis Oligo Pool
Plan DMS and saturation libraries with explicit variants, balanced coverage, and sequencing-ready QC.
Oligo Pool QC, Vendors & Troubleshooting
Read Oligo Pool QC Metrics
Interpret uniformity, dropout, error rate, Gini, and representation metrics in vendor or NGS QC reports.
Choose Between Array and Column Synthesis
Compare array-based and column-based synthesis before you choose a vendor or synthesis method.
Troubleshoot Oligo Pool Problems
Diagnose dropout, skew, low accuracy, and cloning failures before you reorder.
Compare Oligo Pool Vendors
Normalize vendor quotes by pool size, length tier, QC scope, delivery format, and turnaround assumptions.
Oligo Pool Research & Decision Pages
Use these pages when you need QC ranges, public vendor specs, or final submission checks. The vendor directory is for provider discovery; the vendor comparison page is for pool-specific quote normalization after design constraints are known.
QC Thresholds by Application
QC bands for CRISPR, DMS, MPRA, and gene assembly pools.
QC Request Guide
Decide what QC to request and when to run pre-order screening.
Vendor Specification Notes
Public length, capacity, turnaround, QC wording, and ordering caveats.
Vendor Decision Page
Turn public specs into a shortlist before requesting quotes.
Ordering Checklist
Check file formats, IDs, pool size, and final submission details.
Provider Directory
Discover providers before moving into pool-specific vendor comparison.
