About Prime Labs
Quality, transparency, and support for scientific research.
At Prime Labs, we are committed to supporting laboratory discovery with research-grade lyophilized peptides backed by third-party analytical verification, transparent batch COAs, U.S.-based operations, and a researcher-first approach.
What sets us apart
Standards researchers can review.
Explore the core pillars Prime Labs maintains across peptide synthesis verification, independent batch testing, U.S. fulfillment operations, and laboratory documentation support.
Premium Quality Peptides
Quality starts with the inputs researchers receive. Our lyophilized peptides are synthesized under strict solid-phase protocols and analytically verified to achieve ≥99% purity.
Third-Party Lab Tested
Every production batch undergoes independent analytical verification via Reverse-Phase HPLC and Mass Spectrometry to confirm molecular identity, purity, and absence of contaminants.
U.S.-Based Fulfillment
All research orders are inspected, packed in protective USP Type I borosilicate vials, and dispatched from our U.S. fulfillment center with tracked delivery options.
Dedicated Research Support
Our institutional and researcher support desk assists with batch Certificates of Analysis, chemical specifications, wholesale inquiries, and order tracking.
The Standard of Excellence
Always quality-tested. Verified across 4 analytical dimensions.
At every step, we prioritize reproducibility by conducting rigorous third-party testing focused on four critical laboratory characteristics:
Molecular Identity
Electrospray Ionization Mass Spectrometry (ESI-MS) confirms exact molecular weight and amino acid sequence integrity.
Assay Purity (≥99%)
RP-HPLC chromatograms verify single-peak purity and quantify any synthesis-related peptide impurities.
Sterility & Vacuum
0.22µm membrane filtration prior to lyophilization and nitrogen-purged crimping preserve compound stability.
Endotoxicity (LPS)
LAL endotoxin screening ensures bacterial lipopolysaccharide levels remain strictly below analytical thresholds.
From product to delivery
Our standards in practice.
Quality First
Disciplined laboratory standards and batch-to-batch consistency guide how every reference material is labeled and documented.
Fast U.S. Fulfillment
Verified researcher orders placed before our daily dispatch cutoff (Monday–Friday) are processed for rapid U.S. shipping with full tracking.
Secure Research Packaging
Lyophilized vials are sealed in tamper-evident flip-off caps and protective outer cartons to maintain structural integrity in transit.
Strict RUO Compliance
We enforce 21+ researcher verification and strict FD&C Act Section 503A/503B Research Use Only compliance across every order.
