Third-Party Analytical Testing of Research-Use-Only (RUO) Peptide Batches

We are seeking a qualified laboratory to conduct third-party analytical testing on multiple RUO (Research-Use-Only) peptide batches. The objective is to independently validate supplier claims and evaluate the structural and functional integrity of each batch under in vitro conditions.

Testing Goals:

• Confirm peptide structural identity and integrity

• Quantify net peptide content and assess purity

• Evaluate potency using in vitro assays

Requested Analytical Methods:

1. Identity Verification

• Techniques such as Mass Spectrometry (MS), HPLC, or peptide mapping to confirm molecular structure

2. Purity and Net Peptide Content

• HPLC or LC-MS to quantify total peptide composition and active content

3. Potency Testing

• ELISA assays or cell-based functional bioassays using target-expressing cell lines

• Functional readouts may include cAMP or calcium flux, reporter gene activity, or downstream signaling assays

• Alternative validated in vitro methods may be proposed

Desired Deliverables:

• Comprehensive report with identity, purity, and potency results

• Potency metrics expressed relative to a reference sample (e.g., % deviation or pass/fail)

• Certificates of Analysis (COAs) for each peptide batch

Additional Information:

Please include details on available assay platforms, estimated turnaround time, sample volume requirements, and pricing. Labs outside the U.S. are welcome to respond.
