SIGNALYN BIO / THIRD-PARTY TEST REPORT
SS-31 Third-Party Test Report — Batch 2S202639
Batch-specific third-party laboratory testing for Signalyn Bio SS-31, including HPLC purity, LC-MS identity evidence, endotoxin testing, and reported content data.
REPORTED RESULTS
Batch Testing Summary
The values below are reported for the submitted SS-31 sample from batch 2S202639. Each result addresses a different analytical question and should be interpreted within the scope of the stated method.
99.84%
Reported HPLC Purity
Conforms
LC-MS Identity Evidence
0.335 EU/mg
Endotoxin — PASS
11.75 mg
Reported Net Content
Important: HPLC purity, molecular identity, endotoxin, and reported content are separate analytical measurements. A single purity value should not be interpreted as a complete quality assessment.
ANALYTICAL REVIEW
What the Report Shows
HPLC Purity
The report lists a purity result of 99.84%. The detailed chromatographic output shows a principal peak area of 99.8477% at 220 nm under the stated LCMS method.
LC-MS Identity Evidence
The report states that the mass spectrum conforms to the expected protonated ion forms for SS-31. This supports molecular identity assessment and is distinct from chromatographic purity.
Endotoxin
Endotoxin was reported at 0.335 EU/mg against a stated specification of <1 EU/mg, and the report marks the result as PASS.
Reported Net Content
The report states a net content value of 11.75 mg. This result should be interpreted according to the laboratory’s stated method and reporting basis rather than treated as equivalent to HPLC purity.
TESTING CLASSIFICATION
Third-Party Partner Laboratory Testing
This report represents testing performed through a third-party partner laboratory and compiled as part of Signalyn Bio’s batch quality documentation. It is distinct from an independently commissioned blind test such as a Janoshik submission.
The report states that neither Signalyn Bio nor the partner testing laboratory holds CMA/CNAS accreditation. It should not be used for regulatory submissions, litigation evidence, or other purposes requiring legally accredited documentation.
