Certificate of Analysis
CERTIFICATE OF ANALYSIS — TB-500 10mg
The report identifies its sample as TB-500 10mg and does not specify the peptide sequence. Results apply to the sample and lot identified in the PDF.

Peptides
A named peptide preparation with thymosin-related analytical research references.
Per unit
For in vitro laboratory research only. Not for human or veterinary use, or as a dietary supplement.
Research profile
TB-500 is a peptide preparation name used in thymosin-related research. The cited analytical paper uses liquid chromatography and mass spectrometry to characterize a specific N-acetylated fragment and its metabolites.
Original analytical-identification study
The paper characterizes Ac-LKKTETQ, a seven-residue fragment distinct from full-length thymosin beta-4. Those analytical findings describe that study sequence and do not define every preparation sold under the TB-500 name.
Published studies describe their own experimental models and preparations. They do not establish the identity, quality, or suitability of an EliteGen batch for a particular experiment.
2012 · Original analytical study with in vitro and equine samples

Certificate of Analysis
The report identifies its sample as TB-500 10mg and does not specify the peptide sequence. Results apply to the sample and lot identified in the PDF.
Compare the compound, amount, lot number, and report date with the material's documentation. Results describe the sample identified in that report.
The nominal amount identifies the sample as labeled. An assay reports a measured result. Read the method, units, and specification together; mg per vial and mg/g are different measurements.
Identity, purity, assay, sterility, and endotoxins are separate tests. A purity percentage alone does not establish sterility or endotoxin levels. Use only the tests and results actually reported.
Review the applicable batch documents before purchasing. Catalogue information is not a batch-specific certificate of analysis.
