Frequently asked questions
What is a Certificate of Analysis (COA) in Peptides ?
A Certificate of Analysis (COA) is a laboratory document containing analytical results for a specific product batch or lot. It identifies the material tested, the batch reference, testing methods and the results obtained from the analysis. For research peptides, a COA may include information such as peptide identity, amount and purity, depending on the tests performed.
Why is a certificate of Analysis important ?
A COA provides documented analytical information about a specific batch rather than relying solely on a product specification or supplier declaration. It allows the reported testing method and results to be reviewed and provides traceability between the laboratory report and the batch tested.
What does third-party laboratory testing mean for TB-500 ?
Third-party laboratory testing means the TB-500 sample was analysed by an external laboratory rather than relying solely on internal testing. In this case, the sample was submitted to Janoshik for independent analytical testing, with the original laboratory report provided alongside the results.
Does this TB-500 COA apply to every batch ?
No. A Certificate of Analysis is batch-specific. The results shown on this page relate to the particular TB-500 sample and batch identified on the certificate. A different batch requires its own analytical documentation if it has been independently tested.
How can I verify this TB-500 Certificate of Analysis?
The Janoshik report contains identifying information that can be used to verify the laboratory record through Janoshik’s verification system. The task number and unique verification key associated with the test can be used to check the corresponding report. Janoshik provides a dedicated online verification system for its reports.
How is TB-500 tested?
The TB-500 sample was analysed by Janoshik using High-Performance Liquid Chromatography (HPLC). The analysis assesses the identity, measured amount and peptide purity of the submitted sample.
What is HPLC testing for TB-500 ?
HPLC, or High-Performance Liquid Chromatography, is an analytical technique used to separate and analyse components within a sample. For peptide testing, the resulting chromatographic profile can be used to assess the target peptide and determine its reported purity and amount.
What does TB-500 peptide purity mean?
The reported peptide purity represents the proportion of the analysed material identified as the target TB-500 peptide using the laboratory’s analytical method. It is reported as a percentage and relates specifically to the sample submitted for testing.
What does the TB-500 amount result mean?
The amount result reports the quantity of TB-500 detected in the submitted vial, expressed in milligrams. This is a measurement of the material analysed by the laboratory and is separate from the peptide purity percentage.
🧪 About This Test (expanded)
The submitted TB-500 sample was independently analysed by Janoshik using HPLC (High-Performance Liquid Chromatography). The analysis is designed to assess the identity, measured amount and peptide purity of the submitted sample, while also distinguishing the full TB4/TB-500 peptide from relevant peptide fragments.
Testing Method
HPLC (High-Performance Liquid Chromatography) is an analytical laboratory technique used to separate and analyse components within a sample. The resulting chromatographic profile is used as part of the analytical assessment of the target peptide and other detectable components.
For TB-500, Janoshik’s published analysis specifically examines whether the full 43-amino-acid TB4 peptide is present or whether a relevant fragment has been identified. The laboratory distinguishes these findings on the resulting report.
For a lyophilised TB-500 sample, the standard result format reports the measured amount in milligrams per vial together with peptide purity.
What Is Analysed?
The analysis assesses three principal characteristics of the submitted sample:
Identity
The analysis determines whether the submitted material corresponds to the specified TB-500/TB4 peptide and distinguishes the full peptide from relevant fragments.
Amount
The quantity of the identified target peptide is measured and reported in milligrams per vial for lyophilised samples.
Peptide Purity
The HPLC analysis is used to determine the reported proportion of the analysed material represented by the target peptide, expressed as a percentage.
TB-500 and Peptide Fragments
Janoshik’s TB4/TB-500 analysis is specifically designed to distinguish between the full-length peptide and relevant fragments. Their published specification identifies the full 43-amino-acid TB4 sequence, as well as the 17–23 fragment, among the target compounds covered by the analysis.
This distinction is important when interpreting a TB-500 laboratory report because the identity of the material is assessed rather than simply assuming that a sample labelled “TB-500” contains the intended peptide.
The analysis relates specifically to the sample submitted to Janoshik and the corresponding batch identified on this Certificate of Analysis.
The original Janoshik laboratory report is provided on this page so that the reported analytical information can be reviewed directly.
