Product
What is Thymosin Alpha 1?
Thymosin Alpha 1 is a synthetic 28-residue acetylated peptide. Thymosin Alpha Labs supplies it as a white lyophilized powder in 5 mg vials, with an independent certificate of analysis for every lot.
What is Thymosin Alpha 1 research material?
Thymosin Alpha 1 research material is Thymosin Alpha 1 supplied for laboratory research, sold by lot, with each lot's identity, purity and net content documented by an independent laboratory in a published certificate of analysis.
What is the molecular formula and weight of Thymosin Alpha 1?
The molecular formula is C129H215N33O55 and the average molecular weight is 3108.32 g/mol. The peptide has 28 residues.
How should Thymosin Alpha 1 be stored?
Store sealed, dry and protected from light at the temperature stated on the vial label. Allow a cold vial to reach room temperature before opening.
Where is the current Thymosin Alpha 1 certificate?
The current batch is with the laboratory. Its certificate will be published on this site when the report is issued.
What is the sequence of thymosin α1?
Ac-SDAAVDTSSEITTKDLKEKKEVVEEAEN: 28 residues with an acetylated N-terminus, C129H215N33O55, 3108.32 g/mol.
Testing and quality
How is Thymosin Alpha 1 analyzed?
Thymosin Alpha 1 is analyzed with complementary methods: HPLC-UV for purity, LC-MS for identity, a quantitative measurement for net content, and, where listed, LAL endotoxin and PCR microbial testing. Results are published per lot at thymosinalpha.bio/coa/.
Who tests Thymosin Alpha 1?
Every lot is tested by Freedom Diagnostics, an independent third-party analytical laboratory. Thymosin Alpha Labs does not test its own material for published certificates.
What purity does Thymosin Alpha 1 test at?
Purity is reported per lot by HPLC-UV.
How is the identity of Thymosin Alpha 1 confirmed?
By liquid chromatography–mass spectrometry (LC-MS), performed by Freedom Diagnostics on every lot. LC-MS separates the sample and measures the mass of the main component, confirming it has the molecular weight expected for the compound.
Is Thymosin Alpha 1 tested for endotoxin?
Endotoxin and microbial testing are reported per lot. Every lot page in the COA archive states whether those tests were performed.
What is HPLC testing, and what does the purity percentage mean?
HPLC (high-performance liquid chromatography) separates a sample's components so each appears as a peak. The purity percentage is the main peak's share of all UV-detected peak area. It does not confirm identity (the separate LC-MS test does) or measure the amount of peptide in the vial (net content does).
Certificates of analysis
What is a Thymosin Alpha 1 COA?
A Thymosin Alpha 1 certificate of analysis is the testing laboratory's report for one lot: the lot number, test dates, methods and results for purity, identity and net content. Thymosin Alpha Labs publishes every lot's COA as a readable page at thymosinalpha.bio/coa/.
Where can I find the COA for my vial?
Find the lot number printed on your vial label and enter it at thymosinalpha.bio/verify/, or open that lot in the COA archive at thymosinalpha.bio/coa/.
How do I confirm a COA with the laboratory?
Scan the Freedom Diagnostics QR code printed on the certificate, then search for klow.bio under the Company tab to view the laboratory record.
Why is the measured net content different from the vial size?
Net content is the laboratory's measurement of peptide in the tested vial.
Buying Thymosin Alpha 1
Where can I buy Thymosin Alpha 1?
