FTS, Thymuline · CAS 78922-62-0

Thymulin 10mg is the Pepta Labs listing for synthetic thymulin (FTS), sold as a laboratory reference material. Each sealed glass vial holds a supplier-stated 10 mg of lyophilized powder of the metal-free nonapeptide, not the zinc complex, typically as an acetate or trifluoroacetate salt. 10 mg is the only thymulin size Pepta Labs lists. The HPLC purity and mass spectrometry report for the sampled production run can be requested on this page or by email to support@peptalabs.com, before ordering if you want to see it first.

Thymulin 10mg: $31.43 per vial ($3.14 per mg of the supplier-stated 10 mg). Ships to US addresses only. Thymulin 10mg is a lyophilized research peptide supplied as 10mg of dry powder per sealed vial. CAS 78922-62-0; molecular formula C33H54N12O15; molecular weight 858.86 Da. Purity is reported as 99% by reversed-phase HPLC and identity is confirmed by mass spectrometry; the analytical report is available by email. Supplied for laboratory research use only.

Chemical identity

What Thymulin is

Thymulin (FTS) is a synthetic linear nonapeptide with an N-terminal pyroglutamate residue and a free C-terminal acid: pGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH (one-letter pE-AKSQGGSN-OH). The molecular formula of the metal-free peptide is C33H54N12O15, molecular weight 858.86 g/mol (monoisotopic mass 858.39 Da), CAS Registry Number 78922-62-0 and PubChem CID 71300623. The naturally occurring form is a zinc(II) complex of this nonapeptide; the material sold as thymulin is the metal-free peptide, which is a distinct chemical entity from the zinc complex. The pyroglutamate (5-oxoproline) N-terminus is a cyclized glutamine residue and carries no free amino group. Pepta Labs lists thymulin as 10 mg of lyophilized powder per sealed glass vial, typically as an acetate or trifluoroacetate salt, with reported RP-HPLC purity (99.0% on the current listing) and identity confirmed by mass spectrometry. Store at 2-8 C short term or -20 C long term, protected from moisture. For laboratory research use only.

Also known as: FTS, Thymuline
Structural class: synthetic linear nonapeptide with N-terminal pyroglutamate (metal-free form)
Residues: 9 amino acids

Questions

Thymulin 10mg — common questions

Where can I buy thymulin, and what sizes are sold?

On this page. Thymulin is listed in one size only: a 10 mg sealed vial of lyophilized powder. No other thymulin size is listed.

What exactly is in a Thymulin 10mg vial?

A supplier-stated 10 mg of freeze-dried thymulin powder in a sealed glass vial, as the metal-free peptide salt. The vial carries no lot number, vial fill-quantity testing is not claimed, and net peptide content is not reported per listing.

Is thymulin supplied as a TFA or acetate salt?

Thymulin is typically supplied as an acetate or trifluoroacetate (TFA) salt. Net peptide content is not reported per listing. The Learn guide TFA vs Acetate Peptide Salts explains how the salt form appears on an analytical report.

How do I get the thymulin HPLC and mass spec report?

Request it on this page or email support@peptalabs.com with the compound name, before ordering if you want. The report covers the sampled production run: purity is RP-HPLC area-%, and identity is by mass spectrometry; the metal-free peptide has a monoisotopic mass of 858.39 Da. The Learn guide How to Read and Verify a Peptide Certificate of Analysis walks through each field.

Are FTS and thymuline the same compound as thymulin?

Yes. FTS and thymuline are other names for the same nonapeptide, and this listing is its synthetic metal-free form. The Learn guide Peptide Sequence Notation explains how its pGlu-prefixed sequence is written.

How should sealed thymulin powder be stored?

Keep the sealed vial of dry powder at 2-8 C on arrival or at -20 C for long-term storage, protected from light and moisture. It ships as dry powder at ambient temperature. The Learn guide Storage Temperature and Handling of Lyophilized Research Peptides covers the details.

What does Thymulin 10mg cost?

Thymulin 10mg starts at $31.43 per vial. 3-vial packs are 10% off and 5-vial packs are 15% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. Thymulin 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

What does pGlu at the start of the thymulin sequence mean?

pGlu (pyroglutamate, 5-oxoproline) is a glutamine residue whose side chain has cyclized onto the N-terminal amine, forming a lactam. The peptide therefore has no free N-terminal amino group, which is reflected in its formula C33H54N12O15 and mass 858.86 g/mol.

Is thymulin sold as the zinc complex?

No. The listed compound is the metal-free nonapeptide (CAS 78922-62-0). The zinc(II)-bound form is a separate entity with a different mass.

Is thymulin the same as thymosin alpha-1?

No. Thymulin is a 9-residue peptide of 858.86 g/mol (CAS 78922-62-0), whereas thymosin alpha-1 is a 28-residue acetylated peptide of 3108.3 g/mol (CAS 62304-98-7). The two share the thym- name root only.
