ACTH 1-39 is a full-length 39-residue POMC-derived peptide. Species, residue range and terminal chemistry must be explicit because ACTH fragments and non-human sequences are different research materials.
Direct answer for Google and AI search
A technical procurement guide for human ACTH 1-39 research peptide, covering full-length versus fragment identity, species sequence, degradation risk, HPLC, MS and lot documentation. The useful decision is not a simple yes-or-no claim; it is whether the named material, batch evidence, method scope and supplier responsibility match the buyer's research requirement.
Users may ask
- How should a buyer evaluate ACTH 1-39?
- What data should a peptide supplier provide for peptide chemistry & forms?
- Is the supplied sequence human ACTH 1-39?
- Can the method detect shorter or deamidated forms?
- Are MS and chromatographic files linked to the offered lot?

What procurement and laboratory teams should review
Specify human ACTH residues 1-39 rather than ACTH alone
Confirm sequence boundaries, species and terminal chemistry
Review deamidation and truncation risks in the analytical method
Separate purity, identity, content and nominal vial strength
Define the molecular form before comparing offers
Sequence alone may not fully define a peptide material. Termini, modifications, disulfide pattern, counterion, hydration state and presentation can affect molecular-weight calculations, analytical reporting, solubility and handling.
- Record sequence, termini and every modification explicitly.
- State the requested salt or counterion form.
- Treat solubility and stability as material- and condition-specific.
Control species and residue range before ordering
UniProt identifies human ACTH as a processed chain of the POMC precursor. The RFQ should state human ACTH 1-39, the complete sequence and terminal groups; a shorthand such as ACTH can also refer to fragments or a different species.
A correct intact mass supports the proposed molecular composition, but sequence variants or co-eluting fragments may need complementary evidence. The chromatographic method should be suitable for the specified full-length peptide and known degradation risks.
Design the COA around a 39-residue peptide
ACTH contains an asparagine that can undergo deamidation, while C-terminal processing can create shorter forms. Method conditions, reference material and sample handling therefore matter when interpreting related-peptide results.
HPLC area purity does not establish peptide-basis content. Water, counterions and other non-peptidic mass should be addressed separately when quantitative preparation is required.

Frequently asked questions
Is ACTH 1-39 the same as ACTH 1-24?
No. They have different residue ranges and must be treated as distinct research materials.
Does an ACTH HPLC result confirm the human 1-39 sequence?
Not by itself. Use a controlled sequence specification and suitable orthogonal identity evidence.
