16mg/vial

This listing is ARA-290 16mg, the synthetic 11-residue peptide also listed under the name cibinetide, sold by Pepta Labs as a laboratory reference material. Each sealed glass vial holds a supplier-stated 16 mg of lyophilized (freeze-dried) powder; the fill quantity is stated by the supplier, not measured per vial. 16 mg is the only ARA-290 size Pepta Labs lists, so larger quantities are bought as multiple vials. The HPLC purity and mass-spectrometry identity report for the sampled production run is sent by email on request, before you order if you want it: request it on this page or email support@peptalabs.com.

ARA-290 16mg: $75.00 per vial ($4.69 per mg of the supplier-stated 16 mg). Ships to US addresses only. ARA-290 16mg (Cibinetide (ARA-290)) is a lyophilized research peptide supplied as 16mg of dry powder per sealed vial. CAS 1208243-50-8; molecular formula C51H84N16O21; molecular weight 1257.32 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.

Questions

ARA-290 16mg — common questions

Is ARA-290 the same as cibinetide?

Yes. The listing's full name is Cibinetide (ARA-290): ARA-290 and cibinetide are two names for the same 11-residue peptide, listed under CAS 1208243-50-8. Pepta Labs lists it once, as this 16 mg vial.

What size is the ARA-290 vial, and is there a 5mg or 10mg?

One size only: a 16 mg vial. There is no smaller or larger ARA-290 vial on the site. Multi-vial packs of the same 16 mg vial are shown in the price answer on this page.

What exactly is in the ARA-290 16mg vial?

A supplier-stated 16 mg of lyophilized ARA-290 powder in a sealed glass vial, shipped dry. The 16 mg is not a net peptide content figure: a lyophilized synthetic peptide can also carry counter-ion and residual water, and the listing states neither a salt form nor a peptide-only amount. Vials are not lot-numbered.

Where can I buy ARA-290 16mg?

On this page. Pepta Labs lists ARA-290 as one 16 mg vial of lyophilized powder, sold as a laboratory reference material, not for human or animal use. You can get the HPLC/MS report for the sampled production run before you order: request it on this page or email support@peptalabs.com.

How do I get the HPLC and mass spec report for ARA-290?

Request it on this page or email support@peptalabs.com with the compound name; it is sent by email, before you order if you want it. The report covers the sampled production run Pepta Labs sourced, not an individual vial. Purity is RP-HPLC area-%, and identity is by mass spectrometry, where the observed mass is compared with the mass calculated from the listed formula C51H84N16O21 (1257.32 Da is the average molecular weight). The Learn guide on reading a peptide certificate of analysis walks through each field.

How should sealed ARA-290 powder be stored?

Keep the sealed vial at 2-8 C on arrival or at -20 C for long-term storage, away from light and moisture. It ships as dry powder at ambient temperature with no cold pack. The Learn guide on storage of lyophilized research peptides covers temperature and moisture in more detail.

What does ARA-290 16mg cost?

ARA-290 16mg starts at $75.00 per vial. 3-vial packs are 7% off and 5-vial packs are 14% 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. ARA-290 16mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.
