VIP

Description

VIP is a lyophilized neuropeptide reagent for laboratory work, held in the cognitive and neuroscience side of our research peptides Canada catalogue. Each vial contains 6mg of powder for reconstitution in a solvent of the investigator’s choosing, and each production batch is analysed by an independent lab before it is released. If you are sourcing VIP for receptor work, signalling assays or method development, this page covers what arrives, how it is verified and how to handle it.

Overview

Vasoactive intestinal peptide is one of the more widely referenced neuropeptides in the literature, which makes it a common reference compound in in-vitro neuro and signalling research. It is supplied here as a dry lyophilized powder in a sealed vial — the standard format for peptide reagents, because removing water slows degradation and lets the material be shipped and stored without the losses a solution would see. Reconstitution is left to the researcher so the buffer, concentration and vehicle match the assay rather than a supplier’s assumption. Order a single 6mg vial for a discrete piece of work, or a box of ten where a study runs across multiple sessions or benches and batch consistency matters.

What it is known for

Buyers choose this listing for the paperwork behind it as much as the peptide itself. Every batch goes to Janoshik, an independent analytical laboratory, for HPLC purity and mass spectrometry identity confirmation, and the certificate of analysis you can request is matched to the batch in your hand — not a representative document from an earlier run. For a reagent like VIP, where an ambiguous result is expensive to chase down, knowing the identity and purity of the exact material used is what keeps a result defensible.

Key features

• Lyophilized powder format — Dry peptide is far more stable in transit and storage than a pre-made solution, so the vial you open behaves like the vial that was tested.
• Third-party HPLC purity analysis — An outside lab measures purity, so the figure on the COA is independent of the seller’s own quality claims.
• Mass spectrometry identity confirmation — Confirms the material is the peptide it is labelled as, ruling out mislabelling or substitution before it reaches your assay.
• Batch-matched certificate of analysis — You can tie analytical data to the specific lot used in an experiment, which is what a reviewer or supervisor will ask for.
• 6mg fill per vial — A defined quantity lets you calculate reconstitution volumes to a target concentration without guesswork or reweighing.
• Box of ten option — Keeps a longer study on material from a consistent supply run and reduces the number of separate shipments.
• Cold-stored and shipped from Canada with tracking — Domestic dispatch avoids customs holds at the border and keeps transit time — the part of the journey you control least — short.
• Discreet, tracked packaging — You can confirm the shipment’s position and plan cold storage for the day it lands.

Benefits

• Independent analytical data on the exact lot, so results rest on verified material
• Freedom to choose your own solvent, buffer and working concentration
• Predictable domestic delivery without international customs delays
• Consistent supply for multi-session studies through the ten-vial box
• Documentation ready to file alongside experimental records

Specifications

Typical applications

• In-vitro neuropeptide and receptor signalling research
• Cell-based assay work in cognitive and neuroscience studies
• Use as a reference or comparator peptide in method development
• Analytical method validation and instrument calibration work

Important information

• Research use only. This is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
• Keep the sealed vial cold on arrival; lyophilized peptide is most stable dry and cold.
• Reconstitute with a solvent appropriate to your protocol and handle the vial under conditions suited to your lab’s practice.
• Once in solution, peptides are less stable than the dry powder — prepare the volume your work needs and store any remainder according to your own validated procedure.
• Request the certificate of analysis for your lot and record the batch number against your experimental data.
• Confirm your institution permits receipt and handling of research peptides before ordering.

Common questions

Does it come reconstituted?

No. It ships as a dry lyophilized powder so you can select the solvent, buffer and final concentration your protocol calls for.

How do I get the certificate of analysis?

A batch-matched COA is available on request, showing the HPLC purity and mass spectrometry identity results for the lot you received.

Who performs the testing?

Janoshik, an independent third-party analytical laboratory, separate from us — that independence is the point of the test.

What is the difference between the single vial and the box of ten?

Quantity only. Each vial holds 6mg. The box of ten suits longer studies or shared benches where you want material from a consistent supply on hand.

Will it clear customs?

It ships domestically within Canada with tracking, so there is no international customs step to delay it.

Can this be used on people or animals?

No. It is sold strictly for in-vitro laboratory research and is not for human or veterinary use in any form.

In summary

A 6mg lyophilized VIP vial with independent HPLC and mass spectrometry data behind every batch, shipped cold and tracked within Canada. Available as a single vial or a box of ten, with the COA matched to your lot.
