Question 1

What is VIP?

Accepted Answer

Vasoactive intestinal peptide, a 28-amino-acid neuropeptide of the secretin family acting at the VPAC1 and VPAC2 receptors.

Question 2

Why is it in circadian research?

Accepted Answer

In the suprachiasmatic nucleus it keeps individual clock neurons oscillating in step. Without it they keep their own rhythms but lose synchrony with each other.

Question 3

What does it do in other tissues?

Accepted Answer

The receptors raise cAMP, and the outcome depends on the tissue — smooth muscle relaxation, epithelial secretion, or a shift toward regulatory immune phenotypes.

Question 4

What limits working with it?

Accepted Answer

The half-life, reported in minutes. Any protocol has to account for it, which is why stability strategies are themselves a research area.

Question 5

Is it approved as a medicine?

Accepted Answer

No. Clinical investigation in pulmonary hypertension and sarcoidosis has not led to approval, and this vial is research material.

Question 6

What documentation comes with it?

Accepted Answer

A batch certificate of analysis with HPLC purity, linked on this page and verifiable on the testing laboratory's site.
