Biological Activity

Description PACAP 6-38 acetate is a PACAP (pituitary adenylate cyclase-activating polypeptide) non-stimulating competitive antagonist with an IC50 value of 2 nM. It also acts as a functional CARTp antagonist in vivo.
Targets
CARTp [2] PACAP receptor [1]
2 nM
In vitro
In vitro

PACAP 6-38 blocks the CARTp-induced phosphorylation of ERK in differentiated cells[2].
Cell Research Cell lines SK-N-MC neuroblastoma cells
Concentrations 30 μM
Incubation Time 4 h
Method

Cells are incubated for 4 h with 300 nM PACAP-38 in the absence or presence of the PACAP antagonist PACAP (6-38), medium is collected, and proteins are separated by SDS/PAGE and blotted onto PVDF membranes. For APPsα detection, membranes are probed with the antibody 6E10 followed by an anti-mouse antibody labeled with HRP, detection is performed with the ECL plus system.
In Vivo
In vivo

Intravesical administration of the PAC1 receptor antagonist, PACAP(6-38) (300 nM), significantly (p ≤ 0.01) increases intercontraction interval (2.0-fold) and void volume (2.5-fold) in NGF-OE mice. PACAP(6-38) has no effects on bladder function in WT mice. Intravesical administration of PACAP(6–38) (300 nM) significantly (p ≤ 0.01) reduces pelvic sensitivity in NGF-OE mice but is without effect in WT mice[4].
Animal Research Animal Models Male Sprague-Dawley rats
Dosages 0.3 nmol, 0.6 nmol, 3 nmol (1.5 Μl/340g)
Administration i.c.v

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
