Biological Activity

Description Pituitary adenylate cyclase activating polypeptide (PACAP 1-27) is a potent PACAP receptor antagonist.
Targets
PACAP receptor [1]
In vitro
In vitro PACAP27(100 nM) inhibits all Tat-mediated toxic effects including DNA DSBs, and it prevents the induction of neuronal loss induced by Tat(transactivator of transcription). PACAP27, through CCL5, mitigates the effects of Tat-induced neuronal dysfunction exerting its neuroprotective effect[4]. PACAP-27 (EC50=10nM) stimulates glibenclamide-sensitive and DIDS-insensitive iodide efflux in Calu-3 cells[5].
Cell Research Cell lines The pulmonary carcinoma cell line CALU-6
Concentrations 10 pmol/L to 1 μmol/L
Incubation Time 20 h
Method Cells are incubated with PACAP (1-27) (10 pmol/L to 1 μmol/L) or forskolin (5 μmol/L) for 20 h. Thereafter, cells are harvested, and isolation of total RNA, reverse transcriptase-PCR, and subsequent determination of renin mRNA and β-actin mRNA expression using real-time PCR.
In Vivo
In vivo PACAP-27 is potent VIP-like vasodilators of the femoral arterial bed in dogs. In the cardiovascular system, PACAP27 has vasodepressor actions similar to VIP in anesthetized rats. Intra-arterial infusion of PACAP27 induces dose-related increases in peak femoral arterial flow[3].
Animal Research Animal Models beagle dogs
Dosages 0.25, 0.5, 1, 2.5, 5, 10, and 25 pmol/kg
Administration Intra-arterial infusion

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.
