Product Description
PACAP (6-38), human, ovine, rat TFA is a potent PACAP receptor antagonist. PACAP (6-38) acts on PACAP type I receptor, PACAP type II receptor VIP1 and PACAP type II receptor VIP2, with IC50 of 30 nM, 600 nM and 40 nM respectively.
Biological Activity I Assay Protocols (From Reference)
Targets
IC50: 30 nM (PACAP type I receptor), 600 nM (PACAP type II receptor VIP1), 40 nM (PACAP type II receptor VIP2)[1]
ln Vitro
It is also possible to detect a rise in dopamine (DA) content by HPLC analysis and/or cell proliferation detected by the MTT assay by Dexamethasone (DEX). These effects can be prevented by PACAP (6-38) at concentrations high enough to block the PACAP type 1 (PAC1) receptor. This rise in DA content by 1 μM DEX is strongly inhibited by pretreatment with PAC1 receptor antagonist PACAP(6-38) at 0.1 or 1 μM for 2 hours. DEX promotes cell growth, as demonstrated by the MTT experiment. Furthermore, PACAP's pre-incubation inhibits this effect as well (6-38). DA content and cell proliferation are unaffected by PACAP(6-38) at 1μM for a 24-hour period. It has been reported, meanwhile, that PACAP(6-38) at 0.3 μM can inhibit the spontaneous buildup of tyrosine hydroxylase (TH) in differentiated retinal cultured cells over a period of five days[2].
ln Vivo
In NGF-OE mice, intravesical injection of PACAP (6-38), a PAC1 receptor antagonist, significantly increases both the void volume (2.5-fold) and intercontraction interval (2.0-fold). NGF-OE mice's baseline bladder pressure is likewise reduced by intravesical administration of PACAP (6-38). While PACAP (6-38) (300 nM) administered intravenously considerably (p≤0.01) lowers pelvic sensitivity in NGF-OE mice, it has no impact in WT animals[3].

Solubility Data
Solubility (In Vitro)
DMSO :~100 mg/mL (~24.16 mM)
H2O :~50 mg/mL (~12.08 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (0.60 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (0.60 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

Solubility in Formulation 3: 100 mg/mL (24.16 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
