Product Description

[Sar9,Met(O2)11]-Substance P TFA is a selective tachykinin NK1 receptor agonist (activator).

Biological Activity I Assay Protocols (From Reference)

Targets	NK1 receptor[1]
ln Vitro	[Sar9,Met(O2)11]-Substance P and septide (10-100 pmol per rat, icv) are equally effective in raising heart rate (HR) and mean arterial blood pressure (MAP), although their time courses are different. Face washing and sniffing are increased dose-dependently by both agonists, but only [Sar9,Met(O2)11]-Substance P causes grooming[1].

Solubility Data

Solubility (In Vitro)	H2O: 100 mg/mL (66.33 mM)
Solubility (In Vivo)	Solubility in Formulation 1: 50 mg/mL (33.16 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication. (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	0.6633 mL	3.3164 mL	6.6327 mL
	5 mM	0.1327 mL	0.6633 mL	1.3265 mL
	10 mM	0.0663 mL	0.3316 mL	0.6633 mL

*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.

Molecular Weight*

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

See Example

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
