Description Phe-Met-Arg-Phe, amide acetate dose dependently (ED50=23 nM) activates a K+ current in the peptidergic caudodorsal neurons. This peptide appears to localize with neuropeptide Y in some regions of the brain.
In vitro In the molluscan central nervous system, Phe-Met-Arg-Phe, amide (FMRFa) acts on K+ channels in sensory, motor-, and neuroendocrine neurones. Phe-Met-Arg-Phe, amide activates a novel K+ current that is characterized by a combined voltage- and receptor-dependent gating mechanism, with both factors being necessary for opening of the channels[1]. Phe-Met-Arg-Phe, amide (1 μM) significantly inhibits glucose stimulated (300 mg/dL) insulin release (p<0.005) and somatostatin release (p<0.01) from the isolated perfused pancreas. Phe-Met-Arg-Phe, amide (FMRF-NH2) (1 and 10 μM) is without effect on glucagon secretion, either in low glucose (50 mg/dL), high glucose (300 mg/dL), or during arginine stimulation (5 mM)[2].
In vivo Phe-Met-Arg-Phe, amide (FMRFamide) stimulates growth hormone secretion in conscious OVX rats. The presence of Phe-Met-Arg-Phe, amide-like immunoreactivity in neuronal elements in the hypothalamus suggested a role for this in the hypothalamic control of the anterior pituitary function. The injection of 200 ng (313.8 picomoles) of FMRFamide (in 2 uL) produces a significantly increased plasma GH 15 min after injection. The GH-increasing effect of 400-800 ng (627-1255 picomoles) of FMRFamide is already developed after 5 min and lasted up to 30 min[3].

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed n the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
