What is the difference between Selank and Cartalax?
Selank is a synthetic heptapeptide analogue of tuftsin extended with Pro-Gly-Pro, developed at the Institute of Molecular Genetics in Russia and studied in neuropeptide research (peptide, MW about 751.9 g/mol).
Which is heavier, Selank or Cartalax?
Selank has a molecular weight of about 751.9 g/mol and Cartalax about 333.29 g/mol (PubChem), so Selank is heavier by 418.6 g/mol, a ratio of 2.26. This means 1 mg of Selank contains 1,330 nmol versus 3,000.4 nmol for Cartalax.
How many mg of Cartalax are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Cartalax (MW 333.29) weighs 0.4433 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Selank and Cartalax
PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Cartalax as C12H19N3O8 (333.29 g/mol). Selank is a peptide; Cartalax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 10 mg vial of Cartalax equals how many mg of Selank in moles?
10 mg of Cartalax (MW 333.29) is 30.004 µmol. The same amount of Selank (MW 751.9) would weigh 22.56 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of Cartalax equals how many mg of Selank in moles?
20 mg of Cartalax (MW 333.29) is 60.008 µmol. The same amount of Selank (MW 751.9) would weigh 45.12 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Selank equals how many mg of Cartalax in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Cartalax (MW 333.29) would weigh 2.216 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Selank equals how many mg of Cartalax in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Cartalax (MW 333.29) would weigh 4.433 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
