What is the difference between Selank and IGF-1 LR3?
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 IGF-1 LR3?
Selank has a molecular weight of about 751.9 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,359.1 g/mol, a ratio of 12.12. This means 1 mg of Selank contains 1,330 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Selank?
1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 12.117 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of Selank in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Selank (MW 751.9) would weigh 0.008253 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 1 mg vial of IGF-1 LR3 equals how many mg of Selank in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Selank (MW 751.9) would weigh 0.08253 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 IGF-1 LR3 in moles?
5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 60.587 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 IGF-1 LR3 in moles?
10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 121.2 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
