What is the difference between Semax and IGF-1 LR3?
Semax is a heptapeptide analogue of the ACTH(4-7) fragment extended with Pro-Gly-Pro, studied in neuropeptide and BDNF-expression research in rodent models (peptide, MW about 813.9 g/mol).
Which is heavier, Semax or IGF-1 LR3?
Semax has a molecular weight of about 813.9 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,297.1 g/mol, a ratio of 11.19. This means 1 mg of Semax contains 1,228.7 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Semax?
1 mg of Semax (MW 813.9) is 1,228.7 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 11.194 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 Semax in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Semax (MW 813.9) would weigh 0.008933 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 Semax in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Semax (MW 813.9) would weigh 0.08933 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Semax equals how many mg of IGF-1 LR3 in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 55.971 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Semax equals how many mg of IGF-1 LR3 in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 111.9 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of Semax equals how many mg of IGF-1 LR3 in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 335.8 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
