What is the difference between TB-500 and N-Acetyl Epitalon?

TB-500 is a synthetic acetylated fragment corresponding to the actin-binding region (residues 17-23) of thymosin beta-4, studied in cell-migration and actin research (peptide, MW about 889 g/mol).

Which is heavier, TB-500 or N-Acetyl Epitalon?

TB-500 has a molecular weight of about 889 g/mol and N-Acetyl Epitalon about 432.38 g/mol (PubChem), so TB-500 is heavier by 456.6 g/mol, a ratio of 2.06. This means 1 mg of TB-500 contains 1,124.9 nmol versus 2,312.8 nmol for N-Acetyl Epitalon.

How many mg of N-Acetyl Epitalon are equimolar to 1 mg of TB-500?

1 mg of TB-500 (MW 889) is 1,124.9 nmol. The same number of moles of N-Acetyl Epitalon (MW 432.38) weighs 0.4864 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of TB-500 and N-Acetyl Epitalon

PubChem lists TB-500 as C38H68N10O14 (889 g/mol) and N-Acetyl Epitalon as C16H24N4O10 (432.38 g/mol). TB-500 is a peptide; N-Acetyl Epitalon is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 10 mg vial of TB-500 equals how many mg of N-Acetyl Epitalon in moles?

10 mg of TB-500 (MW 889) is 11.249 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 4.864 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 2 mg vial of TB-500 equals how many mg of N-Acetyl Epitalon in moles?

2 mg of TB-500 (MW 889) is 2.25 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 0.9727 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of TB-500 equals how many mg of N-Acetyl Epitalon in moles?

5 mg of TB-500 (MW 889) is 5.624 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 2.432 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 15 mg vial of TB-500 equals how many mg of N-Acetyl Epitalon in moles?

15 mg of TB-500 (MW 889) is 16.873 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 7.296 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 20 mg vial of TB-500 equals how many mg of N-Acetyl Epitalon in moles?

20 mg of TB-500 (MW 889) is 22.497 µmol. The same amount of N-Acetyl Epitalon (MW 432.38) would weigh 9.727 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
