What is the difference between TB-500 and IGF-1 LR3?

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 IGF-1 LR3?

TB-500 has a molecular weight of about 889 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,222 g/mol, a ratio of 10.25. This means 1 mg of TB-500 contains 1,124.9 nmol versus 109.8 nmol for IGF-1 LR3.

How many mg of IGF-1 LR3 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 IGF-1 LR3 (MW 9111) weighs 10.249 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 TB-500 in moles?

0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of TB-500 (MW 889) would weigh 0.009757 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 TB-500 in moles?

1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of TB-500 (MW 889) would weigh 0.09757 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of TB-500 equals how many mg of IGF-1 LR3 in moles?

10 mg of TB-500 (MW 889) is 11.249 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 102.5 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 IGF-1 LR3 in moles?

2 mg of TB-500 (MW 889) is 2.25 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 20.497 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 IGF-1 LR3 in moles?

5 mg of TB-500 (MW 889) is 5.624 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 51.243 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 IGF-1 LR3 in moles?

15 mg of TB-500 (MW 889) is 16.873 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 153.7 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 IGF-1 LR3 in moles?

20 mg of TB-500 (MW 889) is 22.497 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 205 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
