What is the difference between SNAP-8 and TB-500?

SNAP-8 is an acetylated octapeptide mimicking the N-terminal end of SNAP-25, studied in cosmetic-science research on SNARE complex formation (peptide, MW about 1075.2 g/mol).

Which is heavier, SNAP-8 or TB-500?

SNAP-8 has a molecular weight of about 1075.2 g/mol and TB-500 about 889 g/mol (PubChem), so SNAP-8 is heavier by 186.2 g/mol, a ratio of 1.21. This means 1 mg of SNAP-8 contains 930.1 nmol versus 1,124.9 nmol for TB-500.

How many mg of TB-500 are equimolar to 1 mg of SNAP-8?

1 mg of SNAP-8 (MW 1075.2) is 930.1 nmol. The same number of moles of TB-500 (MW 889) weighs 0.8268 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of SNAP-8 and TB-500

PubChem lists SNAP-8 as C41H70N16O16S (1075.2 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). SNAP-8 is a peptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 5 mg vial of SNAP-8 equals how many mg of TB-500 in moles?

5 mg of SNAP-8 (MW 1075.2) is 4.65 µmol. The same amount of TB-500 (MW 889) would weigh 4.134 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
