What is the difference between LL-37 and IGF-1 LR3?
LL-37 is the 37-residue active fragment of the human cathelicidin hCAP18, studied in antimicrobial-peptide and innate-immunity research (peptide, MW about 4493 g/mol).
Which is heavier, LL-37 or IGF-1 LR3?
LL-37 has a molecular weight of about 4493 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 4,618 g/mol, a ratio of 2.03. This means 1 mg of LL-37 contains 222.6 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of LL-37?
1 mg of LL-37 (MW 4493) is 222.6 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 2.028 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 LL-37 in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of LL-37 (MW 4493) would weigh 0.04931 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 LL-37 in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of LL-37 (MW 4493) would weigh 0.4931 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of LL-37 equals how many mg of IGF-1 LR3 in moles?
10 mg of LL-37 (MW 4493) is 2.226 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 20.278 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of LL-37 equals how many mg of IGF-1 LR3 in moles?
5 mg of LL-37 (MW 4493) is 1.113 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 10.139 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
