I just got spam from a company advertising 30% off my first order of custom peptide synthesis.

They point out that they offer peptide modifications: phosphopeptides, biotinylated peptides, dye-labeled pepties, cyclic peptides, and many more. Free consultation on peptide design. Alternatively, I can have 20% off my first order on amino acids, building blocks, synthesis resins and reagents. And, yes, they offer Wang Resins.

I find this all very strange. Much like the first time I saw chip design software (which can cost upwards of $100k/license/year) being advertised on a billboard.
