4-Amino-3-hydroxyphenylalanine (1-7 days) levels decrease time-dependently upon UVA irradiation of human red hair pheomelanin, reflecting the conversion of photolabile benzothiazine moieties to benzothiazole moieties^[1].
4-Amino-3-hydroxyphenylalanine (70-157 h) levels decrease time-dependently upon blue light irradiation of bovine RPE melanosomes, reflecting photooxidative conversion of benzothiazine moieties to benzothiazole moieties in pheomelanin^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
