Photostabilization of sunscreen oil through preparation of a free-flowing powder

Octyl-p-methoxycinnamate (OMC) is a sun-blocking agent that absorbs ultraviolet (UV) radiation in UVB range. However, when exposed to sunlight, OMC is converted into a less UV-absorbent form, which reduces its effectiveness.

High-performance liquid chromatographic method to measure protein l-isoaspartyl/d-aspartyl o-methyltransferase activity in cell lysates

Protein l-isoaspartyl/d-aspartyl o-methyltransferase (PIMT) is a widely expressed protein repair enzyme that restores isomerized aspartyl residues to their normal configuration. Current methods for measuring PIMT activity have limited sensitivity or require radioactivity.
