PCTR3 Chemical Properties,Usage,Production

Description

Protein conjugates in tissue regeneration 3 (PCTR3) is a specialized pro-resolving mediator (SPM) synthesized from docosahexaenoic acid (DHA; ).^1,2 DHA is oxidized to 16S,17S-epoxy-protectin, which is converted to PCTR1 by glutathione S-transferase and to PCTR2 and PCTR3 via peptidases.¹ PCTR3 is found in infected mouse spleens and resolving exudate as well as isolated human spleen and septic plasma.³ It is also found in both M1 and M2 macrophages differentiated from isolated human monocytes.⁴
