| Background | Arachidonate 12-lipoxygenase, 12R-type (ALOX12B) is a ~80 kDa protein. Catalyzes the regio and stereo-specific incorporation of a single molecule of dioxygen into free and esterified polyunsaturated fatty acids generating lipid hydroperoxides that can be further reduced to the corresponding hydroxy species. In the skin, acts upstream of ALOXE3 on the lineolate moiety of esterified omega-hydroxyacyl-sphingosine (EOS) ceramides to produce an epoxy-ketone derivative, a crucial step in the conjugation of omega-hydroxyceramide to membrane proteins. Therefore plays a crucial role in the synthesis of corneocytes lipid envelope and the establishment of the skin barrier to water loss. May also play a role in the regulation of the expression of airway mucins. 1. Zheng, Y. et al. (2011) The Journal of biological chemistry 286, 24046-56. PMID: 21558561 2. Boeglin, WE. et al.

A549 cells were fixed with 4% paraformaldehyde for 20 minutes, followed by blocking with 5% goat serum for 1 hour. The cells were then incubated with a primary antibody targeting ALOX12B (HF742014) at a concentration of 28 ug/ml overnight at 4°C. Afterward, the cells were incubated with a secondary antibody, Goat Anti-Rabbit IgG (Alexa Fluor-488) for 50 minutes at room temperature. The localization of ALOX12B was visualized (shown in green), and nuclear DNA was stained with DAPI (shown in blue).
