Immunohistochemical analysis of paraffin-embedded human liver tissue using CPT1A Antibody (HY-P81167, 1/500). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry analysis of Hela cells labeling CPT1A with CPT1A Antibody (HY-P81167) at 1/100 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with CPT1A Antibody (HY-P81167) at 1/100 dilution in quick block buffer overnight at 4 ℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
-
Function
CPT1A catalyzes the transfer of the acyl group of long-chain fatty acid-CoA conjugates onto carnitine, an essential step for the mitochondrial uptake of long-chain fatty acids and their subsequent beta-oxidation in the mitochondrion. Also possesses a lysine succinyltransferase activity that can regulate enzymatic activity of substrate proteins such as ENO1 and metabolism independent of its classical carnitine O-palmitoyltransferase activity. Plays an important role in hepatic triglyceride metabolism. Also plays a role in inducible regulatory T-cell (iTreg) differentiation once activated by butyryl-CoA that antagonizes malonyl-CoA-mediated CPT1A repression. Sustains the IFN-I response by recruiting ZDHCC4 to palmitoylate MAVS at the mitochondria leading to MAVS stabilization and activation. Promotes ROS-induced oxidative stress in liver injury via modulation of NFE2L2 and NLRP3-mediated signaling pathways[1][2][3][4][5][6].
