Acsl1 Knockout RAW264.7 Cell Line

The choice depends on whether you are studying ACSL1 (long-chain fatty acyl-CoA synthetase 1)'s role as the principal long-chain FA-CoA activating enzyme or modeling its functions in macrophage lipid metabolism and inflammation. The Knockout line is the standard tool for asking whether ACSL1 is required for these processes — ACSL1 is the major long-chain (C12-C20) fatty acyl-CoA synthetase activating LCFAs for β-oxidation, complex lipid synthesis, and signaling; ACSL1 has been characterized in macrophage lipid metabolism with reported roles in inflammation, particularly LPS-induced inflammation and lipid loading. Overexpression is useful for studying ACSL1 gain-of-function effects. For macrophage lipid-immunology research, the EDITGENE Acsl1 Knockout in RAW 264.7 is highly relevant — RAW 264.7 is a murine macrophage line, and ACSL1 has been characterized with macrophage-specific functions in atherosclerosis and inflammation. Other ACSL family members (ACSL3, ACSL4, ACSL5, ACSL6) expression analysis aids interpretation. Rescue with wild-type or catalytically-dead ACSL1 enables structure-function studies. The knockout is valuable for studying macrophage lipid metabolism, atherosclerosis biology, and emerging ACSL family functions in ferroptosis (ACSL4 is the major ferroptosis-promoting ACSL).

Primary applications: • Long-chain FA-CoA synthesis: long-chain acyl-CoA pool analysis by LC-MS in Acsl1-null macrophages. • LPS-induced inflammation: in macrophage activation context, LPS-induced inflammatory cytokine production analysis. • Atherosclerosis modeling: in heterologous foam cell-relevant contexts, oxLDL handling and lipid loading studies. • ACSL family dissection: ACSL3, ACSL4, ACSL5, ACSL6 expression analysis to interpret ACSL1-specific functions. EDITGENE recommends this RAW 264.7 macrophage model for researchers investigating macrophage lipid metabolism and atherosclerosis biology.

Yes. ACSL1 rescue experiments require attention to acyl-CoA synthetase architecture: • Construct design: use a codon-modified Acsl1 sequence with a small C-terminal tag (FLAG, HA). ACSL1 has FACS (fatty acyl-CoA synthetase) family architecture with ATP-binding and FA-binding regions — preserve all elements. • Catalytically-dead rescue: ATP-binding region mutations abolish acyl-CoA synthetase activity. • Functional readout: rescue should restore long-chain acyl-CoA synthesis activity. RAW 264.7-specific considerations: • RAW 264.7 is a murine macrophage cell line widely used as a continuous macrophage model for innate immunity and metabolic-immunology research. • Lentiviral transduction is supported with moderate efficiency. • Characterize basal macrophage marker expression and stimulus responsiveness (LPS, IFN-γ) before phenotypic assays.
