Background Information

ACAA1 (acetyl-CoA acyltransferase 1) is an enzyme involved in lipid β-oxidation and provides substrates to the tricarboxylic acid (TCA) cycle, a critical step in cellular metabolism (PMID:33194642). ACAA1 is also a biomarker in type 2 diabetes (T2D), predicting the pre-diabetic metabolic signature in mouse models (PMID:25784953). Moreover, ACAA1 is highly expressed in TNBC, serving as a potential therapeutic target in ACAA1-high tumors and a predictive biomarker of resistance to CDK4/6 inhibitors for RB1-proficient patients (PMID:37129951).

I tested this ACAA1 antibody on THP1 cells (20 ug total cell lysate) and two nice bands were observed at the most concentrated dilution (1:250), although they were located slightly below the predicted molecular weight.
