What are cholesterol antibodies?
Anti-cholesterol antibodies are immunoglobulins that specifically recognize and bind cholesterol, an amphipathic sterol lipid that is a core structural component of mammalian cell membranes. In immunodetection assays, these antibodies are commonly used to identify cholesterol and related sterol-metabolizing proteins in tissue samples, cell lysates, and cultured cells. Cholesterol also serves as the metabolic precursor for steroid hormones, bile acids, and vitamin D, and its intracellular trafficking and esterification are tightly regulated. Because dysregulated cholesterol handling is strongly associated with atherosclerosis, metabolic syndrome, and several endocrine disorders, accurate detection of cholesterol and its associated pathway proteins remains a focus of cardiovascular and metabolic research.
Catalog highlights and purchasing considerations
About the Biocompare cholesterol catalog
The Biocompare antibody search tool lists anti-cholesterol antibodies from a range of suppliers, spanning polyclonal and monoclonal formats validated across multiple applications. The listing may also include antibodies against cholesterol-related protein targets, such as 11-beta-hydroxysteroid dehydrogenase type 1 (HSD11B1), the low-density lipoprotein (LDL) particle, and cholesterol oxidase. Western blot, ELISA, and immunohistochemistry are the most common validated applications among these products. In addition, the antibodies mentioned here have been cited across a range of metabolic and endocrine research, including studies on high-fat diet-induced bone loss, hepatic lipid accumulation, and sarcopenia-associated reductions in skeletal muscle index.
Considerations when choosing a cholesterol antibody for research
Confirm that the antibody's intended target is accurate, as many genes carry synonym symbols that can create ambiguity across suppliers. Specificity should be verified against the immunogen sequence or region listed on the product datasheet, since antibodies raised against different epitopes of the same protein can behave differently across applications. Other important selection criteria include antibody clonality (polyclonal versus monoclonal), host species, species reactivity, and the choice of conjugate or label suited to the intended detection method. Supplier-provided validation data, such as western blot bands at the expected molecular weight, immunohistochemistry staining patterns consistent with known tissue distribution, or knockout and knockdown controls, offers the most reliable final check before purchase.
