High Content Analysis (HCA) based Low-Density Lipoprotein (LDL) Uptake Assay Service
Creative Biolabs' service offers a sophisticated platform for assessing cellular uptake of low-density lipoproteins (LDL), a crucial factor in understanding lipid metabolism and cardiovascular health. Utilizing advanced imaging technologies, this service quantitatively evaluates the internalization of fluorescently labeled LDL particles in various cell types under diverse experimental conditions. The high content analysis (HCA) system provides high-resolution images and automated quantification, enabling customers to analyze multiple parameters such as uptake efficiency, subcellular localization, and cytotoxic effects in a high-throughput manner.
Why Do LDL Uptake
LDL uptake is a crucial physiological process for maintaining cellular function and lipid homeostasis. LDL particles serve as carriers of cholesterol and triglycerides, delivering these essential lipids to cells throughout the body. Cells uptake LDL via specific receptors, primarily the LDL receptor, which facilitates the internalization of LDL particles into the cytoplasm. This process is vital for synthesizing cellular membranes, hormones, and bile acids, all of which rely on cholesterol. Additionally, adequate LDL uptake helps ensure that cells have sufficient energy reserves and structural components. However, excessive LDL uptake and accumulation can lead to pathologies such as atherosclerosis, highlighting the importance of regulatory mechanisms governing LDL metabolism.

Publication
This study establishes an automated high-content imaging platform to profile lipid trafficking in human primary leukocytes. The multiparametric analysis quantifies LDL uptake and introduces a novel "lipid mobilization" score, measuring cellular efficiency in depleting lipid stores. Validated with 65 individuals, the research reveals that impaired lipid mobilization correlates with hypercholesterolemia and age. Crucially, combining these functional cellular readouts with a polygenic risk score significantly improves hypercholesterolemia risk stratification over genetic data alone, providing a powerful approach for personalized cardiovascular risk assessment.

FAQs
How does HCA compare to standard ELISA or flow cytometry for LDL uptake?
Our HCA assay measures multiparametric data on a per-cell basis, including morphology and subcellular localization, and HCA provides essential mechanistic clarity and enables the detection of off-target effects, information that is simply unavailable through low-content bulk assays.
Can your assay handle complex models, such as patient-derived cells or 3D spheroids?
Yes. Our HCA platform is highly versatile and is specifically optimized for complex, physiologically relevant models, including patient-derived cells and 3D cultures. We customize the imaging and analysis protocols to ensure accurate segmentation and quantification, regardless of cellular complexity.
Is it possible to use the HCA assay to study LDLR degradation or recycling kinetics?
Yes. By precisely controlling pulse and chase times with the fluorescent LDL, we can quantify the rate of LDL internalization and monitor the subsequent trafficking of the LDLR back to the cell surface (recycling) or to the lysosome (degradation).
