LDLR Protein, Human (HEK293)
LDLR Protein plays a pivotal role in cholesterol homeostasis, binding to LDL and mediating cellular uptake through endocytosis. Clustering into clathrin-coated pits is essential for internalization. In microbial infection, LDLR acts as a receptor for hepatitis C virus in hepatocytes, emphasizing its dual functionality in cholesterol metabolism and the cellular response to viral infections. LDLR Protein, Human (HEK293) is the recombinant human-derived LDLR protein, expressed by HEK293, with tag free.
- Species: Human
- Source: HEK293

Description
LDLR Protein plays a pivotal role in cholesterol homeostasis, binding to LDL and mediating cellular uptake through endocytosis. Clustering into clathrin-coated pits is essential for internalization. In microbial infection, LDLR acts as a receptor for hepatitis C virus in hepatocytes, emphasizing its dual functionality in cholesterol metabolism and the cellular response to viral infections. LDLR Protein, Human (HEK293) is the recombinant human-derived LDLR protein, expressed by HEK293, with tag free.
Background
The LDLR Protein serves as a crucial mediator in cholesterol homeostasis by binding to low-density lipoprotein (LDL), the primary cholesterol-carrying lipoprotein in plasma, and facilitating its cellular uptake through endocytosis. To enable internalization, receptor-ligand complexes must first cluster into clathrin-coated pits. Additionally, in the context of microbial infection, LDLR acts as a receptor for the hepatitis C virus within hepatocytes, although this interaction does not occur through a direct binding with viral proteins. This dual functionality underscores the diverse roles of LDLR in both cholesterol metabolism and the cellular response to viral infections.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
