Description
The C7 monoclonal antibody specifically binds to the low-density lipoprotein (LDL) receptor, a type I membrane protein that is encoded by the LDLR gene. LDL is the major cholesterol-carrying lipoprotein in plasma. Cell surface LDLR controls the level of cholesterol in plasma by binding to and internalizing LDL and transporting it to lysosomes where LDL is degraded, cholesterol is released into the cell, and LDLR is recycled back to the cell surface. Hence LDLR is found in cell-surface and intracellular membranes (eg, clathrin-coated pits, golgi, endosomes, and lysosomes). Expression of LDLR is a marker for in vitro differentiation of hepatocytes from human embryonic stem cells. LDLR is suspected to mediate infections by viruses that associate with lipoprotein in the blood. Mutations in LDLR are largely responsible for Familial Hypercholesterolemia (FH). The C7 monoclonal antibody has been reported to react with bovine and human LDLR, but not LDLRs of mouse, rat, Chinese hamster, rabbit or dog.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

9. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

10. An isotype control should be used at the same concentration as the antibody of interest.
