(A) Flowchart of the experiments used for testing the feasibility of the new system for enrichment of cells genome-edited at a single target locus. Four days after transfection with pCGsap1/LDLR, pgRNA#3, and pEGFP-N1, cells were treated with IB4SAP for a short period and cultured in normal medium for more than 10 days. The emerging colonies were propagated for molecular biological and cytochemical analyses; (B) cytochemical staining of clones LA-2 and -6 with AF594-IB4. Untransfected MPEFs were stained as positive control. Phase, photographs taken under light microscopy; AF594-IB4, photographs taken under UV illumination to detect AF594-IB4–derived red fluorescence. Bar = 30 μm; (C) electrophoretic pattern of polymerase chain reaction (PCR) products derived from the amplification of LA-1 to -7. Arrows indicate the size of PCR products for each gene (LDLR and GGTA1). M, 100 bp-ladder markers; (D) direct sequencing of PCR products from LA-2 (left panel) and LA-6 (right panel) using primers specific to LDLR or GGTA1 gene. Arrows above ideograms indicate the sites showing indels. In the bottom of each panel, sequencing results of inserts sub-cloned into TA cloning vector are shown. The numbers of clones examined are shown in parentheses. The translation initiation codon ATG is shown by boxes or in red. PAM is indicated by underlines. The deleted portion in the clones is shown by dotted lines; (E) immunocytochemistry of LA-6 and intact MPEFs (used as positive control) using anti-LDLR antibody. The parental MPEFs reactive to the second antibody (fluorescein-labeled anti-mouse IgG) alone are designated as negative control. All cells were counterstained with DAPI upon reaction with the second antibody. Bar = 30 μm.

Background: LDLR

LDL Receptor (low-density lipoprotein receptor or LDLR) is a key determinant of plasma cholesterol levels and as a ubiquitously expressed cell membrane glycoprotein, it binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells via endocytosis. LDLR is found distributed from plasma membrane to intracellular compartments, cell surface (in the presence of PCSK9) and also localizes to Golgi apparatus as well as early/late endosomes and lysosomes. VLDL, IDL, HDL, and chylomicron remnant are also recognized by LDLR at neutral pH. Receptor-ligand complexes undergo endocytosis via clathrin-coated pits and coated vehicle dispenses to endosomes with LRP6 and ARH (also known as LDLR adaptor protein), connecting LDLR family protein and the endocytic machinery; thereby, acidic condition activates dissociation of internalized ligands. Released ligand particles further travel to lysosomes wherein the ligand is degraded by enzyme, while the receptors recycle back to cell surface. After internalization, LDL particles trigger reduction in HMGCR expression to suppress cholesterol biosynthesis; enhancement of ACAT activity to reduce toxic free cholesterol, and suppression of LDLR synthesis to reduce LDL uptake via SREBPs. Genetic mutations impairing LDLR function results in a condition with extremely elevated serum LDL levels and early onset atherosclerosis known as familial hypercholesterolemia (FH).

Protocols

View specific protocols for LDLR Antibody (C7) - BSA Free (NBP1-78159):


Immunocytochemistry Protocol

Culture cells to appropriate density in 35 mm culture dishes or 6-well plates.
1. Remove culture medium and add 10% formalin to the dish. Fix at room temperature for 30 minutes.
2. Remove the formalin and add ice cold methanol. Incubate for 5-10 minutes.
3. Remove methanol and add washing solution (i.e. PBS). Be sure to not let the specimen dry out. Wash three times for 10 minutes.
4. To block nonspecific antibody binding incubate in 10% normal goat serum from 1 hour to overnight at room temperature.
5. Add primary antibody at appropriate dilution and incubate at room temperature from 2 hours to overnight at room temperature.
6. Remove primary antibody and replace with washing solution. Wash three times for 10 minutes.
7. Add secondary antibody at appropriate dilution. Incubate for 1 hour at room temperature.
8. Remove antibody and replace with wash solution, then wash for 10 minutes. Add Hoechst 33258 to wash solution at 1:25,0000 and incubate for 10 minutes. Wash a third time for 10 minutes.
9. Cells can be viewed directly after washing. The plates can also be stored in PBS containing Azide covered in Parafilm (TM). Cells can also be cover-slipped using Fluoromount, with appropriate sealing.
