APOE Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of ApoE in HepG2 cells using an ApoE recombinant rabbit monoclonal antibody (Product # 701241) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B) and actin stained with Alexa Fluor 594 phalloidin (red) (image C). Image D is a composite image showing cytoplasmic localization of ApoE.

APOE Antibody in Western Blot (WB) — Western blot analysis was performed on Fig 1: Human plasma (Lane 1); Fig 2: Whole cell extracts (30 µg lysate) of Hep G2 (Lane 1) and Caco-2 (Lane 2). The blots were probed with Anti-ApoE Rabbit Monoclonal Antibody (Product # 701241, 2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). In Fig 1, a 36 kDa band corresponding to ApoE was observed. In Fig 2, a 34 kDa band was observed across both cell lines, and, an additional 36 kDa band corresponding to an isoform of ApoE was observed in Lane 1. Known quantity of protein samples were electrophoresed using Novex®NuPAGE®12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

APOE Antibody in Western Blot (WB) — Western blot analysis of ApoE in mouse brain (lane 1) and rat liver lysate (lane 2) using an ApoE recombinant rabbit monoclonal antibody (Product # 701241) at a dilution of 2 µg/mL. Samples were detected using chemiluminescence (ECL). Results show a band at ~34kDa.

Product Specific Information

This antibody is predicted to react with non-human primate and mouse based on sequence homology.

Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.

Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.

Target Information

Apo E (Apolipoprotein E) plays an important role in the metabolism of lipids in the plasma, and is also is a constituent of various plasma lipoprotein-lipid particles. The protein is synthesized in liver, brain, spleen, and the kidney, and concentrations are high in interstitial fluids, where it plays a role in distributing cholesterol from cells where cholesterol is in excess to cells which require cholesterol. Apo E also plays an important role in the formation of very low density lipoprotein and chylomicrons. The Apo E gene is located on chromosome 19 at position 19q13.2.
