Figure 1. The PathScan® RP ApoE Sandwich ELISA Kit #95652 detects mouse ApoE protein, but not human or rat ApoE. The absorbance at 450 nm for a panel of cell and tissue extracts (0.1 mg/mL for each sample) using the PathScan® RP ApoE Sandwich ELISA Kit #95652 is shown in the left figure. The corresponding western blot using ApoE antibody (mouse reactive) is shown in the right figure. Extracts were prepared from various cells/tissues, including 293T cells that were either mock transfected (293T/mock), or transfected with constructs expressing full-length human ApoE2 (293T/ApoE2), full-length human ApoE3 (293T/ApoE3), or full-length human ApoE4 (293T/ApoE4).

Product Information

Product Description

The rapid protocol (RP) PathScan® RP ApoE Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of mouse ApoE protein in a reduced assay time of 1.5 hours. Incubation of cell lysates and detection antibody on the coated microwell plate forms a sandwich with ApoE in a single step. The plate is then extensively washed and TMB reagent is added for signal development. The magnitude of absorbance for the developed color is proportional to the quantity of mouse ApoE.

Background

Apolipoproteins are plasma lipoproteins that function as transporters of lipids and cholesterol in the circulatory system. Chylomicrons are a fundamental class of apolipoproteins containing very low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL) (1,2).
Human ApoE has three isoforms: ApoE2, ApoE3, and ApoE4. These three isoforms differ in the combination of cysteine and arginine residues located at positions 130 and 176. The ApoE4 isoform contains arginine at both locations (3). Arginine 130 in ApoE4 allows for interaction between carboxy- and amino-terminal domains through orientation of arginine 61, leading to a preference for binding lower density lipoproteins, where ApoE2 and ApoE3 show preference for binding HDL. Mouse ApoE contains similar sequence to human ApoE4, with arginine present at equivalent positions to 130 and 176. However, the mouse sequence lacks arginine at critical position 61, which allows it to behave similarly to human ApoE3, including preferential binding to HDL (4).
