Its the cell membrane (or plasma membrane), composed of phospholipid bilayer ,membrane proteins and cholesterol in eukaryotes. the regulation is largely by way of signalling molecules that interact with specefic receptors on the membrane (mostly proteins or glycoproteins). hope that helps Dr. David
Sandwich ELISA uses two antibodies to detect an antigen, while direct ELISA uses only one antibody. Sandwich ELISA is more sensitive and specific, but direct ELISA is simpler and faster.
The key differences between direct and sandwich ELISA techniques are in the way they detect antigens. In direct ELISA, the antigen is directly attached to the plate and detected using a labeled antibody. In sandwich ELISA, the antigen is captured between two antibodies, one attached to the plate and the other labeled for detection.
Indirect and sandwich ELISA techniques are both used to detect specific proteins, but they differ in how they capture and detect the target protein. In indirect ELISA, the target protein is captured by an antibody that is then detected by a secondary antibody. In sandwich ELISA, the target protein is captured between two antibodies, one that binds to the target protein and another that detects it.

Lipid bilayer is composed of two layers of fat cells organized in two sheets. It is typically about five nanometers thick and surrounds all cells providing the cell membrane structure.
Technically speaking, the energy stored in a sandwich comes from the chemical bonds within the molecules of its ingredients, like carbohydrates, proteins, and fats. When you eat the sandwich, your body breaks down these molecules through digestion to release the stored energy, which is then used for various bodily functions. So, next time you chow down on a sandwich, just remember you're basically fueling your body with a delicious bundle of chemical energy.
