Proteins are large, polymorphous macromolecules that provide an array of structural and functional aspects to the body. Most body structures are comprised of proteins as well as all enzymes. Proteins are made up of smaller sub-units called amino acids in which the sequence of amino acids in a ...
If all enzymes are proteins, are all proteins enzymes? About what percent of the buffering power of body fluids is found in the intracellular proteins? How many different types of enzymes are there in a typical human cell and how is their supply regulated?
While at first sight, the extracellular matrices of plant and animals do not have much in common, a closer look reveals remarkable similarities. In particular, the proteins involved in the adhesion of the cell to the extracellular matrix share many functional properties. At the sequence level, ...
In-Cell ELISA is a highly regarded quantitative method for detecting and measuring proteins in cells. This immunocytochemistry assay determines the concentration of a protein in a cell lysate or culture supernatant, according toabcam.com. The principle behind In-Cell ELISA is that soluble proteins...
Proteins are complex structures in the body. Here, the brightly colored and twisty blobs represent different immune system proteins on the outer layer of a T-cell, a type of white blood cell that helps the body to identify foreign invaders.(Image credit: JUAN GAERTNER/SCIENCE PHOTO LIBRARY via...
a small GTPase, provide the energy that drives transport into the nucleus. But so many proteins ...
I've developed processes for over a dozen different molecules and I often think about what makes a "good" or "optimized" process – and where the pitfalls lie. To me, an optimized process produces highly purified material in a minimal number of batches to meet your clinical timelines and ...
Most genes are recipes for making specific proteins, these recipes are passed down from parents to children, from generation to generation. When someone says “You have your father’s hair”, what they mean is “You appear to have inherited a gene or genes from your father that makes a ...
Different Types of Proteins There are a bunch of different types of protein on offer. You want something that’s high quality, but what does that even mean? Essentially you want it to just have protein in it, no sneaky special extras. ...
new cells. However when the DNA of the cell is damaged, for example when there is a genetic change such as DNA mutation or defective protein synthesis, the cell becomes abnormal. It begins to divide uncontrollably and forms a growth (cancerous tumour), in contrast to the normal cell in ...
