Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
Describe the two general types of protein microarrays. What are
their possible applications?
A protein microarray is also known as the protein chip, is the high throughput method that is used to trace the activities and interaction of the proteins as well as for the determination of their function. A large number of proteins can be traced in parallel. These microarrays are economical, automated, highly sensitive and rapid as well they consume very small quantities of reagents and samples. The high throughput technology is based on technology developed for the DNA microarray.
