84kDa

84kDa refers to a specific molecular weight, typically used to describe proteins or other biomolecules with a mass of approximately 84 kilodaltons (kDa). The dalton (Da) is a unit of atomic mass equal to one atomic mass unit (amu), and one kilodalton equals 1,000 Daltons. Molecular weights of proteins are often expressed in Daltons or kilodaltons for clarity and comparison.

Proteins with an approximate molecular weight of 84kDa are involved in various biological functions depending on their structure and origin. For example, some enzymes, receptors, and structural proteins fall within this size range. The molecular weight can provide insights into the protein's size, structural complexity, and possible function, although it is not solely indicative of activity or specific roles.

The determination of a protein's molecular weight is primarily performed through techniques such as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), mass spectrometry, or size-exclusion chromatography. These methods help identify and characterize proteins in research and diagnostic settings.

In scientific literature, the "84kDa" designation acts as a shorthand to refer to a particular protein or fragment characterized by this molecular weight. For example, an antibody might be specific to an epitope on an 84kDa protein, or a protein of this size may be involved in cellular processes like signal transduction, structural support, or transport.

Understanding the properties of proteins at specific molecular weights is essential in molecular biology, biochemistry, and related biomedical sciences. Identifying and studying such proteins can contribute to insights into cellular mechanisms, disease processes, or potential therapeutic targets.
