• 개요

  Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are connected by chemical bonds between the bases: adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along DNA’s backbone encodes biological information, such as the instructions for making a protein or RNA molecule.

• 역사

  Deoxyribonucleic Acid (DNA) was first recognized and identified by the Swiss biologist Johannes Friedrich Miescher in 1869 during his research on white blood cells. The double helix structure of a DNA molecule was later discovered through experimental data by James Watson and Francis Crick. Finally, it was proved that DNA is responsible for storing genetic information in living organisms.

• 용도

  DNA (freeze-dried)(pure biological)(pure vegetal)(deoxyribonucleic acid) is a surface film-forming protein with moisturizing action. DnA’s large macromolecules do not enable it to penetrate the skin. In addition, its affinity with the stratum corneum layer keeps it anchored to the skin’s surface, where it serves to protect and retain skin moisture. Although the use of DnA was particularly popular in the 1980s, its incorporation into cosmetic products since then has practically disappeared. It is usually used in a potassium salt form obtained from fish sperm.

• 일반 설명

  Carboxy-terminal FLAG-BAP Fusion Protein is a 466 amino acid C-terminal FLAG fusion protein of E.coli bacterial alkaline phosphatase (BAP).
