Deoxyribonucleic Acid

Description

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.

The Uses of Deoxyribonucleic Acid

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.

The Uses of Deoxyribonucleic Acid

Carboxy-terminal FLAG-BAP^? Fusion Protein has been used in the immunoprecipitation of the reporter protein in human embryonic kidney (HEK) cell lysate and as a FLAG-tagged control protein in solid-phase binding assay of spermatogenic immunoglobulin superfamily protein (SgIGSF).

General Description

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

Biochem/physiol Actions

The FLAG sequence comprises of the eight-amino acid sequence AspTyrLysAspAspAspAspLys and is hydrophilic. FLAG fusion proteins are expressed in bacterial, yeast and mammalian cells. FLAG epitope-tagged bacterial alkaline phosphatase is employed in immunoaffinity purification. Alkaline phosphatase based fusion protein have wide clinical applications in immunodetection, enzyme immunoassay and enzyme-linked immunosorbent assay.
