Using animal testing in the development of cosmetics may involve testing either a finished product or the individual ingredients of a finished product on animals, often rabbits, as well as mice, rats, monkeys, dogs, guinea pigs and other animals. Cosmetics can be defined as products applied to the body to enhance the body's appearance or to ...
It promotes the use of alternative methods for animal testing, but does not oblige the test performer to do so; "Article 25.1 - In order to avoid animal testing, testing on vertebrate animals for the purposes of this Regulation shall be undertaken only as a last resort. It is also necessary to take measures limiting duplication of other tests."

Shiseido Company, Limited (Japanese: 株式会社資生堂, Hepburn: Kabushiki gaisha Shiseidō, pronounced [ɕiseꜜːdoː]) is a Japanese multinational cosmetic company founded in Tokyo, Japan in 1872.
Electrophoresis is a process that enables the sorting of molecules based on charge, size, or shape. Using an electric field, molecules such as DNA can be made to move through a gel made of agarose or polyacrylamide. The electric field consists of a negative charge at one end which pushes the molecules through the gel and a positive charge at ...
A mobility shift assay is electrophoretic separation of a protein–DNA or protein–RNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel). [4] The speed at which different molecules (and combinations thereof) move through the gel is determined by their size and charge, and to a lesser extent ...
Nucleic acid molecules are placed on a gel, where an electric field induces the nucleic acids (which are negatively charged due to their sugar-phosphate backbone) to migrate toward the positively charged anode. The molecules separate as they travel through the gel based on the each molecule's size and shape.
A ligand binding assay (LBA) is an assay, or an analytic procedure, which relies on the binding of ligand molecules to receptors, antibodies or other macromolecules. [1] A detection method is used to determine the presence and amount of the ligand-receptor complexes formed, and this is usually determined electrochemically or through a fluorescence detection method.

Site-directed mutagenesis is used to generate mutations that may produce a rationally designed protein that has improved or special properties (i.e.protein engineering). Investigative tools – specific mutations in DNA allow the function and properties of a DNA sequence or a protein to be investigated in a rational approach. Furthermore ...
