In molecular biology , gel extraction or gel isolation is a technique used to isolate a desired fragment of intact DNA from an agarose gel following agarose gel electrophoresis . After extraction, fragments of interest can be mixed, precipitated, and enzymatically ligated together in several simple steps. This process, usually performed on plasmids , is the basis for rudimentary genetic engineering . After DNA samples are run on an agarose gel, extraction involves four basic steps identifying the fragments of interest, isolating the corresponding bands, isolating the DNA from those bands, and removing the accompanying salts and stain. To begin, UV light is shone on the gel in order to illuminate all the ethidium bromide stained DNA. Care must be taken to avoid exposing the DNA to mutagenic radiation for longer than absolutely necessary. The desired band is identified and physically removed with a cover slip or razor blade . The removed slice of gel should contain the desired DNA inside. An alternative method, utilizing SYBR Safe DNA gel stain and blue light illumination, avoids the DNA ... of interest exist.

Image Hair gel.jpg thumb Hair styled with hair gel Hair gel is a hairstyling product that is used to stiffen hair into a particular hairstyle . The results it produces are usually similar to, but stronger than, those of hair spray and hair wax , and weaker than those of hair glue. Types Many brands of hair gel in North America and the United Kingdom come in numbered variants. Higher numbered gels maintain a greater hold on hair, while lower numbers do not make the hair as wiktionary stiff stiff and in some products give the hair a wet look. A category typically referred to as ethnic gels are designed and manufactured specifically for sculpting the hair texture common to African Americans . Ampro Ampro Industries is a common example of this category. Some forms of hair gel include temporary Hair colouring hair coloring for the hair, including variants in unnatural colors associated with various subculture s, and are popular within the Gothic fashion goth and raver subcultures. Fact date February 2007 Cationic polymers cation Cationic polymer s are one of the main functional component of hair gel. The positive charges in polymer causes it to stretch, making the gel more viscosity viscous . Hair gels resist natural protein conformations and allow hair to be styled and textured. This is because the stretched out polymer takes up more space than a coiled polymer and thus resists the flow of solvent molecules around it. The positive charges also bind the gel to the negatively charged amino acid s on the surface of the keratin molecules in the hair. More complicated polymer formulas exist, e.g. a copolymer of vinylpyrrolidone , methacrylamide , and N vinylimidazole . ref http www.corporate.basf.com basfcorp img stories wipo haargel Haargel e.pdf ref See also Hair mousse Hair wax Pomade References this empty section displays references defined elsewhere reflist cosmetics Category Hairdressing fashion stub de Haargel es Fijador pelo fa fr Gomina id Minyak rambut it Gel ... more details
