Outer layers of the eye, SEM

Outer layers of the eye. Coloured scanning electron micrograph (SEM) of the choroid (top) and sclera (bottom) layers of the eye. The sclera is the white outer layer of the eye. It is composed of tough fibrous connective tissue and covers all of the eye except the cornea. It protects the structures within the eyeball and attaches to muscles that move the eye and maintain its shape. The choroid layer, which lies behind the sclera and in front of the retina, is highly vascular and supplies blood to the back of the eye. It is pigmented to absorb excessive light, preventing internal reflections that would form multiple images on the retina. Magnification: x26 when printed 10 centimetres wide

Vaccine production

DNA vaccine production. Technician checking the quality of a sample of recombinant hepatitis B vaccine. Traditional hepatitis vaccine contains the full virus, which could potentially become active and infect patients. A recombinant vaccine is made by inserting a piece of DNA from the virus into another organism, such as a bacterium. The viral protein is expressed by the genetically modified (GM) bacterium and purified for use as a vaccine. Because the vaccine only contains a viral protein, and not the whole virus, there is no risk of the virus becoming active.
