Affymetrix, the makers of GeneChip arrays.
The quartz wafer is in the holding position on the DNA synthesizer. The wafer is moved to a vertical reaction vessel for the process of DNA chain elongation.
A technician loads a quartz wafer into the DNA synthesizer, where nucleotides will be added to selected sequences to build probes.
A technician uses a computer guiding system to align the filter mask in perfect register with the quartz wafer. The filter mask will block light to selected regions of the wafer. More nucleotides can be added to the exposed regions.
Here a technician aligns a quartz wafer, from which 50-400 GeneChips are prepared for mounting.
David Goeddel was one of the first scientists Herb Boyer hired for the insulin project. Here, David Goeddel talks about Genentech's general strategy for synthesizing insulin.
Shows the biosynthetic pathways that lead to the synthesis of carotenoids and anthocyanins in plants.
Arthur Kornberg isolated the first enzyme, DNA polymerase I, which can make new DNA strands.
Apparatus used by Stanley Miller in the synthesis of organic molecules.
