This image was uploaded in the JPEG format even though it consists of non-photographic data. The information it contains could be stored more efficiently or more accurately in the PNG format or SVG format.
If possible, please upload a PNG or SVG version of this image, derived from a non-JPEG source so that it doesn't contain any compression artifacts (or with existing artifacts removed) and with transparency where appropriate. After doing so, please replace all instances of the JPEG version throughout Wikipedia (noted under the "File links" header), tag the JPEG version with {{obsolete|NewImage.ext}}, and remove this tag.

PCR publication graph. This shows the dependence of use of the PCR technique as a function of availability of the Taq polymerase. The roughly linear increase in number of PubMed database entries for "PCR" (after about 1993) under-estimates the true use of the PCR technique. Many research articles use PCR without mentioning the term "PCR" in the title/Abstract/keywords that were searched to gather these data. The total as of March 2004 is close to 200,000.
