Forensics, the study of evidence that identifies a subject, usually refers to identifying a victim or subject of interest at a crime scene.<\/p>\n<p>Forensic scientists use a variety of techniques for identification, however one that is particularly helpful is DNA profiling. This involves utilizing bodily fluids, hair, or skin particles to identify an individual. In addition to DNA profiling, forensics looks at the other evidence to make certain that the identity of a subject is accurate.<\/p>\n<div id=\"attachment_729\" style=\"width: 145px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.coleparmer.com\/blog\/wp-content\/uploads\/2010\/07\/electrophoresis1.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-729\" class=\"size-thumbnail wp-image-729\" title=\"Electrophoresis\" src=\"https:\/\/www.coleparmer.com\/blog\/wp-content\/uploads\/2010\/07\/electrophoresis1.jpg?w=135\" alt=\"Electrophoresis\" width=\"135\" height=\"150\"><\/a><p id=\"caption-attachment-729\" class=\"wp-caption-text\">Gel XL Ultra V-2 Electrophoresis System<\/p><\/div>\n<p>Electrophoresis techniques allow the identification of DNA sequences.

In PCR, a strand of DNA is amplified and replicated through a series of temperature cycles. PCR requires the use of a temperature stable DNA polymerase that replicates the DNA through an enzymatic process that also requires DNA primers, deoxynucleoside triphosphates, and a suitable buffer solution. Cole-Parmer also offers products for polymerase chain reaction (PCR).
