Serology Presumptive vs. Confirmatory Testing Blood: TMB : Tetramethylbenzidine + H2O2 -> blue/green HemaTrace LMG Luminol BlueStar
Serology Gatekeeper of DNA analysis Extraction Quantification Amplification Capillary Electrophoresis Data Analysis
Amplification PCR = Polymerase Chain Reaction 1.Denature 2.Anneal 3.Extend
Data Analysis Single Source:
Data Analysis Mixture:
Hair Cuticle Scales Cortex Medulla
Hair Stages of hair growth: 1.Anagen 2.Catagen 3.Telogen
Fingerprint Analysis Collecting prints: Porous surfaces (anything that can absorb): Ninhydrin : causes purple reaction DFO : glows when illuminated by light Nonporous surfaces (things that don’t absorb): Powder (black and fluorescent) Pictures Cyanoacrylate (superglue fuming)
Example 1.Look at unknown 1.Shape 2.Minutia 2.Compare
Blood Spatter Analysis Methods: -Angle of Impact -Direction of Travel -Stringing

PCR POLYMERASE CHAIN REACTION Dauphin Island Graduate Neurobiology.
The Life Cycle of Hair Hair proceeds through 3 stages as it develops:
Polymerase Chain Reaction (PCR) Used to amplify a sample of DNA Many applications, including: DNA sequencing Phylogeny Diagnosis of genetic disorders Identity.
What are fingerprints? Impressions left on any surface composed of patterns made by the friction ridges – Same definitions could apply to toe, foot, or.
Latent Prints Forensic Science.
Identification and Characterization of Blood and Bloodstains
Discovered that they are unique. No 2 alike. A classification system was developed. Loops Whorls Arches.
Fingerprinting in the Digital Age
Forensic Science. Latent prints are impressions left by friction ridge skin on a surface, such as a tool handle, glass, door, etc. Prints may be collected.
