SEROLOGY

What is Forensic Serology? Forensic serologist  analyze semen, feces, urine, saliva etc. Serology is the identification of blood and blood proteins. Serology is  described as a range of laboratory tests utilizing antigen and serum antibody reactions. There are two different types of blood/body fluids transfer. Direct transfer and indirect transfer. Current serological tests analyses  the …

Sanger Sequencing

Sequencing is a process of determining the precise order of nucleotides in a DNA template after amplification using specific loci. Sanger sequencing was invented by Fredrick Sanger in 1977.It is a widely used sequencing method and now replaced by Next-Generation sequencing methods. In Sanger sequencing, only  fragments of DNA (specific locus) can be amplified and …

Length Heterogeneity Polymerase Chain Reaction

Length Heterogeneity Polymerase Chain Reaction   Length Heterogeneity Polymerase Chain Reaction (LH-PCR) reveals the length heterogeneity of amplicons. The procedure indicates the natural variations of insertion and deletion of nucleotides. LH PCR exposes the allelic profile pattern of DNA in a particular loci. Species-specific differentiation is possible using this method. The procedure is rapid simple …
