Inter-simple sequence repeat (ISSR) analysis is a technique commonly used for identification of individuals, mostly plant species, based on variation found in the regions between microsatellites. ISSR-PCR uses a single fluorescently labeled primer to target and amplify the region between identical microsatellites. The result is a mix of short, amplified DNA strands that vary widely in length.

This method has a wide range of research applications, including the characterization of genetic relatedness among populations, genetic fingerprinting, gene tagging, detection of clonal variation, cultivar identification, phylogenetic analysis, detection of genomic instability, and assessment of hybridization.

DNA extraction is a critical first step in the experimental workflow of DNA Sequencing and Fragment analysis. The overall quality, accuracy and length of the DNA sequence read can be significantly affected by characteristics of the sample itself, and the method chosen for nucleic acid extraction. Ideal methods will vary depending on the source or tissue type, how it was obtained from its source, and how the sample was handled or stored prior to extraction.
