Therefore, adequate measures to avoid contamination from any DNA present in the lab environment (bacteria, viruses, or human sources) are required. Because products from previous PCR amplifications are a common source of contamination, many molecular biology labs have implemented procedures that involve dividing the lab into separate areas. [1]
OLIGO Primer Analysis Software is a software for DNA primer design. [1] [2] The first paper describing this software was published in 1989. [3]The program is a real time PCR primer and probe search and analysis tool.
The design of appropriate short or long primer pairs is only one goal of PCR product prediction. Other information provided by in silico PCR tools may include determining primer location, orientation, length of each amplicon, simulation of electrophoretic mobility, identification of open reading frames, and links to other web resources.

In August 2020, an updated version of the guidelines for the digital PCR method was published to account for improvement in machinery, technologies, and techniques since the original 2013 release. Additional guideline steps were added for data analysis, while also providing a more simplified checklist table for researchers to use. [ 15 ]
A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
MLST databases contain the reference allele sequences and sequence types for each organism, and also isolate epidemiological data. The websites contain interrogation and analysis software which allow users to query their allele sequences and sequence types. MLST is widely used as a tool for researchers and public healthcare workers.
InterSequence-Specific PCR (or ISSR-PCR) is method for DNA fingerprinting that uses primers selected from segments repeated throughout a genome to produce a unique fingerprint of amplified product lengths. [16] The use of primers from a commonly repeated segment is called Alu-PCR, and can help amplify sequences adjacent (or between) these repeats.
Chip-based Digital PCR (dPCR) is also a method of dPCR in which the reaction mix (also when used in qPCR) is divided into ~10,000 to ~45,000 partitions on a chip, then amplified using an endpoint PCR thermocycling machine, and is read using a high-powered camera reader with fluorescence filter (HEX, FAM, Cy5, Cy5.5 and Texas Red) for all ...
