Primer dimer - Wikipedia
A primer dimer (PD) is a potential by-product in the polymerase chain reaction (PCR), a common biotechnological method. As its name implies, a PD consists of two primer molecules that have attached to each other because of strings of complementary bases in the primers.
Multiple Primer Analyzer | Thermo Fisher Scientific - US
For analyzing and comparing multiple primer sequences simultaneously. Write or paste your primer sequences to the input field (upper window). The analyzer accepts text and table format (can be copied from an Excel file, for example). Note: This analyzer requires at least 2 primer sequences in the input field.
What are Primer Dimers? – A Beginner’s Guide - Genetic Education
2019年4月15日 · What is a Primer dimer? Primer dimers are short, unwanted and unintended PCR products caused by the amplification of primers. Two types of primer dimers are reported commonly in PCR reactions– Self primer (Homodimer) dimer …
Primer Dimers - UC San Diego Health
Primer Dimers. Primer dimers occur when primers are accidentally designed with inverted regions. This allows them to anneal to other primer molecules and, in effect, become linear mini-templates. A measure of the strength or spontaneity of this dimerizing is the reaction's disassociation constant (DG).

2023年11月27日 · What is a primer dimer? A primer dimer is a small, unintended DNA fragment that can form during a polymerase chain reaction (PCR). How do primer dimers form during PCR? Primer dimers form when primers anneal to each other, instead of binding to their intended target in the template DNA. This can happen for several reasons:
Polymerase Chain Reaction: Basic Protocol Plus Troubleshooting …
Primer dimers can form when primers preferentially self anneal or anneal to the other primer in the reaction. If this occurs, a small product of less than 100 bp will appear on the agarose gel.
Understanding Primer Dimer Checks in PCR - labverra.com
Primer dimers occur when primers, the short sequences of nucleotides used to initiate DNA synthesis, bind to each other instead of to the target DNA. This unintended binding can lead to false-positive results, reduced yield of the desired product, and complications in subsequent analytical procedures.
PCR Troubleshooting 103: How to Address Primer-Dimers
2023年7月5日 · A few common causes for primer dimer in PCR are inadequate primer design, high primer concentration, low annealing temperature, Poor quality primers, prolonged PCR cycles, complementation between primers, and complex templates.

2025年1月5日 · Primer dimer は、最初の熱変性ステップが始まる前にプライマー同士がアニールし伸長することで生じる (1)。 したがって、primer dimer が見える場合には primer とテンプレートの結合が十分でない可能性がある。
Primer designing tool - National Center for Biotechnology Information
Enable search for primer pairs specific to the intended PCR template Help. With this option on, the program will search the primers against the selected database and determine whether a primer pair can generate a PCR product on any targets in the database based on their matches to the targets and their orientations.
