How to design PCR primers For PCR primer design, IDT recommends that you aim for PCR primers between 18 and 30 bases; however, the most important considerations for primer design should be the Tm value and on-target binding efficiency. Primers should also be free of strong secondary structur...

There is provided a method for designing primers for multiplex PCR, for assigning priorities to candidate amplification regions on same chromosomal DNA and designing primers for PCR amplifying the candidate amplification regions according to the priorities, the method having a feature in a method for...
Introducing a universal annealing temperature for primers Primer annealing is a critical step in polymerase chain reaction or PCR. In this step, the primers bind to flanking sequences of the target DNA for amplification. The annealing temperature of th...
Always include control reactions, without template DNA and without enzyme, to ensure the results are truly due to amplification of the right sample. Primer Design for PCR Primers are always specified 5′ to 3′, left to right. Verify that your primers are designed and ordered in the correct...
Primer annealing is a critical step in polymerase chain reaction or PCR. In this step, the primers bind to flanking sequences of the target DNA for amplification. The annealing temperature of this step should be determined from the melting temperature...
The PCR efficiency depends on many factors including: (1) the assay performance, which depends on the primers’ and template sequences and structures. Secondary structure and opportunity for undesired intra-molecular interactions reduce PCR efficiency; (2) the sample matrix, which may contain inhibit...
researchers often resort to affordable Sanger sequencing methods. Preparing DNA samples for sequencing is an important process in itself, which involves primer design, extraction of genomic DNA, and PCR amplification. Download our detailed Genotyping Protocol below for more sample preparation and Sanger ...
The reason we bother calculating PCR primer efficiencies is to be able to correctly analyse the results. For the calculation of gene expression, such as thedelta-delta Ct method, it is assumed that the PCR primer efficiencies are comparable for the gene of interest and for the housekeeping gene...
PCR for bacterial identification and AMR profiling is constrained by the need for primers specific to known pathogens and resistance genes, which inherently limits detection to these predefined targets. Additionally, PCR assays may face inhibition challenges in complex clinical samples such as ...
