Besides those specific for SARS-CoV-2 and its variants, the ...
WebApr 12, 2024 · The main cause of ADO is the failure of primers to anneal and amplify the target location either by sequence alteration in the target sequence or by suboptimal PCR conditions. Let’s understand each scenario, one after another. Genetic alteration: Sequence variation or mutation in any of the alleles of the target sequence cause allelic dropout. WebWhen studying gene expression with real-time polymerase chain reaction (PCR), scientists usually investigate changes – increases or decreases – in the expression of a particular …
