Practical guides on primer design, sequence analysis, restriction mapping, and more. Written for researchers and students.
Learn how to pick primers with the right melting temperature, GC content, and length for reliable PCR amplification.
Read article →GC content affects melting temperature, secondary structure, and primer binding. Here is what you need to know.
Read article →Open reading frames reveal where genes are encoded. This guide explains how to identify ORFs across all 6 reading frames.
Read article →Restriction enzyme maps show where specific enzymes cut your DNA. Learn how to read and generate them for cloning and analysis.
Read article →Rare codons slow down ribosomes and reduce protein yield. Learn how codon optimization boosts expression in your host organism.
Read article →CpG islands are found near gene promoters and play a key role in methylation and gene silencing. Learn how to detect and interpret them.
Read article →These guides cover the parts of sequence analysis that most often decide whether an experiment works. If you are setting up a PCR, start with designing PCR primers, then read what GC content does to your melting temperature, because the two are the same problem seen from different angles.
For cloning work, restriction enzyme mapping explains how to pick a digest strategy from a map rather than by trial and error. If you are moving from sequence to protein, open reading frames comes first and codon optimization second. For regulatory and epigenetic questions, CpG islands covers how islands are defined and why methylation silences a promoter.
Every guide pairs with the free PrimerGenius analyzer, so you can run each method on your own sequence while you read about it.
