MB4. Как подбирать праймеры для ПЦР
Практическая биоинформатика・2 minutes read
Primer selection for efficient PCR involves considering length, composition, melting temperature, and avoiding primer dimers, with a melting temperature difference between forward and reverse primers not exceeding 2 degrees. Detailed analysis of proposed primer pairs is necessary to ensure optimal efficiency and specificity in gene editing tasks.
Insights
- Primers for CR should be 18 to 25 nucleotides long, with a cytosine content of 40-60%, and a melting temperature of 50-68 degrees, ensuring efficient PCR.
- The difference in melting temperature between forward and reverse primers should not exceed 2 degrees to maintain PCR specificity and effectiveness.
