Primer Melting Temperature Calculator Calculate Tm In molecular biology, the primer melting temperature (Tm) is key. It's vital for the success of techniques like PCR and DNA sequencing. This temperature shows how well a primer sticks to its matching DNA or RNA. It's crucial for making these important tools work better and more precisely.
The IDT Primer Calculator is a helpful tool for researchers and scientists involved in molecular biology. It calculates the melting temperature (Tm) of a DNA primer, which is essential for designing efficient polymerase chain reaction (PCR) experiments.
The calculator calculates recommended T m (melting temperature) of primers and PCR annealing temperature based on the primer pair sequence, primer concentration, and DNA polymerase used in PCR. The calculator also calculates the primer length, percentage of GC content, molecular weight, and extinction coefficient.
The primer melting temperature (Tm) is the estimate of DNA-DNA hybrid stability. Knowing the Tm is critical for determining an appropriate annealing temperature (Ta). A Ta that is too high will result in insufficient primer-template hybridization, leading to low PCR product yield. A Ta that is too low may lead to non-specific product amplification.
Use the NEB Tm Calculator to estimate an appropriate annealing temperature when using NEB PCR products. Instructions. Select the product group of the polymerase or kit you plan to use. Select the polymerase or kit from the list of products. If needed, modify the recommended primer concentration. Enter primer sequence pairs (max 3 ambiguities/seq).
1. What is the Annealing Temperature Calculator? Definition: This calculator computes the optimal annealing temperature (\( T_a \)) for the annealing step in a Polymerase Chain Reaction (PCR) based on the melting temperatures of the primer (\( T_m^{\text{primer}} \)) and the target DNA (\( T_m^{\text{target}} \)). Purpose: It is used in molecular biology to ensure specific and efficient primer ...
