PCR and qPCR
Shop by PCR and qPCR Methods
Preparing samples for PCR or qPCR typically requires extraction and purification of nuclear material. Depending on the sample source, this may involve mechanical manipulation via homogenization or require the use of resins or beads to help bind the nucleic acids prior to purification. Prepare your samples with the help of DNA and RNA extraction, isolation, and purification kits, plus reagents, buffers, and more.

Amplification is performed by combining a DNA segment, polymerase, nucleotide solution, and primers in a PCR tube or microplate. A thermal cycler is used to perform the following steps, repeating the process 35 to 40 times.
Denaturation: Hydrogen bonds are broken, DNA separates.
Annealing: Primers and polymerase bind to the DNA.
Extension: Nucleotides pair with the DNA to form a new complementary strand.

In real-time PCR, RNA is converted to cDNA and then amplified using PCR. Common real-time PCR applications detect expressed genes, examine transcript variants, and create cDNA templates for cloning and sequencing procedures. Find polymerases, oligonucleotides, master mixes, and more below to support your real-time PCR assays.
