qPCR are poly- or oligonucleotides which have a complementary base sequence to the gene being searched for and can attach themselves to matching DNA sequences. The stability of annealing depends on correspondence of DNA sequences, GC content and the length of the gene probes.
Probes may be labeled with fluorescent dyes, or other chemicals that permit rapid, quantitative detection. Probes function by hybridizing with a desired complementary sequence, the desired sequence may then be detected via the label associated with the probe. We offer you a wide variety of primers and probes. if you have any questions regarding our products, please contact our customer service via live chat, email, or phone.
