Thermo Scientific PCR reagents meet high quality standards to generate accurate results from even the most challenging molecular biology applications. Random Decamers are truly random oligo deoxyribonucleotides that can be used to create a pool of cDNAs for subsequent applications, thus providing maximum flexibility.
Thermo Scientific Random Hexamers are truly random oligo deoxyribonucleotides. Hexamers are ideal primers for mRNA with or without a poly-A tail. Hexamers bind more often than decamers, giving higher yields and increased sensitivity when amplifying short fragments.
Thermo Scientific PCR reagents meet high quality standards to generate accurate results from even the most challenging molecular biology applications. Magnesium ions (Mg2+) are an important component of PCR reactions where they interact with the DNA template, dNTPs, and Taq DNA Polymerase.
Adhesive film and foils seals for PCR and qPCR plates. Gas permeable seals and crystallography seals. Adhesive PCR Film Seal:Thermo Scientific Adhesive PCR Plate Seals are a reliable method of sealing plates for PCR applications.
