Isopropyl-β-D-thiogalactoside (IPTG) is used in combination with X-gal to detect β-galactosidase activity in blue/white selection assays. When the appropriate vectors are used, blue white screening is an important tool for screening and selecting relevant colonies.
Agilent X-gal (5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside, BCIG) is a premium quality chromogenic substrate of β-Galactosidase. It is used with cloning systems that utilize β-galactosidase activity as an indicator of successful cloning.
The Paq5000 DNA polymerase is a robust Taq substitute that is derived from a Pyrococcus species. This enzyme provides equivalent and often better performance to endpoint Taq DNA polymerase amplification and can be substituted easily into many Taq-based procedures. Robust, cost-effective alternative to Taq Equal to better yield with faster cycling conditions Amplify up to 6 kb genomic DNA targets Easily substituted…
Taq Extender PCR additive improves the reliability and yield of conventional Taq-based PCR amplifications. Taq Extender additive increases the efficiency of Taq DNA polymerase extension reactions during each cycle of PCR by reducing mismatch pausing, resulting in a greater percentage of completed extension reactions.
Pure recombinant high-fidelity DNA polymerase from Thermococcus kodakaraensis KOD1KOD HiFi DNA Polymerase* is a recombinant form of Thermococcus kodakaraensis KOD1 DNA polymerase. KOD HiFi is a high fidelity thermostable polymerase that amplifies target DNA up to 6 kbp in length with superior accuracy and yield. The enzyme’s 3′→5′ exonuclease-dependent proofreading activity results in a lower PCR mutation frequency than any ot…
High-performance enzyme blend for long and accurate PCRKOD XL DNA Polymerase* is an optimized blend of KOD HiFi DNA Polymerase and a mutant form of KOD HiFi that is deficient in 3′→5′ exonuclease activity. This enzyme mixture is designed for reliable amplification of long, complex targets with robust yield and high accuracy. It can also be used for incorporation of dITP, dUTP and derivatized dNTPs in PCR amplicons. KOD XL DNA…

AmpliTaq® DNA Polymerase is a 94 kDa ultra-pure, gelatin-free, thermostable, recombinant DNA polymerase obtained by expression of a modified form of the Thermus aquaticus Taq DNA polymerase gene in E. coli. It is the most thoroughly characterized enzyme available for the polymerase chain reaction (PCR) process and its recombinant nature and purification method provide unparalleled purity and reproducibility, vial-to-vial, lo…
RNA polymerase II features a large carboxyl-terminal repeat domain (CTD) that consists of the consensus heptapeptide Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7. Differential phosphorylation in this CTD orchestrates accessibility for various co-factors of the transcription complex. Using the phosphorylation specific antibodies it is now possible to determine specific phosphorylation states. In addition to phosphorylation specific antib…
