| KOD DNA Polymerase from Thermococcus kodakaraensis, Recombinant | KOD is a high fidelity thermostable DNA polymerase that amplifies target DNA up to 6 kbp with superior accuracy and yield for PCR applications. The enzyme's 3'?5' exonuclease-dependent proofreading activity results in a lower PCR mutation frequency than any other commercially available DNA polymerase. The elongation rate and processivity are 5 times and 10 to 15 times higher, respectively, than for Pfu DNA polymerase, resulting in highly accurate and robust yield, in a short reaction time. Higher fidelity than pfu dna polymerase--excellent for cloninggreater yield--extension speed is 2x faster than taq dna polymerase and 5x faster than pfu dna polymerasehigher processivity--sequential nucleotide polymerization is 10- to 15-fold greater than pfu and tli dna polymerasesamplifies plasmid and lambda dna templates up to 6 kbpamplifies genomic dna templates up to 2 kbpno truncated amplification products. Group: Enzymes. Purity: > 90% homogeneous by SDS-PAGE. DNA Polymerase. Storage: at -20°C. Source: E. coli. Species: Thermococcus kodakaraensis. KOD DNA polymease; DNA polymease; KOD. Cat No: NATE-1632. | |
| kojibiose phosphorylase | The enzyme from Thermoanaerobacter brockii can act with α-1,2-oligoglucans, such as selaginose, as substrate, but more slowly. The enzyme is inactive when dissaccharides with linkages other than α-1,2 linkages, such as sophorose, trehalose, neotrehalose, nigerose, laminaribiose, maltose, cellobiose, isomaltose, gentiobiose, sucrose and lactose, are used as substrates. Group: Enzymes. Enzyme Commission Number: EC 2.4.1.230. CAS No. 206566-36-1. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2460; kojibiose phosphorylase; EC 2.4.1.230; 206566-36-1. Cat No: EXWM-2460. | |
