It has 5'→3' polymerase activity and double-strand specific 5'→3' exonuclease activity, but no 3'→5' exonuclease activity. The Taq DNA Polymerase PCR product is a 3' single A sticky end, which can be directly connected to the TA vector.\u003c\/p\u003e\n\u003cp\u003eThe enzyme is supplied at 5 U\/µL together with 10× PCR Buffer (Mg²⁺ free), 25 mM MgCl₂ and ddH₂O for 50 µL PCR reactions. The final Mg²⁺ concentration in the reaction is 2 mM and can be adjusted between 2 and 5 mM. A 50 µL reaction uses 0.5 µL of enzyme and is cycled at 94°C for 5 min, then 35 cycles of 94°C for 30 sec, 50–60°C for 30 sec and 72°C for 30 sec\/kb, with a final 72°C for 10 min.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eConcentration\u003c\/th\u003e\n\u003ctd\u003e5 U\/µL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnit definition\u003c\/th\u003e\n\u003ctd\u003eIncorporates 10 nmol dNTPs into acid-insoluble material in 30 min at 74°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSource\u003c\/th\u003e\n\u003ctd\u003eRecombinant (E. coli)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eActivities\u003c\/th\u003e\n\u003ctd\u003e5'→3' polymerase and double-strand specific 5'→3' exonuclease; no 3'→5' exonuclease\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurity\u003c\/th\u003e\n\u003ctd\u003eGreater than 99% by SDS-PAGE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular weight\u003c\/th\u003e\n\u003ctd\u003eAbout 90 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied buffers\u003c\/th\u003e\n\u003ctd\u003e10× PCR Buffer (Mg²⁺ free) and 25 mM MgCl₂\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemplate input per 50 µL\u003c\/th\u003e\n\u003ctd\u003eHuman genomic DNA 0.05–0.5 µg; E. coli genomic DNA 10–100 ng; λ DNA 0.5–5 ng; plasmid DNA 0.1–10 ng\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct ends\u003c\/th\u003e\n\u003ctd\u003e3' single A overhang for direct TA vector cloning\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eKit Components\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table bhp-comp-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003e500 U (100 µL) (bulk only)\u003c\/th\u003e\n\u003cth\u003e2500 U (500 µL)\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTaq DNA Polymerase (5 U\/µL)\u003c\/td\u003e\n\u003ctd\u003e100 µL\u003c\/td\u003e\n\u003ctd\u003e500 µL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e10× PCR Buffer (Mg²⁺ Free)\u003c\/td\u003e\n\u003ctd\u003e1 mL\u003c\/td\u003e\n\u003ctd\u003e5 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e25 mM MgCl₂\u003c\/td\u003e\n\u003ctd\u003e1 mL\u003c\/td\u003e\n\u003ctd\u003e5 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eddH₂O\u003c\/td\u003e\n\u003ctd\u003e1 mL × 2\u003c\/td\u003e\n\u003ctd\u003e10 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePCR amplification\u003c\/li\u003e\n\u003cli\u003eAmplification from genomic, λ and plasmid DNA templates\u003c\/li\u003e\n\u003cli\u003eTA cloning of PCR products\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eStorage \u0026amp; Handling\u003c\/h2\u003e\n\u003cp\u003eAll components are stored at -20°C with a shelf life of two years.\u003c\/p\u003e\n\u003ch2\u003eUsage Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTemplate purity is critical; low-purity template should not exceed one tenth of the reaction volume (up to 5 µL per 50 µL).\u003c\/li\u003e\n\u003cli\u003eDilute previously amplified products 1,000–10,000× before re-amplification.\u003c\/li\u003e\n\u003cli\u003ePrimer working concentration is 0.2 µM, prepared from a 10 µM stock.\u003c\/li\u003e\n\u003cli\u003eSet the annealing temperature about 5°C below the primer Tm.\u003c\/li\u003e\n\u003cli\u003eThe cycling program uses 30 sec\/kb of extension, while the manual's notes quote 500 bp\/min; confirm the extension time for long amplicons with the manufacturer.\u003c\/li\u003e\n\u003cli\u003eThaw components on ice and mix by inverting before assembling the reaction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSafety \u0026amp; Regulatory\u003c\/h2\u003e\n\u003cdiv class=\"bhp-warning-box\"\u003e\u003cp\u003eFor research use only.
