Alkaline Phosphatase

Alkaline Phosphatase

$145.00 - $420.00
CAS:9001-78-9
Alkaline Phosphatase is derived from a recombinant E. coli strain that carries the TAB5 gene. The enzyme catalyzes the dephosphorylation of the 5' and 3' ends of DNA and RNA phosphomonoesters. Also, it hydrolyses ribose, as well as deoxyribonucleoside triphosphates (NTPs and dNTPs). TAB5 Alkaline Phosphatase acts on 5' protruding, 5' recessed, and blunt ends. Phosphatase can be used in many molecular biology applications, such as cloning or probe end labeling to remove the phosphorylated ends of DNA or RNA. In cloning experiments, dephosphorylation prevents the linearized plasmid DNA from self-ligation. It can also degrade unincorporated dNTPs in PCR reactions to prepare a template for DNA sequencing. The enzyme is completely and irreversibly inactivated by heating at 70°C for 5 minutes, thereby making removal of the phosphatase prior to ligation or end labeling unnecessary.

Storage Buffer 

10 mM Tris-HCl (pH 7.4,25°C), 1 mM MgCl2, 0.01 mM ZnCl2, 50% glycerol. 

 

Unit Definition 

One unit is defined as the amount of enzyme that will dephosphorylate 1 µg of pUC19 vector DNA cut with HindIII (5´ protruding ends), HincII (blunts ends), or PstI (5´ recessed ends) in 30 minutes at 37°C. Dephosphorylation is defined as > 95% inhibition of recirculation in a self-ligation reaction and is measured by transformation into E.coli. 

 

Molecular Weight 

The molecular weight of Alkaline Phosphatase is 35 kDa. 

 

Heat Inactivation

70°C for 5 minutes

 

Storage

Store at -25 ~-15°C for up to 24 months. Avoid repeated freeze-thaw cycles.
