Description This product is expressed by Escherichia coli, and the source of the expressed gene is T4 bacteriophage. Due to the simultaneous activity of 5'→3' DNA polymerase and 3'→5' DNA exonuclease, T4 DNA polymerase can be used to flatten the 5' protruding end or flatten the 3' protruding end. It can also be used for labeling DNA probe synthesis through displacement reactions, analyzing the starting point of mRNA transcription through primer elongation, synthesizing the second strand during site-specific mutagenesis, and cloning PCR products that do not rely on linkage reactions.The 3'→5' DNA exonuclease activity of this T4 DNA polymerase is about 100-1000 times higher than Klenow Fragment, and it has higher activity for single stranded DNA than double stranded DNA. This enzyme does not contain exonuclease activity of 5'→3' DNA, and can be inactivated by heating at 70°C for 10 minutes. Metal ion chelating agents can inhibit its activity. Unit definition The amount of enzyme required to incorporate 10 nmol of whole nucleotides into acid insoluble precipitate is defined as 1 active unit (U) within 30 minutes, using thermally denatured calf thymus DNA as a template/primer, at 37°C and pH 8.8. Quality control 2U of this enzyme reacted with 1μg of Closed Circular (RFI) pBR322 DNA at 37℃ for 16 hours, and the electrophoresis bands of the DNA remained unchanged. Shipping and Storage -20°C Components SKU TDP01-01 TDP01-02 T4 DNA Polymerase (3U/μl) 50 μl 250 μl 10×T4 DNA Polymerase Reaction Buffer 1 ml 4x1 ml

T4 Polynucleotide Kinase, abbreviated as T4 PNK, is expressed in Escherichia coli. The gene is derived from T4 bacteriophage and can catalyze the phosphorylation of ATP γ- The 5'-hydroxy terminus and 3'-monophosphate nucleosides of the nucleotide chain (double stranded or single stranded DNA or RNA). T4 PNK also possesses 3'-phosphatase activity, which hydrolyze the 3'-phosphate group from the 3'-phosphate terminus of the oligonucleotide, deoxygenated 3'-monophosphate nucleoside, and deoxygenated 3'-diphosphate nucleoside. The T4 PNK can be used for 5' end labeling or phosphorylation of oligonucleotides, DNA, or RNA; the phosphorylation of 5' single nucleotide or removal of the 3' terminal phosphate group. Heating this product at 75°C for 10 minutes or adding EDTA can inactivate it. Ion chelating agents, phosphates, ammonium ions, KCl ≥50 mM, and NaCl can significantly inhibit its activity. Unit Definition At 37°C, within 30 minutes, the amount of enzyme required for the transfer of 1 nmol of γ- Phosphate group on ATP to the end of 5′-OH on DNA is defined as 1 active unit. Quality Control After multiple column purification, the purity of SDS-PAGE was more than 99%; No contamination of endonuclease, exonuclease, phosphatase and RNase activities was detected. Precautions Because the ammonium salt can strongly inhibit the activity of T4 polynucleotide kinase, the DNA obtained from ammonium salt precipitation cannot be used for the labeling reaction of T4 polynucleotide kinase. PEG can promote the rate and efficiency of phosphorylation reaction, and PEG should be added to the exchange reaction system. When using, the enzyme should be stored in an ice box or on an ice bath, and should be stored at -20°C immediately after use.
