  • T4 DNA Polymerase (3U/ul, 50ul)

    T4 DNA Polymerase (3U/ul, 50ul)

    SKU: TDP01-01

    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.

  • T4 Polynucleotide Kinase (10U/μl, 1000U)

    T4 Polynucleotide Kinase (10U/μl, 1000U)

    SKU: TPNK01-01

    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.

  • DNA/RNA Miniprep  Kit (50 Preps)

    Tissue DNA/RNA Miniprep Kit (50 Preps)

    SKU: DR01-01

    The EasyPrepTM DNA/RNA Kit provides a simple and rapid method for simultaneously isolating genomic DNA and total RNA from a biological samples, which includes cultured cells, tissues, whole blood, plasma, serum, and body fluids. This co-purification system saves time on sample handling, avoids the sample variation and saves precious samples, which is essential when the amount of available samples are limited Instead of using proteinase K to digest the biological materials, the EasyPrepTM DNA/RNA Kit applies the lysis buffer directly to the cells or tissues. After homogenization, the lysates are transferred to DNA columns. Thus the time-consuming steps of material preparation are eliminated. The DNA-binding-specific matrix in the DNA column allows the high efficient binding of DNA, while RNA, proteins and other cellular components are passed through the DNA columns and are collected. Genomic DNA are then purified from the DNA columns, while total RNA are purified from the collected eluate through RNA binding columns. Purified DNA can be directly used for downstream applications such as PCR, Southern blotting, sequencing and restriction enzyme digestion, while purified total RNA can be used for RT-PCR, Northern blotting or microarray analysis.  Kit's Contents SKU DR01-01 DR01-02 Storage Preps 50 250 - DNA columns 50 250 RT RNA columns 50 250 RT GD Lysis Buffer 60 ml 260 ml RT DNA Wash Buffer 12 ml 50 ml RT DNA Elution Buffer 10 ml 25 ml RT RNA Wash Buffer 12 ml 50 ml RT DEPC H2O 10 ml 25 ml RT Collection tubes 100 500 RT Manual 1 1 -
